Fig. 2From: Generation of an integrated Hieracium genomic and transcriptomic resource enables exploration of small RNA pathways during apomixis initiationPrincipal component analysis of sexual pathway genes in Hieracium ovaries. Principal component analysis of 904 sexual pathway genes in apomictic R35 and D36, sexual P36, m115 and m134, apomict mutants derived from R35, at both the MMC (marked as M) and FM (marked as F) stages. Samples are largely separated by genotype, with developmental stage contributing less to variation. Sex sexual phenotype, Apo apomictic phenotype. Percentage variation for each principal component is shown at each axisBack to article page
