From: Identification of Conserved and Diverse Metabolic Shifts during Rice Grain Development

Principal component (PC) analysis of the metabolomes of developing rice grain.
Red, green, blue, violet and gray colors represent samples at 7, 10, 14, 28 and 42 DAF, respectively. Box, square, open triangle and triangle denote grain metabolomes of 9311, Nongken 58, Nipponbare and Qingfengai, respectively. PC 1 explains 53.3% of variance distinguishing rice grains from different developmental stages.
