The MADS-box family gene is a class of transcription factors that have been extensively studied and involved in several plant growth and development processes, especially in floral organ specificity, flowering time and initiation and fruit development. In this study, we identified 69 candidate MADS-box genes and clustered these genes into five subgroups (Mα: 11; Mβ: 2; Mγ: 14; Mδ: 9; MIKC: 32) based on their phylogenetical relationships with . Most genes within the same subgroup showed a similar gene structure and highly conserved motifs. Chromosomal distribution analysis revealed that all the genes were evenly distributed in 10 chromosomes. Additionally, the cis-acting elements of promoter, physicochemical properties and subcellular localization were also analyzed. This study provides a comprehensive analysis of MADS-box genes in and lays the foundation for further functional research.
MADS-box 家族基因是一类转录因子，已被广泛研究并参与了几个植物生长和发育过程，特别是在花器官特异性、开花时间和启动以及果实发育方面。在这项研究中，我们鉴定了 69 个候选 MADS-box 基因，并根据它们与 的系统发育关系将这些基因分为五个亚组（Mα：11；Mβ：2；Mγ：14；Mδ：9；MIKC：32）。同一亚组内的大多数 基因具有相似的基因结构和高度保守的基序。染色体分布分析表明，所有的 基因都均匀分布在 10 条染色体上。此外，还分析了启动子的顺式作用元件、理化性质和亚细胞定位。本研究对 中的 MADS-box 基因进行了全面分析，为进一步的功能研究奠定了基础。
