Fig. 8From: 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 stressesComparison on the expressions of orthologous AAT genes in five main tissues between foxtail millet with other 4 species. The outside and the inside rings of (a) to (d) represent foxtail millet and another species, respectively. From the outside to the inside of each ring are the expression levels of AAT genes in leaf, root, stem, grain and spike/inflorescence, respectively. The numbers in the circles represent the correlation coefficients between the expressions of orthologous AAT genes in the two species. * and ** represent correlation significant at the P < 0.05 and P < 0.01 probability level, respectivelyBack to article page
