Principal component analysis of seed maturation transcripts. Embryo and endosperm of maturing AC Domain (a) and RL4452 (b) seeds. Aem, AC Domain embryo; Aen, AC Domain endosperm; Rem, RL4452 embryo; Ren, RL4452 endosperm at 20, 30, 40 and 50 days after anthesis. Principal components (PC)1 representing tissue identity (64.65% in AC Domain and 63.61% in RL4452) and PC2 representing developmental stages (19.74% in AC Domain and 18.55% in RL4452) with a cumulative percentage > 80% in each genotype
