Only one complete corollinae chromosome was detected in Ml4, and was determined corollinae chromosome 9. We have used in situ hybridization of genomic DNA to discrimination the parental chromosomes in Beta Ml 4, suppression of cross-hybridization by blocking DNA was not necessary indicating that the investigated Beta genome contain sufficient species-species DNA enabling the unequivocal determination of genomic composition of the hybrids.In our study , the results of BAC -FISH combined with the analysis of GISH in Beta M14,indicating that present of the corollinae chromosome 9 alone was sufficient to confer apospory in Beta M14 upon celluar and molecular..

The result ofpairwise Fst and Neutrality tests revealed significant genetic differentiation amongfour populations,and evolution of mtDNA COI gene incompliance with the Neutralitytheory.The genetic distance was the biggest between HEB and JXL,and was thesmallest between SDT and JXL among the 4 populations.

遗传多样性研究采用了线粒体DNA COI基因序列、RAPD和PCR-RFLP三种分子标记研究大猿叶甲4个地理种群的遗传结构和群体遗传多样性。1、对长约335bp的mtDNA COI片段进行序列分析，在4个群体64个个体中，共发现37个单倍型，总变异位点35个，多态位点29个，含量(63.68％)大于含量(36.32％)。4个地理种群的核苷酸多样性指数分别为，0.082、0.035、0.099、0.186。

A strain producing 2-oxoaldehyde reductase was isolated from LB culture medium containing methylglyoxal. By analyzing its physiological and biochemical characters, and 16S rDNA sequence, it was identified as S. maltophilia and named as Stenotrophomonas inaltophilia YL.

用含甲基乙二醛的LB培养基平板筛选到1株能代谢甲基乙二醛的细菌，通过对克隆到的16S rDNA基因序列比对及生理生化实验，将其鉴定为嗜麦芽寡养单胞菌，命名为Stenotrophomonas maltophilia YL。

The Arabidopsis CYP81F2 gene encodes a P450 monooxygenase that is essential for the pathogen-induced accumulation of 4-methoxyindol-3-ylmethyl glucosinolate, which in turn is activated by the atypical PEN2 myrosinase (a type of β-thioglucoside glucohydrolase) for antifungal defense.

拟南芥CYP81F2基因能都编码一种P450单加氧酶，这对4甲氧基-3二甲胺基芥子油甙的病原体诱导积累物是十分重要的。反过来，它也能被非典型PEN2黑芥子酶激活，以产生抗真菌的防御作用。

The method is based on a genetic model containing both the direct effects and maternal effects of an endosperm QTL and on an experimental design termed two-stage hierarchical design, in which the trait information is obtained from F3 endosperms and molecular marker information is obtained from F2 plants and F3 embryos.

文章提出了包括胚乳效应和母体效应的胚乳性状QTL定位的统计方法，该方法的实验设计是分子标记基因型信息来自F2母体植株和F3种子胚，胚乳性状表型值来自F3单粒种子胚乳，称之为两步等级设计。

These results suggest that the prescription reciped based on the theory of the correlation between spleen-stomach and mentality can effectively hold back the epileptogenesis. The antiepileptic mechanism of the prescription may relate with reducing the release of monoamines; regulating the level of cAMP and cGMP and diminishing gene and protein expression of c-fos、c-jun.

本文研究结果提示，根据脾胃与神志相关理论，以调理脾胃为主旨组成的复方能有效阻抗PTZ点燃大鼠EP发作；其抗痫机理可能与减少单胺类神经递质的释放、调节cAMP、cGMP水平，进而削弱c-fos、c-jun基因及蛋白的表达有关。

Using nanogram quantities on total RNA, the usage of dIVT protocol preserved about 70% information of gene expression when compared with those detected by the one-cycle T7 RNA linear amplification.
