Lateral root (LR) formation is a multistep developmental process in which auxin and peptide hormones play essential roles. Recent studies in arabidopsis by Huang et al. and Zhu et al. have revealed that the mitogen-activated protein kinase (MAPK) cascade MKK4/MKK5-MPK3/MPK6 functions in both a noncanonical auxin signaling pathway and the IDA peptide signaling pathway to regulate LR morphogenesis and emergence, respectively.
侧根 (LR) 的形成是一个多步骤的发育过程,其中生长素和肽激素起着至关重要的作用。最近,Huang 等人和 Zhu 等人在拟南芥中的研究揭示了丝裂原活化蛋白激酶 (MAPK) 级联 MKK4/MKK5-MPK3/MPK6 在非经典生长素信号通路和 IDA 肽信号通路中分别发挥作用,以调节 LR 形态发生和出现。
