Fig. 9From: Comparative Transcriptome Combined with Morphophysiological Analyses Revealed Carotenoid Biosynthesis for Differential Chilling Tolerance in Two Contrasting Rice (Oryza sativa L.) GenotypesCorrelation between different indicators during greening in two rice genotypes under 17 and 26 °C. Slimmer and darker color of ellipse represents stronger correlation. The asterisks (*) indicate significant differences at p < 0.05. Detailed data and quantification methods for the indicators of thylakoid area per chloroplast and chloroplast circularity are described in Additional file 1: Fig. S1Back to article page
