Extended Data Fig. 4: The strength and pattern of selection on Indica rice-leaf transcript levels under drought conditions differ across fitness components.
From: The strength and pattern of natural selection on gene expression in rice
a, The strength of selection |S| on gene expression differed between selection for flowering success (lime), and fecundity (green) in the dry field. Mann–Whitney U-test, two-sided P < 0.001, n = 15,343. b, Positive directional selection (n = 11,304) was stronger than negative selection (n = 4,039) for fecundity under drought (green) (Mann–Whitney U-test, two-sided P < 0.001), and selection for flowering success showed higher absolute values (Kolmogorov–Smirnov test, two-sided P < 0.001, n = 15,343). c, Patterns of quadratic selection differed significantly for the two fitness components. Kolmogorov–Smirnov test, two-sided P < 0.001, n = 15,343. d, Patterns of conditional neutrality (light grey) and antagonistic pleiotropy (lime and green for transcripts beneficial for flowering success and fecundity, respectively) for gene expression under drought conditions. Black indicates transcripts that experienced selection in the same direction for both fitness components.
