摘　　要：为挖掘玉米YABBY转录因子的功能,本研究通过生物信息学方法,在玉米全基因组水平一共鉴定到12个玉米YABBY转录因子,并对其表达模式进行了分析。结果表明,它们不均等分布在玉米的7条染色体上。所有的ZmYABBY蛋白均含有一个位于N端的C2-C2锌指结构域和C端的YABBY结构域。系统进化分析可将它们分为FIL、CRC、YAB2、YAB1和INO五个亚族。共线性分析发现ZmYABBY基因与禾本科植物存在很好的共线性关系。表达模式分析发现Zm YABBY基因具有特异性表达。这些结果为进一步研究玉米YABBY基因功能提供了理论参考价值。In order to explore the function of YABBY transcription factors in maize,12 YABBY transcription factors were identified by bioinformatics methods at the whole genome level,and their expression patterns were analyzed.The results showed that they were unevenly distributed on 7 maize chromosomes.All ZmYABBY proteins contain a C2-C2 zinc finger domain at the N-terminal and a YABBY domain at the C-terminal.Phylogenetic analysis showed that they could be divided into five subfamilies:FIL,CRC,YAB2,YAB1 and INO.Collinearity analysis showed that Zm YABBY gene had a good collinearity with gramineous plants.Expression pattern analysis showed that Zm YABBY gene was specifically expressed.These results provide a theoretical reference for further study on the function of YABBY gene in maize.
