Fig. 1From: Genome-wide analysis of the rice PPR gene family and their expression profiles under different stress treatmentsNumbers of PPR genes and their intron numbers in rice and other species. a PPR proteins in a rice:P subgroup (246), PLS subgroup (24), E subgroup (90) and DYW subgroup (131). b Numbers and subclasses of PPR genes in moss, rice, Arabidopsis, tomato and foxtail millet,. c PPR genes distribution on rice 12 chromosomes. Chromosome 1 contained the most PPR genes (14.6%) and chromosome 9 had the fewest PPR genes (4%). d Number of introns in rice, Arabidopsis, tomato and foxtail milletBack to article page
