Fig. 7From: Genomic insights into host adaptation between the wheat stripe rust pathogen (Puccinia striiformis f. sp. tritici) and the barley stripe rust pathogen (Puccinia striiformis f. sp. hordei)A simplified evolutionary scenario for the host adaptation of Puccinia striiformis f. sp. tritici (Pst) and P. striiformis f. sp. hordei (Psh). a-h: genomes; a, the most recent common ancestor of Puccinia spp.; b, the most recent common ancestor of P. striiformis; c-d and f-g, intermediate ancestor of Pst (e), and Psh (h), respectively. I-III: evolutionary processes; I, gene family gains and expansions during speciation; II, gene losses; III, gene losses, and/or gains, host adaptation. Black circles, conserved genes; colored circles, rapid evolving genes; solid circles, functional genes; and empty circles, loss-of-function genesBack to article page
