Fig. 3From: 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 efficiencySchematic representations for the chromosomal distribution and segmental duplication events of rice PTR genes. The duplicated blocks were connected with clolored lines. The PTR genes tightly arranged together represent gene cluster. The different-colored arcs indicate different chromosomes. The chromosome number is indicated at the bottom of each chromosomeBack to article page
