Fig. 6From: Amino acid transporter (AAT) gene family in foxtail millet (Setaria italica L.): widespread family expansion, functional differentiation, roles in quality formation and response to abiotic stressesThree variations of expression patterns of duplicated AAT gene groups in foxtail millet. (a) and (b) is for the tandemly and segmentally duplicated gene groups, respectively. The X-axis indicates different tissue at different stage, and the Y-axis represents the FPKM value. Different colored boxes represent different expression patterns. Red boxes: new-functionalization; Blue boxes: sub-functionalization; Yellow boxes: non-functionalizationBack to article page
