摘要: 运用生物信息学分析方法,对番茄NF-Y家族59?个成员的结构域和进化关系进行分析,并比较番茄NF-Y基因在番茄野生型AC及rin突变体果实成熟过程中的表达量变化,结合转录因子RIN对NF-Y基因DNA的结合能力,分析其可能的互作关系。研究结果为阐述番茄NF-Y转录因子与RIN共同调控果实成熟的功能提供理论依据。

Abstract: In this study, amino acid motifs and evolutionary relationship of 59 tomato nuclear transcription factor Y (NF-Y) members were analyzed using bioinformatics approaches. Furthermore, changes in the expression pattern of tomato NF-Y genes in the wild-type AC and ripening inhibitor (rin) mutant were investigated during fruit ripening. On the basis of the NF-Y gene binding capacity of the transcription factor RIN, their co-regulation on tomato fruit ripening was elucidated.

Key words: tomato fruit, NF-Y, RIN, bioinformatics analysis
