LBD (lateral organ boundaries domain) gene family, defined by a conserved LOB (lateral organ boundaries) domain segment, is a family of plant-specific transcription factors. Recent studies have shown that LBD family members originated from early terrestrial algae plants, which differentiated during evolution. Thus, LBD family members have various biological functions. Previous studies on the biological function of LBD gene family only focused on plant lateral organs. But recent studies have found that LBD family members are also closely related to plant cell growth and regulation processes such as plant regeneration, plant secondary growth, and environmental stress signal response. With further of research, a molecular metabolic regulation network that relies on the regulation of the LBD gene family is gradually becoming clearer. This paper reviews the structure, classification, evolution, biological functions and molecular metabolic regulation networks involved in the LBD gene family, and summarizes the recent research progress on this gene family in order to better understand the important role of LBD gene family in the growth and development of plants.
