This paper summarized the experiments which support or negate the existence of female sterility,analyzed the experimental ideas and inference methods of these experiments,especially Sano' s;and concluded that the conclusion that the hybrid sterility is only caused by male or female sterility is a one - sided view,therefore attention should be paid to the genetics of both female and male sterility.
本文对证明水稻亚种间杂种存在和不存在雌性不育的研究进行了综述与分析,从中可以看出无论是认为水稻亚种间杂种不育性表现为雄性不育还是雌性不育的结论都有一定的片面性;尤其是Sano证明基因座S-5不存在的研究存在较大的缺陷。因此,水稻亚种间杂种雌雄配子败育对小穗育性影响的大小有待进一步研究。

They all contain 13 protein coding gene,2 rRNA gene,22 tRNA gene and 1 D-Loop.The base composition for the four nucleotides is A-32.0%,C-27.6%,G-14.7%,T-25.8%,And it is A-32.5%,C-26.9%,G-14.1%,T-26.5%for Yellow-throated Marten.But there are some definite differences in base composition,the using of Initiation codon and Stop codon,and the mode of repeat sequences in control region.The codon usages of Manes have bias,and the ttiird locations of codon of protein-coding genes have the higher frequency in using A and C.There may be some relativity with the content of A and C in D-loop,namely,it has relation with the mode of repeat sequences.The complete mitochondrial genome of the Sable and Yellow-throated Marten were submitted to GenBank,and the accession number are FJ429093 and FJ719367 respectively.3、The complete mitochondrial genome of 6 other species of Mustelidae from GenBank and some sequences of D-loop from the 6 species were aligned.
