Abstract

Abstract:

Meristem，flowering genes，hormones，and other factors influence plant type and inflorescence structure. This paper reviews the regulatory network mechanisms affecting the development of inflorescence structure in Arabidopsis thaliana，rice，and tomato. It is found that the genes specifically expressed in the boundary area are the basis for the normal development of inflorescence meristem（IM）and flower meristem（FM）. The development of IM and the determination of FM require the interaction of key regulatory factors such as TFL1，LFY，AP1，SOC1，AGL24，SVP and SEP4. WUS-CLV and WUS-AG feedback systems determine inflorescence structure and flower number by influencing the activity of stem cells. Hormones such as IAA，GA and CTK are the key links in these regulatory networks. In this paper，the formation mechanism of complex inflorescence characters of Solanaceae vegetables was also discussed，and future research is expected to provide a reference for the research on inflorescence morphogenesis and crop breeding.

Key words: inflorescence development, flower bud differentiation, flowering regulation, plant hormone
