Fig. 4From: Pervasive interactions of Sa and Sb loci cause high pollen sterility and abrupt changes in gene expression during meiosis that could be overcome by double neutral genes in autotetraploid riceDifferentially expressed genes in four comparison groups. a Number of differentially expressed genes in four groups. Genes were divided into up- and down-regulated if their expression levels increased and decreased at least two-fold (P < 0.05), respectively. b Venn diagram of differentially expressed genes in four groups. c Expression patterns of different groups in autotetraploid rice hybrids. Red and green colors indicate up- and down-regulated genes, respectivelyBack to article page
