First, we determined the chromosomal location of the S locus in Antirrhinum by fluorescence in situ hybridization of metaphase chromosomes of a self-incompatible line of S〓S〓 using an S〓 RNase gene and its corresponding 63kb BAC clone as probes, respectively.

玄参科植物金鱼草的自交不亲和性和茄科和蔷薇科类似，都属配子体自交不亲和植物，它们S位点都编码一类控制花柱自交不亲和性的核酸酶，称为S RNase。

The breaking parts of anthers in the four longerstamens were face to the reverse side of pistil and winding,but thedevelopments of the self-compatibility lines were regular.A greatdeal of callose was observed in stigma and pollen tuber both in theself-compatibility and self-incompatibility pollination.

对亲和性授粉和不亲和性授粉的荧光显微观察表明，无论是亲和性授粉还是不亲和性授粉，在柱头组织和花粉管组织中均可以形成大量的胼胝质，未发现胼胝质的产生和数量与自交不亲和性的识别反应有什么因果关系。

Also apiculus color segregated in three segregation populations, the further study on the relationship between spikelet fertility and apiculus color indicated that the average spikelet fertility of individuals with apiculus color was significantly higher than those without apiculus color, which implied the gene responsible for wide compatibility in Aiga should be linked with chromogen C.

进一步研究稃尖色的分离与育性的关系发现，在三个三交群体中，稃尖有色株的平均小穗育性都极显著地高于稃尖无色株，说明控制矮嘎的广亲和性基因与色素原基因C之间存在连锁关系，推测矮嘎中也带有广亲和基因Ss〓。

The conversion boundary of self-incompatibility was researched by sowing by stage. Sunshine of day and temperature was studied critically by investigating leafage and researching traits indoors. The results showed that the daily minimum temperature was the principal factor of affinity conversion and the affinity conversion boundary was 16.5~18.1℃.HE97 was primarily regard as self-incompatible line in this research. The method was by inbreeding and sib HE97, Half the silk of HE97 and Zheng58. Inbreeding and cross have been done simultaneously. The extending condition of pollen tube was observed by dying the silk after pollinating 4 hours. The individuals with pollen tube were observed having seeds, while the individuals without pollen tube were observed having few seeds or no seeds. So this study regard HE97 as sporophytic self-incompatibility .The planting ration of female parent HE97 and male parent 87-1 was 4:1.The nature cross-pollination was studied by the theory of endosperm xenity, the study show that the setting percentage of HE97 was 625%, in which the seed in self was 70% and the seed in hybrid was 30%. This was consistent with the study of silk anatomy structure, then come to the same conclusion: compatible pollen germination and fertilization can stimulate the self-incompatible pollen germination and fertilization in the same corn cob.

通过分期播种，进行了光温敏自交不亲和材料HE97亲和性转换区间的研究，依据田间跟踪调查叶龄及室内考种研究了HE97亲和性转换区间的光温临界值，结果表明：1日最低温度是影响HE97自交不亲和性的主要原因，亲和性转换区间在16.5℃～18.1℃之间。2通过HE97自交和姊妹交以及将HE97与郑58作为双亲，各自的花丝一分为二，分别正反交，授粉后4个小时分别取其花丝进行固定、染色，观察花粉管的伸长情况，根据结实率与花粉管伸长的对应关系，结果发现观察到花粉管的对应植株收获到了种子，而没有观察到花粉管的对应植株结实率极低或没有结实，本研究把HE97初步划为孢子体自交不亲和类型。3以HE97为母本，87-1为父本，按4母：1父行比，通过花粉直感效应研究天然异交率，结果母本HE97结实良好(62%)，其中自交粒占70%，异交粒占30%，结合花丝切片观察表明，亲和花粉的萌发及受精会导致落在同一果穗柱头上不亲和花粉的萌发不再受抑制。

Objective To observe the cellular mechanism of via skin infection of Microphage tropic HIV and further differentiate the infection of M-tropic and T-tropic HIV.

目的 观察巨噬细胞亲和性HIV经皮肤感染的细胞学机制，区别巨噬细胞亲和性及T细胞亲和性HIV感染的差异。

The Poaceae share a commom and special gametophytic self-incompatibility system, which is under the control of two unlinked loci: S and Z.

已报道自交不亲和禾本植物有着相同的自交不亲和系统，是一种特殊的配子体自交不亲和类型，和单一位点控制的自交不亲和性不同，其不亲和性由非连锁的两个复等位基因位点S和Z控制。

Currently, neither cloning S and Z gene nor identifying their products was successful. Phalaris coerulescens can be used as a model plant to study SI in the Poaceae. Segregating population and comparative genomics strategy were used to map S and Z, constructing high-resolution mapping of the target loci so that map base clone S and Z genes. It is a research orientation and hot spot of self-incompatibility in Poaceae.

目前S、Z基因的克隆和编码产物的鉴定均未有成功的报道，天蓝虉草可作为禾本自交不亲和性研究的一个模式作物，运用分离群体和比较基因组学方法构建S与Z位点的精细连锁图谱，以对自交不亲和基因进行图位克隆，是当前禾本科植物自交不亲和性研究的一个方向和热点。

Aimed at the arising problems such as the cross-incompatibility and hybrid's sterility during distant hybridization of fruit trees, effects of different treatments on cross-compatibility of distant hybridization in stone fruits were studied based on the former studies, then physiological and biochemical changes during hybridization between plum and apricot were primarily discussed, and rescue and culture system of hybrids' embryos were also conducted, further the genetic variation and principle between the hybrids and their parents were analyzed and methods of identification of hybrids were established.

针对果树远缘杂交过程中存在的杂交不亲和性及杂种不育性等问题，在前人研究的基础上，研究了不同处理对核果类果树远缘杂交亲和性的效应，并探讨了李、杏属间杂交过程中发生的生理生化变化以及花粉与柱头的互作，建立了李、杏属间远缘杂种的胚培养技术体系，建立了杂种鉴定检测方法，并分析了杂种后代与其父母本之间的遗传变异及规律，最终将一批远缘杂交新种质定植于大田，同时对自然界存在的杏梅种质资源进行了RAPD分析。

It showed that genes of self-incompatibility expresses during special term;③compatibility of selfing generation of variety with compatibility tend to decline.

具有自交不亲和性的品种，其自交不亲和性表现在特定的时期，说明控制自交不亲和的基因只在特定时期表达。

The sexual reproduction was controlled by the incompatibility factors The advances of researches on the mating characteristics, the composition and multiple alleles of incompatibility factors were summarized.
