摘要

The YABBY gene family encodes transcription factors that play essential roles in plant growth and development. In this study, we performed a systematic genome-wide identification and characterization of the YABBY gene family in Glycine max and Glycine soja. A total of 17 and 15 YABBY genes were identified in the genomes of G. max and G. soja, respectively. The expansion of the YABBY gene family was mainly driven by segmental duplications and transposable elements. Based on expression analysis, we inferred the functions of some YABBY genes. Furthermore, the Ka/Ks values for most YABBY gene pairs were approximately 0.2, suggesting that these genes have undergone strong purifying selection. Additionally, we found that most G. max YABBY genes are potential targets of miRNA regulation. These results provide valuable insight into the functional diversification of the YABBY gene family.
