Identification of a novel ripening-related transcription factor by neural network inference analysis. A, Transcription factor network generated from an analysis of MG and breaker + 7 stages of ripening in wild-type tomato fruits. Genes are shown as pink circles (for full details of all gene identifiers, see Supplemental Fig. S1 and Supplemental Data Set S1), positive and negative interactions are designated by red and blue arrows, respectively, and the width of the line is proportional to the relative strength of the interaction. The APRR2-Like gene is shown in yellow. B, Expression of the APRR2-Like gene during ripening in the wild type (WT) and fruits of the nonripening mutants rin and Cnr. B, Breaker stage. C, Phylogenetic tree showing the relationship between the tomato APPR2-Like gene (SlAPRR2-Like) and related sequences in Arabidopsis.
