摘要: Auxin is the earliest-discovered hormone in higher plants. It regulates many aspects of plant growth and development through its biosynthesis, polar transport, signaling transduction. In 1970s, brassinosteroids (BRs) were discovered from pollen brassica plants identified as functioning hormones. The function BRs at cellular level mainly promoting cell elongation differentiation. signal transduction pathway well known considered one clearest pathways Both auxin contribute to differentiation GTP-binding proteins are essential elements that mediate receptor downstream members also involved regulation division elongation. Only recently, cross talk communication among these three explored. Cross between depends on G-protein signaling, part. This chapter summarizes detailed mechanisms pathways, knowledge which will help elucidate nature
