Fig. 5From: Identification of S23 causing both interspecific hybrid male sterility and environment-conditioned male sterility in riceExpression analysis of S23 candidate genes. The expression of ORF4 (a), ORF3 (b), ORF5 (c) and ORF2 (d) was analyzed in developing anthers from sporogenous cell stage to tricellular pollen stage and in other tissues including panicles, stems and leaves of HJX74, SSSL-S23 and HJX74/SSSL-S23 F1 plants in NSD.
