Fig. 4From: Genome-wide identification of ATP binding cassette (ABC) transporter and heavy metal associated (HMA) gene families in flax (Linum usitatissimum L.)Expression profiling of the 160 differentially expressed genes in eight different tissues based on log fold-changes, including 143 LuABC genes (a), nine LuHMA genes (b), and eight potential Cd candidate genes (c). The red represents up-regulated genes and blue is for down-regulated ones. The remaining 48 LuABC and one each HMA (LuHMA5) and Cd (LuABCG58) genes were discarded because they were represented by less than 5 RPM (reads per million) after normalization of the data. Expression in anther tissue was used as a reference for expression analysisBack to article page
