和而不同:根毛发育过程中生长素与氧化还原信号
Harmony in Diversity:Auxin and Redox Signaling During Root Hair Development
摘要
Abstract
Reactive oxygen species and auxin play important roles in plant growth and development,and their signal transduction and regulatory mechanisms have always been an important field of plant science research.The classic pathway TIR1/AFB-Aux/IAA-ARF mediates nucleic auxin signaling through transcriptional regulation.However,how auxin signal is relayed from cytoplasm to nucleus is still unclear.Recently,Prof Li Chao's team from East China Normal University discovered that redox signals are involved in the auxin-regulated root hairing process.The auxin receptor protein TIR1/AFB2 undergoes Oxi-PTMs before migrating to the nucleus,which determines the initiation of the auxin transcriptional signal for root hair development,and this step is controlled by the upstream FER/LG1-RAC/ROP-RBOHC module.The results of this research have discovered the crosstalk mechanism between auxin and redox signals,and provide a paradigm for regulating biological processes through protein Oxi-PTMs.关键词
