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

摘要

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-Ygene binding capacity of the transcription factor RIN,their co-regulation on tomato fruit ripening was elucidated.%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.
