Rice hybrid pollen fertility gene seatScAlleleSc-jWithSc-iSeparation gram Application grand and in breeding
Technical field
The present invention relates to field of plant genetic, in particular it relates to rice hybrid pollen fertility gene seatSc's AlleleSc-jWithSc-iSeparation clone and the application in breeding.
Background technology
Plant is hybridized by the hybridization between different cultivars.Hybrid has excellent in terms of growth potential, adaptability, yield Gesture, referred to as hybrid vigour.The yield, quality and resistance of crops can be improved using hybrid vigour.Asian Cultivated Rice is divided into Xian Rice subspecies(Oryza sativa ssp. indica)With japonica rice subspecies(O. sativa ssp. japonica), between them Hybrid has powerful hybrid vigour, and yield potential is very big.On the other hand, the breeding such as cultivated rice and wild rice hybridization and backcrossing is passed through Method, can will be present in some for example disease-resistant, pest-resistant, high yields of useful character of wild rice etc. and import cultivated rice, cultivate excellent New varieties.But, it is low or sterile to there is fertility in the hybrid that Hybrids of Indica and Japonica and cultivated rice and wild rice hybridization are produced Problem, referred to as hybrid dysgenesis (hybrid sterility).Described hybrid dysgenesis is produced in Oryza species atomization One of mechanism of reproduction isolation, belongs to reproduction after zygote and isolates(postzygotic reproductive isolation).It is miscellaneous Plant sterile phenomenon and seriously hinder the utilization that rice heterosis is converted into higher rice yield and the useful gene of wild rice.
There are multiple locus in paddy rice(loci)It is relevant with paddy rice hybrid fertility.Described locus is cytogenetics The concept of level, refers to a specific region of chromosome, may include the control homogeneity of the related gene of 1 or more than 1 Shape.In these hybrid fertile genes seat, some are to cause oogamete infertility, such asS5, S7, S8, S9, S15, S17, some It is to cause andro gamete(Pollen)Infertility, such asSa, Sb, Sc, Sd, Se, Sf (Kinoshita 1995, Rice Genet. Newsl., 12:9-15;1988, the Japan J. such as Ikehashi Breed. 38:283-291;Ikehashi etc. 1996, Rice Genet III, pp404-408;1996, the Theor Appl such as Wang Genet 92:183-190;Wang etc. 1998, Rice Genet Newsl 15:151-154;Zhang Guiquan etc. 1989, rice in China science 3:97-101;Zhang Guiquan etc. 1993, Acta Genetica Sinica 20:222-228;Zhang Guiquan etc. 1993, Acta Genetica Sinica 20:541-551;Zhang Guiquan etc. 1994, heredity Journal 21:34-41).These locus can have different degrees of variation point in different cultivars or strain or wild rice material Change, produce a variety of multiple alleles.According to the rice subspecies type and the effect to hybrid fertile for carrying these multiple alleles Should, they are divided into indica type(S-i), round-grained rice type(S-j), neutral type(S-n)Or other transitional types.Described gene symbolS Hybrid fertile gene seat is represented, such asSa, ScEtc. referring to specific hybrid dysgenesis locus,I, j, nRepresent respectively indica type(indica)、 Round-grained rice type(japonica)And neutral type (neutral)Multiple allelic loci, such asSc-iSc-jOrSc-n.Neutral type is also referred to as For affinity type(compatibility)Or wide affinity type(wide compatibility).
In paddy rice hybrid, the hybrid dysgenesis locus of differentiation tends to occur not affine interaction under heterozygous state, causes Carry the andro gamete of a certain allele(Or oogamete)Development is abnormal, and the allele specific of referred to as hybrid kills gamete (allele-specific gamete elimination)Effect.But, these locus are under homozygotic state(Such as homozygosis Parent)The normal development of gamete is not influenceed.The genetic behavior of most of hybrid dysgenesis locus meets " single seat position sporinite-match somebody with somebody The pattern (Oka, 1974, Genetics 77,521-534) of daughter interaction ".For example, with carrying respectivelySc-j/Sc-jGene The paddy rice japonica rice of type andSc-i/Sc-iThe NIL hybridization of genotype, the first generation of hybrid (F of generation1) genotype beSc- j/Sc-i.The andro gamete that its flower pesticide meiosis is produced(Pollen)In, carrySc-iAllele seat it is normal fertile, and carrySc-jThe male gametophyte development of allele is abnormal, therefore shows as about 50% infertility of pollen sterility i.e. half(Fig. 1).But hybrid is female The fertility of gamete is not influenceed by heterozygous genes seat.As a result the second generation of hybrid is caused(F2)Carried in colonySc-j/Sc-jBase Because the ratio of the plant of type is seriously on the low side, that is, deviateSc-i/Sc-iSc-i/Sc-jSc-j/Sc-j=1:2:1 Mendel point From rule(Fig. 1).
The clone of the Hybrid sterility between indica and japonica rice gene of 3 single seat positions is had reported at present, includingS5, Sa, HSA1(Chen etc. 2008,Proc. Natl. Acad. Sci. USA105, 11436-11441;Yang etc. 2012,Science337, 1336-1340;Long etc. 2008,Proc. Natl. Acad. Sci. USA105, 18871-18876;Kubo etc. 2016, Mol. Plant9, 221-232).
