Schematic representation of the genomic organization pgip families in rice, wheat, bean, soybean, chickpea, barrel clover and thale cress. Each block-arrow with compound-type lines represents a predicted pgip gene and a block-arrow with dash type lines represents a predicted pseudo-gene or remnant gene. Vertical line within block-arrow indicates introns (Capgip2, Atpgip1, and Atpgip2) or a Copia retrotransposon (Tapgip3). The direction of the arrow indicates ATG to stop codon. The location of pgip genes of legume species are based on Kalunke et al. (2014), those of rice and wheat on Janni et al. (2006) and Di Giovanni et al. (2008), and those of thale crest on Ferrari et al. (2003). Chr, chromosome.
