Fig. 5From: Genome-wide identification and expression analysis of the polygalacturonase gene family in sweetpotato(a) Expression profiles of the IbPGs in different tissues with col scale. PE, RB, ISR, DE, RS, FR, Stem and Leaf represented different tissues of sweetpotato. (b) Expression profiles of the IbPGs in FR under different abiotic stresses and hormone treatments with row scale. All ratios were log2 transformed so that inductions and repressions of identical magnitude were numerically equal but opposite in sign. Red block indicated high relative expression levels and blue block indicated low relative expression levelsBack to article page
