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.
