Leaf senescence, the last stage of leaf development, is a type of postmitotic senescence and
is characterized by the functional transition from nutrient assimilation to nutrient …

Small RNAs are short non-coding RNAs with a length ranging between 20 and 24
nucleotides. Of these, microRNAs (miRNAs) play a distinct role in plant development …

Leaf senescence is an important developmental process involving orderly disassembly of
macromolecules for relocating nutrients from leaves to other organs and is critical for plants' …

Abstract Phytohormones, including jasmonates (JAs), gibberellin, ethylene, abscisic acid,
and auxin, integrate endogenous developmental cues with environmental signals to …

Plants are challenged with numerous abiotic stresses, such as drought, cold, heat, and salt
stress. These environmental stresses are major causes of crop failure and reduced yields …

Leaf senescence is a highly coordinated, complicated process involving the integration of
numerous internal and environmental signals. Salicylic acid (SA) and reactive oxygen …

Plants initiate senescence to shed photosynthetically inefficient leaves. Light deprivation
induces leaf senescence, which involves massive transcriptional reprogramming to …

摘要植物激素是指植物通过自身代谢产生的, 在很低浓度下就能产生明显生理效应的一些有机
信号分子, 在植物生长发育及环境响应过程中具有至关重要的作用. 中国科学家利用植物组织离 …

Chlorophyll breakdown is one of the most obvious signs of leaf senescence and fruit
ripening. The resulting yellowing of leaves can be observed every autumn, and the color …

Melatonin, an antioxidant in both animals and plants, has been reported to have beneficial
effects on the aging process. It was also suggested to play a role in extending longevity and …
