Fig. 1From: 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 ricePollen sterility caused by the interaction of different pollen sterility loci. a Pollen phenotypes of Taichung65-4×. b Pollens of a hybrid with interaction at Sa locus. c Pollens of a hybrid with interaction at Sb locus. d Pollens of a hybrid with interaction at Sc locus. e Pollens of a hybrid with double loci (SaSb) interaction. f Pollens of a hybrid with triple loci (SaSbSc) interaction. g Pollens of a hybrid (T449-4× × E1-4×) with no-interaction at Sa and Sb pollen sterility loci, but interaction exists at Sc pollen sterility locus. h Pollens of a hybrid (T449-4× × E24-4×) with no-interaction at Sa and Sb pollen sterility loci, but interaction exists at Sc pollen sterility locus. i Pollens of a hybrid (T449-4× × E24-4×), with no-interaction at Sa, Sb and Sc pollen sterility loci.
