Abstract

The () gene family is a highly conserved transcription factors involved in plant growth, development, and stress responses. However, have not been systematically analyzed in radish (). Therefore, we performed genome-wide identification and expression pattern, gene structure, and function verifications of radish . We identified 52 radish (), which were unevenly distributed across nine chromosomes. Phylogenetic analysis showed that the were divided into two clades (A and B) and subdivided into three types (I, II, and III). Collinearity analysis revealed that the 52 produced 49 repeat events. Tissue expression profiles revealed differential expression of across different tissues, with higher expression observed in flower organs, particularly petals and anthers. qRT-PCR results indicated that responded to abscisic acid, methyl jasmonate, and abiotic stress (low and high temperatures and drought). Additionally, induced a dwarf phenotype in tomato plants, and -overexpression tomato plants presented significantly decreased expression levels of the gibberellin (GA) synthetic genes , , and , but significantly increased expression of the degradation gene . Thus, might affect plant growth by regulating GA content. Collectively, our study comprehensively identified in radish and provided a reference for further research on these genes.
