生长素响应因子(ARFs)介导的植物花器官发育调控网络与作用机制
The Regulatory Network and Mechanism of Plant Floral Organ Development Mediated by Auxin Response Factors
摘要
Abstract
Auxin response factors(ARFs),as core transcription factors in auxin signal transduction,are deeply involved in the entire process of auxin-regulated plant floral organ development.This review summarizes the key roles of ARFs in regulating floral organ differentiation(such as floral primordium initiation and meristem maintenance)and morphogenesis(development of sepals,petals,stamens,carpels,and regulation of organ boundaries)by responding to auxin signals.It also elaborates on the coordinated regulatory mechanism between ARFs and MADS-box genes in the ABCDE model,and reveals the molecular basis of the network formed through post-transcriptional regulation by miRNAs and interactions with hormone signals such as cytokinins,which together maintain the homeostasis of floral development.This provides a theoretical basis for analyzing the molecular mechanism of plant floral development and offers a theoretical foundation for molecular breeding of flowers.关键词
