Comprehensive Characterization and Functional Analysis of the Lateral Organ Boundaries Domain Gene Family in Rice: Evolution, Expression, and Stress Response.

ABSTRACT: In this study, the LBD (Lateral Organ Boundaries Domain) gene family, a group of plant-specific transcription factors critical for plant growth and development as well as metabolic regulation, was comprehensively characterized in rice. We identified 36 LBD genes using multi-source genomic data and systematically classified them into Class I (31 genes) and Class II (5 genes). Analysis of their physicochemical properties revealed significant variations in amino acid length, molecular weight, isoelectric points, and hydropathicity. Motif analysis identified conserved LOB domains and other motifs potentially linked to functional diversity. Cis-acting element analysis indicated the involvement of these genes in various biological processes, including light response, hormone signaling, and stres
