Fig. 1From: Genome-wide identification of the peptide transporter family in rice and analysis of the PTR expression modulation in two near-isogenic lines with different nitrogen use efficiencyPhylogenetic tree and distribution of PTR genes in Nipponbare. The different-colored arcs indicate different groups. Group V classified into 4 subgroups. Group I, II, III, IVand V contain 20, 15, 26, 4 and 31 genes. Subgroup Va, Vb, Vc, and Vd contain 3, 4, 8 and 16 genesBack to article page
