番茄NF-Y转录因子生物信息学分析及其与RIN共同调控果实成熟研究

Bioinformatics Analysis of Tomato Nuclear Factor Y(NF-Y) Transcription Factors and Their Relationship with Ripening Inhibitor(RIN) in Co-Regulating Fruit Ripening

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。

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.
