摘要：MADS-box genes play an important role in many developmental processes in plants, especially in flower organogenesis. Yellowhorn (Xanthoceras sorbifolium Bunge) is a monoecious plant, its male and female flowers are formed due to the abortion of flower organs at the later stages of flower development. To investigate the functions of MADS-box genes in flower development, we conducted a comprehensive analysis of MADS-box genes across the yellowhorn genome and discovered 79 XsMADS genes. The analysis of the transcriptome revealed that the XsMADS genes displayed distinct expression patterns during the flower development process. XsSTK showed an upward trend during the critical period for pistil formation and specifically expressed a high level in normal pistil. Moreover, XsSTK over-expression transgenic Arabidopsis exhibited an abnormal phenotype, with swollen ovary, shorter and thicker siliques, suggesting that XsSTK might contribute to ovary development. These findings offer a thorough and organized examination of the MADS-box genes in yellowhorn and lay a foundation for further analyzing the mechanism of sex differentiation in yellowhorn and cultivating new varieties with high-yield and quality.
