Fig. 1From: Integrating genome-wide association study with transcriptomic data to predict candidate genes influencing Brassica napus root and biomass-related traits under low phosphorus conditionsCorrelation analysis of the investigated traits. a Correlations of studied traits under low phosphorus stress. The frequency distribution for each trait was displayed on the diagonal. The upper and lower parts represent the correlation coefficient and scatter plots between two diagonal traits, respectively. b Correlations of each investigated trait between control and low phosphorus stress. Red and blue indicate positive and negative correlations, respectively. ***, ** and * denote significance at the 0.1%, 1% and 5% levels of probability, respectivelyBack to article page
