摘要: A chromosomal region containing a hybrid sterility locus, S-1, from Oryza glaberrima, located on the short arm of chromosome 6, was investigated in 15 BC7F1 and one BC3F2 populations. As a gamete eliminator, S-1 induced both male and female gamete abortion and responded to typical, spherical, or empty pollen abortion when it was heterozygous. The gametes carrying S-1(a) (Oryza sativa allele in S-1) in the heterozygous S-1 locus had been eliminated in previous studies. We found here that both male and female gametes carrying the S-1(a) allele were killed incompletely in heterozygous ((S1S1a)-S-g) plants, with 26.22% female and 9.06% male gametes with the genotype remaining when the BC3F1 sterile plant produced male and female gametes, which fits with the hypothesis that the ratio of gametes of the female that were killed is higher than that of the male gametes. In addition, in sterile BC6F1 plants with the heterozygous S-1 locus, not only a majority of the female gametes carrying the S-1(a) allele, but also a quite number of those carrying the S-1(g) allele (O. glaberrima allele in S-1) could not be transmitted to their offspring. This abnormal transmission of female gametes illustrates the complexity of the reproductive isolation mechanism caused by S-1 and can not be explained by the 'one locus, sporo-gametal interaction' model alone. Interaction for female sterility between S-1 and two other loci on chromosomes 1 and 4 that suppress the expression of S-1 was identified. S-1 is the main reproductive isolation locus when mining favorable traits/genes from O. glaberrima due to its ubiquity between these two species, and the development of bridge parents carrying S-1 should be a useful method for overcoming or abating this obstacle between these two species. The chromosomal region of S may be the hot region of genetic diversity for speciation because several hybrid sterility loci between species, subspecies, and even intra-subspecies have been identified in the same region.
