Leaf senescence, the final step of leaf development, is an essential adaptive process that involves intricate regulatory networks mediated by various developmental and environmental clues. Two recent reports, by Zhang Z. et al. and Zhang Y. et al., shed light on how CLE peptides recruit reactive oxygen species (ROS) and ethylene signaling to promote plant leaf longevity.

 摘 要 

叶片衰老是叶片发育的最后阶段，同时也是植物的一个重要适应性过程，涉及到由多种发育和环境信号介导的复杂调控网络。最近，由中国农科院烟草所的郭永峰团队（https://doi.org/10.1016/j.molp.2021.09.006）和北京林业大学李中海团队（https://doi.org/10.1111/nph.18154）报道了CLE多肽如何招募ROS和乙烯信号转导来促进植物叶片的长寿机制。
