MADS盒转录因子参与植物生长发育过程中的许多重要过程。迄今为止，很少有黄瓜MADS盒基因和组织表达谱的报道。最近完成的黄瓜全基因组测序，允许全基因组分析的MADS-box基因家族在黄瓜，以及它与其他物种的比较。在这里，我们进行了全面的分析43黄瓜MADS盒基因，并将它们与拟南芥，白杨，葡萄藤。系统发育分析表明，除AG成员外，大部分黄瓜成员与其他物种的系统发育相似。同时，黄瓜基因组中不存在FLC、AGL 12和Bs三个亚家族。保守基序分析表明，MADS结构域以外的大部分基序只分布在特定的群体中。染色体定位分析表明，串联重复可能有助于MADS-box基因扩增。表达分析表明，43个黄瓜MADS盒成员中有42个在多种植物组织中表达，从而暗示了它们在植物中的各种作用。
MADS-box transcription factors are known to be involved in many important processes during plant growth and development. To date, few cucumber MADS-box genes and little tissue expression profiling have been reported. Recent completion of the cucumber whole-genome sequencing has allowed genome-wide analysis of the MADS-box gene family in cucumber as well as its comparison with other species. Here, we performed comprehensive analyses of the 43 cucumber MADS-box genes and compared them with those in Arabidopsis, poplar, and grapevine. The phylogenetic analysis showed that most cucumber members were comparable with those in other species, with the exception of AG members. At the same time, the three subfamilies FLC, AGL12, and Bs were absent in the cucumber genome. The conserved motif analysis revealed that most motifs outside the MADS domain were distributed only in specific groups. The analysis of chromosomal localization suggested that tandem duplication might contribute to the MADS-box gene expansion. Expression analysis revealed that 42 of 43 cucumber MADS-box members were expressed in multiple plant tissues, thereby implying their various roles in plants.
