12月4日,2020年Scientists have discovered that cowpeas -- a type of bean plant -- harbor receptors on the surface of their cells that can detect a compound in caterpillar saliva and initiate anti-herbivore ...
Feb. 16, 2021 —植物具有坚实的免疫反应mechanisms. One such response is 'sensing' attack by herbivorous animals. Researchers discuss 'elicitors' -- the molecules that ...
Mar. 9, 2021 —Arabidopsis thaliana plants produce beta-cyclocitral when attacked by herbivores. This volatile signal inhibits the MEP pathway which is instrumental in plant growth processes, such as the production ...
Dec. 7, 2022 —The ability of tropical forests to grow and store carbon is limited, in part, by herbivory. Insects and other animals prefer to feed on nitrogen-fixing trees, reducing the success of fixers and the ...
Sep. 10, 2020 —Researchers showed that isothiocyanates produced by cruciferous plants to fend off pests serve as oviposition cues. The scientists identified two olfactory receptors whose sole function is to detect ...
June 6, 2022 —A combined defense of different chemical defense substances could result in a negative interaction and mutual detoxification, according to a new study on the wild tobacco species Nicotiana attenuata ...
May 27, 2021 —The oral secretions of herbivorous insects can activate plant defense mechanisms that protect plant cells from being digested. However, scientists have discovered that some larvae 'partner ...
Feb. 3, 2022 —Given the sheer number of potential enemies, plants are resistant to most pests, even if they can cause damage to other plants. Researchers describe a newly discovered mechanism that protects a wild ...
Dec. 12, 2022 —Researchers report that larvae of the cabbage white butterfly use two gut enzymes to effectively disarm the mustard oil bomb, the major chemical defense system of their host plants. Cabbage white ...
Aug. 10, 2021 —The dining time of different insects impacts a plant's defenses and nutritional quality -- a complexity uncovered in new research with implications for pest management ...
