Identification, Molecular Characteristics, and Evolution of YABBY Gene Family in .

The YABBY gene family plays an important role in plant growth and development, such as response to abiotic stress and lateral organ development. TFs are well studied in numerous plant species, but no study has performed a genome-wide investigation of the YABBY gene family in . Therefore, a genome-wide comparative analysis of the YABBY gene family was performed to study their sequence structures, cis-acting elements, phylogenetics, expression, chromosome locations, collinearity analysis, protein interaction, and subcellular localization analysis. A total of nine genes were found, and they were further divided into four subgroups based on the phylogenetic tree. The genes in the same clade of phylogenetic tree had the same structure. The cis-element analysis showed that genes were involved in various biological processes, such as cell cycle regulation, meristem expression, responses to low temperature, and hormone signaling. were unevenly distributed on chromosomes. The transcriptomic data and real-time reverse transcription quantitative PCR (RT-qPCR) expression pattern analyses showed that genes were involved in organ development and differentiation of , and some in the subfamily may have function differentiation. The RT-qPCR analysis showed high expression of flower bud and medium flower. Moreover, all were localized in the nucleus. Therefore, this study provides a theoretical basis for the functional analysis of YABBY genes in .
