Nov. 16, 2021 —New research has uncovered the first fossil evidence of a rare botanical condition known as precocious germination in which seeds sprout before leaving the ...
July 19, 2021 —A new study shows that DNA duplication has been vitally important throughout the evolutionary history of gymnosperms, a diverse group of seed plants that includes pines, cypresses, sequoias, ginkgos ...
Sep. 1, 2020 —New insight on how an enzyme ensures the correct growth of pollen tubes in flowering plants has just been ...
2020年9月14日—Biologists have examined how seed formation is coordinated with fruit growth. They explain the genetic control mechanisms underlying the ...
July 31, 2023 —Researchers have identified a genetic sequence that is essential for plant reproduction. As this region is found in all plant species, it is expected to contribute to future crossbreeding initiatives ...
May 2, 2022 —By quantifying the seed production of more than 700 trees species worldwide and how each species' productivity can vary by location, two new studies can help boost the success of efforts to ...
Apr. 17, 2023 —Insect pollination is a decisive process for the survival and evolution of angiosperm (flowering) plants and, to a lesser extent, gymnosperms (without visible flower or fruit). There is a growing ...
May 2, 2023 —According to researchers, a new analysis of an 80-million-year-old permineralized pollen cone found in the Campanian Holz Shale formation located in Silverado Canyon, California, offers a more ...
Oct. 14, 2020 —The way leaves reflect light, known as plant reflectance spectra, can illuminate the evolutionary history of seed plants, according to researchers. The researchers found that by measuring the light ...
Aug. 21, 2020 —Balanophora have some of the smallest fruits among angiosperms, leading researchers to question how the seeds of these plants are dispersed. Very little is currently known about their seed dispersal ...
