Abstract

The LATERAL ORGAN BOUNDARIES DOMAIN (LBD) protein, named for its LATERAL ORGAN BOUNDARIES (LOB) domain, is a member of a class of specific transcription factors commonly found in plants and is absent from all other groups of organisms. LBD TFs have been systematically identified in about 35 plant species and are involved in regulating various aspects of plant growth and development. However, research on the signaling network and regulatory functions of LBD TFs is insufficient, and only a few members have been studied. Moreover, a comprehensive review of these existing studies is lacking. In this review, the structure, regulatory mechanism and function of LBD TFs in recent years were reviewed in order to better understand the role of LBD TFs in plant growth and development, and to provide a new perspective for the follow-up study of LBD TFs.

Keywords: Function; LBD transcription factors; Regulatory mechanism.
