Fig. 4From: Identification of fertility restoration candidate genes from a restorer line R186 for Gossypium harknessii cytoplasmic male sterile cottonIdentification of CMS-Rf candidate genes based on RNA-seq. a Volcanic map of R186_2 vs. 2074A_2. b Volcanic map of R186_2 vs. 2074B_2. c Determination of Rf candidate genes in BSA interval by venn diagram, based on gene expression in 2074A, 2074B and R186. d The heatmap for five candidate genes in the buds of 2074A, 2074B, and R186 at the early abortion stage and abortion stage. e The heatmap for four candidate genes in the buds of 2074A, 2074B, E5903, R144, and R245 at the early abortion stage and abortion stage. R186_2, the R186 buds with diameters of 1.5–9.0 mm (the stage of pollen abortion). 2074A_2, the 2074A buds with diameters of 1.5–9.0 mm (the stage of pollen abortion). 2074B_2, the 2074B buds with diameters of 1.5–9.0 mm (the stage of pollen abortion)Back to article page
