Significantly altered biochemical pathways and their corresponding gene expression between tolerant and sensitive tomato genotypes under cold stress.

The 92 genes with significant differences in expression between tolerant and sensitive genotypes at 3 d of cold treatment (4°C) were analyzed for significantly (p<0.05) altered biochemical pathways using the Plant MetGenMAP system [33]. (A) Positive (up-regulated) and negative (down-regulated) expression values (log2 ratio cold stress/control) are means of three independent biological replicates.
