Figure 3: Chromosome mapping of stress-related candidate genes.
From: The genome of the stress-tolerant wild tomato species Solanum pennellii
Candidate genes related to salt stress and drought are visualized on their respective IL QTLs for selected ILs 2-5, 7-4-1, 8-3 and 9-1. Colored squares next to each gene represent the magnitude of differential expression (log2) across a range of different tissues and conditions. Red indicates higher expression in S. pennellii, and blue indicates higher expression in S. lycopersicum. Underlined genes are those characterized by large differences in expression between S. lycopersicum cv. M82 and S. pennellii at the promoter and/or coding sequence level. Large differences are characterized as large (>30-bp) indels in the promoter region and/or at least one significant amino acid change in the coding sequence as determined by the P value predicted by SIFT Blink45.
