摘      要：Leaf senescence plays a critical role in a plant’s overall reproductive success due to its involvement in nutrient remobilization and ***,our current understanding of the molecular mechanisms controlling leaf senescence remains *** this study,we show that the receptor-like kinase MALE DISCOVERER 1-INTERACTING RECEPTOR-LIKE KINASE 2(MIK2)functions as a negative regulator of leaf *** found that the SERINE-RICH ENDOGENOUS PEPTIDE 12,previously known to physically interact with MIK2,competes with SCOOP10 to regulate MIK2-dependent leaf *** observed that increased expression of SCOOP10 or the application of exogenous SCOOP10 peptides accelerated leaf senescence in a MIK2-dependent ***,SCOOP12 acted as a suppressor of MIK2-dependent leaf senescence *** assays showed that SCOOP12 enhances while SCOOP10 diminishes MIK2 ***,the SCOOP12-MIK2 module might function antagonistically on SCOOP10-MIK2 signaling at late senescing stages,allowing for fine-tuned modulation of the leaf senescence *** study sheds light on the complex mechanisms underlying leaf senescence and provides valuable insights into the interplay between receptors,peptides,and the regulation of plant senescence.
