It has been known for a decade that the plant MADS genes are important regulators of meristem and floral organ identity. The MADS family in Arabidopsis consists of more than 80 members and, until recently, the function of the majority of these genes was unknown. With the enhanced ability to generate loss-of-function mutants and overexpression lines, the function of the MADS gene family members is beginning to be elucidated. Recent progress demonstrates that MADS genes in Arabidopsis are important regulators not only of meristem and floral organ identity but also of flowering timing and cell-type specification in floral organs.
十年来，人们已经知道植物MADS基因是分生组织和花器官特征的重要调节因子。拟南芥中的MADS家族由80多个成员组成，直到最近，这些基因中大多数的功能还不清楚。随着产生功能缺失突变体和过表达系能力的增强，MADS基因家族成员的功能开始得到阐明。最近的研究进展表明，拟南芥中的MADS基因不仅是分生组织和花器官特征的重要调节因子，也是开花时间和花器官中细胞类型特化的重要调节因子。
