Additional file 13: of Comparative transcriptome analysis reveals that tricarboxylic acid cycle-related genes are associated with maize CMS-C fertility restoration

(a)Tissue expression profile of 14 TCA cycle-related DEGs. The expression data (FPKM values) were obtained from qTeller ( www.qteller.com ). The FPKM values were log2 transformed (FPKM + 1), and a Z-score was calculated for each gene. (b) Comparison of TCA-related DEGs expression levels between the male-sterile line CHZS and its maintainer line HZS. A1, A2, and A3 denote developing anthers with the length of 1.5~ 2.0 mm (meiosis I), 2.0~ 2.5 mm (meiosis II) and 2.5~ 3.0 mm (uninucleate microspore) respectively. The data are given as means ± SEMs of at least three biological replicates. The relationship between maize pollen development stage and anther lenght can be found in another report [53]. (TIF 466 kb
