Thu, 07 Sep 2023 10:58:57 EDT //www.koonmotors.com/releases/2023/09/230907105857.htm How does the social behavior of wheat plants influence grain production? //www.koonmotors.com/releases/2023/09/230906112450.htm 研究人员调查的行为方式an individual wheat plant under limiting light conditions influences the performance of the whole community. They assessed morphological and biomass phenotypes of single plants grown in mixtures under sunlight and a simulated canopy shade, and the relevance of these phenotypes for the monoculture community in the field. Wed, 06 Sep 2023 11:24:50 EDT //www.koonmotors.com/releases/2023/09/230906112450.htm Switching from harmful to helpful fungi //www.koonmotors.com/releases/2023/09/230906112431.htm Mold and diseases caused by fungi can greatly impact the shelf life of fruit and vegetables. However, some fungi benefit their hosts by aiding plant survival. Colletotrichum tofieldiae (Ct) is a root mold which typically supports continued plant development even when the plant is starved of phosphorus, an important nutrient for photosynthesis and growth. Researchers studied a unique pathogenic strain of the fungi, called Ct3, which conversely inhibits plant growth. Wed, 06 Sep 2023 11:24:31 EDT //www.koonmotors.com/releases/2023/09/230906112431.htm Agriculture study delivers unexpected results: Cover crops and roots //www.koonmotors.com/releases/2023/09/230906112421.htm Farmers usually plant so-called cover crops after harvesting their main crop in the Fall. This prevents erosion of the soil and nutrient leaching. The roots of these crops also stabilize the structure of the soil. It had been assumed up to now that a mixture of different cover crops would result in particularly intensive rooting. However, a recent study found only limited evidence that this is the case. Instead, mixed cover crops grow thinner roots than when just one single type of cover crop is planted. This result was unexpected. It documents how little is currently understood about the interactions between plant roots. Wed, 06 Sep 2023 11:24:21 EDT //www.koonmotors.com/releases/2023/09/230906112421.htm Making plant-based meat more 'meaty' -- with fermented onions //www.koonmotors.com/releases/2023/09/230905155714.htm Plant-based alternatives such as tempeh and bean burgers provide protein-rich options for those who want to reduce their meat consumption. However, replicating meat's flavors and aromas has proven challenging, with companies often relying on synthetic additives. A recent study unveils a potential solution: onions, chives and leeks that produce natural chemicals akin to the savory scents of meat when fermented with common fungi. Tue, 05 Sep 2023 15:57:14 EDT //www.koonmotors.com/releases/2023/09/230905155714.htm Wood modification boosts biomass conversion //www.koonmotors.com/releases/2023/09/230905125016.htm By adding a naturally-occurring polymer that makes wood more porous, scientists have engineered trees easier to disassemble into simpler building blocks. Tue, 05 Sep 2023 12:50:16 EDT //www.koonmotors.com/releases/2023/09/230905125016.htm Pioneering research sheds surprising new light on evolution of plant kingdom //www.koonmotors.com/releases/2023/09/230905125010.htm A new study has uncovered intriguing insights into the evolution of plant biology, effectively rewriting the history of how they evolved over the past billion years. Tue, 05 Sep 2023 12:50:10 EDT //www.koonmotors.com/releases/2023/09/230905125010.htm 大型食草动物入侵植物保持距离 //www.koonmotors.com/releases/2023/09/230905124952.htm Elephants, buffaloes and other heavy herbivores are effective against invasive plants. This is the conclusion of a new study that used Indian data, including data from the world's largest survey of wildlife based on camera traps. But smaller animals can do the same: you don't need elephants to get the same effect, the researchers point out. Tue, 05 Sep 2023 12:49:52 EDT //www.koonmotors.com/releases/2023/09/230905124952.htm Extreme El Niño weather saw South America's forest carbon sink switch off //www.koonmotors.com/releases/2023/09/230904133132.htm Tropical forests in South America lose their ability to absorb carbon from the atmosphere when conditions become exceptionally hot and dry, according to new research. For a long time, tropical forests have acted as a carbon sink, taking more carbon out of the air than they release into it, a process that has moderated the impact of climate change. But new research found that in 2015 -- 2016, when an El Niño climate event resulted in drought and the hottest temperatures ever recorded, South American forests were unable to function as a carbon sink. Mon, 04 Sep 2023 13:31:32 EDT //www.koonmotors.com/releases/2023/09/230904133132.htm Invasive spotted lanternfly may not damage hardwood trees as previously thought //www.koonmotors.com/releases/2023/09/230901181711.htm In 2012, when the spotted lanternfly (Lycorma delicatula) arrived in the U.S. from its home in China, scientists, land managers, and growers were understandably concerned that the sap-feeding insect would damage native and commercial trees. New long-term research has discovered that hardwood trees, such as maple, willow and birch, may be less vulnerable than initially thought. 星期五,01 Sep 2023 18:17:11 EDT //www.koonmotors.com/releases/2023/09/230901181711.htm Flowering for naught: 120 years with nothing to show //www.koonmotors.com/releases/2023/09/230901124058.htm Flowering for some plants is a yearly occurrence, for others, it is a once-in-a-lifetime event. A widespread species of bamboo in Japan, Phyllostachys nigra var. henonis, takes this one-time flowering event and pushes it to the extreme: they flower once every 120 years before dying to make way for the next generation. Researchers have realized there might be another issue at hand with this monocarpic species, which is the lack of germination of the seeds from a majority of the flowering specimens. Implications of a once dense field of bamboo, something that serves both as a food source and a source of material for crafts, turning to grassland for several years until the regeneration of bamboo begins to start somehow, can impact the ecology of the area in addition to the country's economy. 星期五,01 Sep 2023 12:40:58 EDT //www.koonmotors.com/releases/2023/09/230901124058.htm Algae provide clues about 600 million years of plant evolution //www.koonmotors.com/releases/2023/08/230830160828.htm Researchers generated large scale gene expression data to investigate the molecular networks that operate in one of the closest algal relatives of land plants, a humble single-celled alga called Mesotaenium endlicherianum. Wed, 30 Aug 2023 16:08:28 EDT //www.koonmotors.com/releases/2023/08/230830160828.htm Can this forest survive?

Wed, 30 Aug 2023 13:19:25 EDT //www.koonmotors.com/releases/2023/08/230830131925.htm Curious and cryptic: New leaf insects discovered //www.koonmotors.com/releases/2023/08/230828162413.htm An international research team has described seven previously unknown species of leaf insects, also known as walking leaves. The insects belong to the stick and leaf insect order, which are known for their unusual appearance: they look confusingly similar to parts of plants such as twigs, bark or -- in the case of leaf insects -- leaves. This sophisticated camouflage provides excellent protection from predators as well as presenting a challenge to researchers. Genetic analysis enabled the researchers to discover 'cryptic species', which cannot be distinguished by their external appearance alone. The findings are not only important for the systematic study of leaf insects, but also for the protection of their diversity. Mon, 28 Aug 2023 16:24:13 EDT //www.koonmotors.com/releases/2023/08/230828162413.htm Starch discovery reaps benefits for brewing, baking and milling industries //www.koonmotors.com/releases/2023/08/230825122022.htm Research has brought clarity to the longstanding question of how starch granules form in the seeds of Triticeae crops -- wheat, barley, and rye -- unlocking diverse potential benefits for numerous industries and for human health. 星期五,25 Aug 2023 12:20:22 EDT //www.koonmotors.com/releases/2023/08/230825122022.htm Soils forming on the branches of trees are an overlooked forest habitat //www.koonmotors.com/releases/2023/08/230825122014.htm A study on 'canopy soils' on old trees in Costa Rica shows they are important habitats and carbon stores that cannot easily be replaced. 星期五,25 Aug 2023 12:20:14 EDT //www.koonmotors.com/releases/2023/08/230825122014.htm Sweet corn yield at the mercy of the environment, except for one key factor //www.koonmotors.com/releases/2023/08/230824150202.htm A new analysis has identified the top factors accounting for yield variability in processing sweet corn (used for canned and frozen products), including one within the control of processors. Thu, 24 Aug 2023 15:02:02 EDT //www.koonmotors.com/releases/2023/08/230824150202.htm Fungi-eating plants and flies team up for reproduction //www.koonmotors.com/releases/2023/08/230824111449.htm Fungi-eating orchids were found for the first time to offer their flowers to fungi-eating fruit flies in exchange for pollination, which is the first evidence for nursery pollination in orchids. This unique new plant-animal relationship hints at an evolutionary transition towards mutualistic symbiosis. Thu, 24 Aug 2023 11:14:49 EDT //www.koonmotors.com/releases/2023/08/230824111449.htm Blink and you'll miss these plants shooting their seeds //www.koonmotors.com/releases/2023/08/230823192949.htm When witch hazel plants are ready to disperse their seeds, the woody seed capsules split open, pressure builds up, and eventually the seeds shoot out like a bullet fired from a rifle, hitting 30 feet per second in less than five milliseconds. In a new study, researchers looked into how witch hazels manage to fling heavier seeds just as fast as lighter ones. The secret lies in their spring-loaded fruits. Wed, 23 Aug 2023 19:29:49 EDT //www.koonmotors.com/releases/2023/08/230823192949.htm Tree mortality in the Black Forest on the rise -- climate change a key driver //www.koonmotors.com/releases/2023/08/230823122613.htm Climate impacts such as dry, hot summers reduce the growth and increase the mortality of trees in the Black Forest because they negatively influence the climatic water balance, i.e., the difference between precipitation and potential evapotranspiration. That is the central finding of a long-term study of the influence of climate and climate change on trees in the Black Forest. Wed, 23 Aug 2023 12:26:13 EDT //www.koonmotors.com/releases/2023/08/230823122613.htm Biodiversity protects against invasions of non-native tree species //www.koonmotors.com/releases/2023/08/230823122546.htm Researchers combined human and ecological factors to analyze the global scale of non-native tree species invasions. Human activity in hotspots of global trade, such as maritime ports, is linked to an increased likelihood of non-native tree species invasions. However, a high diversity of native tree species can help to curb the intensity of such invasions. Wed, 23 Aug 2023 12:25:46 EDT //www.koonmotors.com/releases/2023/08/230823122546.htm Fungus gnats as pollinators not pests //www.koonmotors.com/releases/2023/08/230823122515.htm 许多植物和农作物依靠昆虫授粉them so they can reproduce. A new study has shown that several flowering plants from the group Euonymus are pollinated by fungus gnats, a dipteran insect. Specifically, they pollinate Euonymus plants which have red-petaled flowers with short stamens and yogurt-like scent. Although fungus gnats are known to pollinate hundreds of plant species, this study shows that the particular traits of red Euonymus flowers were likely to have been acquired via pollination syndrome, evolving over a process of natural selection to be pollinated specifically by fungus gnats. This research highlights the important role of Diptera, which are commonly regarded as pests, in plant diversity and evolution. Wed, 23 Aug 2023 12:25:15 EDT //www.koonmotors.com/releases/2023/08/230823122515.htm Heat sensor protects the Venus flytrap from fire //www.koonmotors.com/releases/2023/08/230822111724.htm The sensory hairs of the Venus flytrap contain a heat sensor that warns the plant of bush fires.

But the grasses themselves are under threat due to back burning, clearing and disease. Tue, 22 Aug 2023 11:17:09 EDT //www.koonmotors.com/releases/2023/08/230822111709.htm It all depends on the genetic diversity //www.koonmotors.com/releases/2023/08/230821153158.htm New research shows that a single mutation that has immediate effects on plant fitness is maintained over the long term in natural plant populations, despite theories predict the contrary. The researchers located and identified the gene that regulates the amount of an active defense hormone. Mutants in this gene are susceptible to herbivore attack. However, they compensate for impaired defenses through robust genetic networks. When fewer herbivores attack, they even grow faster and produce more offspring. Mon, 21 Aug 2023 15:31:58 EDT //www.koonmotors.com/releases/2023/08/230821153158.htm Climate win-win: Study quantifies benefits of enhanced weathering //www.koonmotors.com/releases/2023/08/230821114412.htm Applying ground-up silicate rock to Midwestern farm fields can capture significant amounts of carbon dioxide and prevent it from accumulating in the atmosphere, according to a new study that successfully quantified those climate benefits for the first time. Mon, 21 Aug 2023 11:44:12 EDT //www.koonmotors.com/releases/2023/08/230821114412.htm Microgreens and mature veggies differ in nutrients, but both might limit weight gain //www.koonmotors.com/releases/2023/08/230816114209.htm Young vegetables known as microgreens are reputed to be particularly good for health. But are microgreens the superfood they're claimed to be, and how do they compare to mature veggies? Scientists have found that their nutritional profiles differ, as do their effects on gut bacteria. Yet, tests in mice suggest that both microgreen and mature vegetables can limit weight gain. Wed, 16 Aug 2023 11:42:09 EDT //www.koonmotors.com/releases/2023/08/230816114209.htm Making plant-based meat alternatives more palatable //www.koonmotors.com/releases/2023/08/230814122358.htm One of the biggest obstacles to the uptake of plant-based alternatives to meat is their very dry and astringent feel when they are eaten. Scientists are now revolutionizing the sensation of plant proteins, transforming them from a substance that can be experienced as gloopy and dry to one that is juicy and plump. And the only substance they are adding to the plant proteins is water. Mon, 14 Aug 2023 12:23:58 EDT //www.koonmotors.com/releases/2023/08/230814122358.htm Researchers find global plant water use efficiency stalled due to climate change //www.koonmotors.com/releases/2023/08/230814122323.htm New findings have found that water use efficiency has stalled since 2001 which implies not as much CO2 was being taken in by plants and more water was consumed and that could have implications on carbon cycling, agricultural production and water resources. Mon, 14 Aug 2023 12:23:23 EDT //www.koonmotors.com/releases/2023/08/230814122323.htm 3D-printed vegan seafood could someday be what's for dinner //www.koonmotors.com/releases/2023/08/230814122218.htm More mock seafood options are needed because of unsustainable fishing and aquaculture practices, which can harm the environment. Now, researchers have a new approach for creating desirable vegan seafood mimics that taste good, while maintaining the healthful profile of real fish. They 3D-printed an ink made from microalgae protein and mung bean protein, and their proof-of-concept calamari rings were air-fried into a snack.

In some fields, this effect increases yields of wheat planted subsequent to maize in the same soil by more than 4%. While the findings from several field experiments show that these effects are highly variable, in the long term they may yet help to make the cultivation of grains more sustainable, without the need for additional fertilizers or pesticides. 星期五,11 Aug 2023 11:54:45 EDT //www.koonmotors.com/releases/2023/08/230811115445.htm The positional transmitter of statoliths unveiled: It keeps plants from getting lazy //www.koonmotors.com/releases/2023/08/230810141032.htm Plants orient their organs in response to the gravity vector, with roots growing towards gravity and shoots growing in the opposite direction. The movement of statoliths responding to the inclination relative to the gravity vector is employed for gravity sensing in both plants and animals. However, in plants, the statolith takes the form of a high-density organelle, known as an amyloplast, which settles toward gravity within the gravity sensing cell. Despite the significance of this gravity sensing mechanism, the exact process behind it has eluded scientists for over a century. Thu, 10 Aug 2023 14:10:32 EDT //www.koonmotors.com/releases/2023/08/230810141032.htm Researchers identify peptides for pollen tube growth in rice //www.koonmotors.com/releases/2023/08/230810110333.htm Rapid alkalinization factors (RALFs) are required for pollen tube germination and elongation, an essential process in plant fertilization. But their role in monocot plants remains unexplored. Scientists have now identified OsRALF17 and OsRALF19 in rice and determined their functions in pollen tube germination and growth. This study provides novel insights into the role of RALFs in rice fertilization, paving the way for enhanced grain yield. Thu, 10 Aug 2023 11:03:33 EDT //www.koonmotors.com/releases/2023/08/230810110333.htm The oldest and fastest evolving moss in the world might not survive climate change //www.koonmotors.com/releases/2023/08/230809130617.htm A 390-million-year-old moss called Takakia lives in some of Earth's most remote places, including the icy cliffs of the Tibetan Plateau. In a decade-long project, a team of scientists climbed some of the tallest peaks in the world to find Takakia, sequence its DNA for the first time, and study how climate change is impacting the moss. Their results show that Takakia is one of the fastest evolving species ever studied -- but it likely isn't evolving fast enough to survive climate change.

Thu, 20 Jul 2023 12:49:05 EDT //www.koonmotors.com/releases/2023/07/230720124905.htm Form and function of island and mainland plants //www.koonmotors.com/releases/2023/07/230714163216.htm Oceanic islands provide useful models for ecology, biogeography and evolutionary research. Many ground-breaking findings -- including Darwin's theory of evolution -- have emerged from the study of species on islands and their interplay with their living and non-living environment. Now, an international research team has investigated the flora of the Canary Island of Tenerife. The results were surprising: the island's plant-life exhibits a remarkable diversity of forms. But the plants differ little from mainland plants in functional terms. However, unlike the flora of the mainland, the flora of Tenerife is dominated by slow-growing, woody shrubs with a 'low-risk' life strategy. 星期五,14 Jul 2023 16:32:16 EDT //www.koonmotors.com/releases/2023/07/230714163216.htm Colonization influences worldwide distribution of plant specimens //www.koonmotors.com/releases/2023/07/230714131131.htm Plant diversity in nature is generally highest in tropical regions around the equator, with decreasing diversity closer to the poles. Researchers now show that the plant specimens housed in herbaria in Europe and North America are more comprehensive and diverse than the collections housed in the countries with more natural plant diversity. 星期五,14 Jul 2023 13:11:31 EDT //www.koonmotors.com/releases/2023/07/230714131131.htm Multiple uses of tropical mosaic landscapes //www.koonmotors.com/releases/2023/07/230714131126.htm Many landscapes in the tropics consist of a mosaic of different types of land use. How people make use of these different ecosystems, with their particular plant communities, was unclear until now. Researchers, many of them from Madagascar, have now investigated this. When considering biodiversity, forests often get the most attention. But this research shows that rural households use a wide range of plant species and services provided by many nearby ecosystem types. 星期五,14 Jul 2023 13:11:26 EDT //www.koonmotors.com/releases/2023/07/230714131126.htm Building a better forest tree with CRISPR gene editing //www.koonmotors.com/releases/2023/07/230713141912.htm Researchers use CRISPR techniques to modify lignin levels in poplar trees. 星期四,13Jul 2023 14:19:12 EDT //www.koonmotors.com/releases/2023/07/230713141912.htm Newly identified protein regulates the creation of cellulose in plant cells //www.koonmotors.com/releases/2023/07/230711130631.htm A team has identified a protein that modifies the cellular machinery responsible for producing cellulose, which could inform the design of more stable, cellulose-enriched materials for biofuels and other functions.
