The transgenic tobacco plants could delay TMV infection for about 25 days compared with non-transgenic tobacco plants.Pokeweed antiviral protein II is expressed with high level in summer leaves. The expression of PAPII is regulated by season. The total RNA was extracted from pokeweed (Phytolacca americana L.) leaves in summer using the method of TRIzol and used as template to amplify the PAPII gene by RT-PCR and then the gene was cloned into E.coli expression vector and secreted expression pPIC9K vector. The two vectors with PAPII gene were then transferred into E.coli strain BL21 (DE3)-plysS and Pachia pastor is GS115 strain respectively. The specific protein was produced induced by IPTG and methanol.

由于美洲商陆抗病毒蛋白Ⅱ是一个受季节调控表达的蛋白，本实验以美洲商陆夏季叶片为材料，通过对其总RNA的提取、反转录、并用PAPⅡ的特异引物进行PCR扩增，对PAPⅡ进行了基因克隆、序列分析，结果扩增出来的PAPⅡ基因与已经报道的序列同源性是99.9％，然后将该基因构建到原核、真核表达载体上，分别转化了大肠杆菌和毕赤酵母并对它们进行了诱导表达，在两个表达系统中均获得了有活性的PAPⅡ表达蛋白，体外生物测定表明表达的蛋白均具有抑制病毒的活性，PAPⅡ基因在酵母中还没有表达的报道，这为获得具活性PAPⅡ蛋白提供了一种简便可行的方法。

The DGCMS plants were complete sterile at the both temperature situations, and there was no pollen sac differentiation and had smaller petals and stamens at the higher temperature situation, but there were 1～4 pollen sacs in each anther and had bigger petals and stamens at the lower temperature situation. The cytological characteristics of the anther development were the same as that of GMS plants in Yi-3AB.

表现质核不育的植株，在高温条件下，花瓣小，表现彻底的pol CMS不育，无花粉囊的分化，在低温条件下，花瓣变大，也表现彻底雄性不育，具有核、质不育的共同特点，每个花药可分化出1～4个花粉囊，但无可育花粉，其雄性败育时期和特点与宜3A相同。

Were investigated in pot culture under three water treatments: well watered , middle drought treatment and serious drought treatment .The contents of malondialdehyde and soluble sugar, superoxide dismutase, catalase, peroxide dismutase, polyphone oxidase and ascorbic acid peroxidase activities were compared between plants infected with Glomus mosseae and those not infected (Non-AM plants) at different water-treatments.

The results show that the tiller number, biomass accumulation, contents of soluble sugar and proline, and activity of SOD isozyme of E+ plants were significantly higher (P.05), but malondialdehyde content significantly lower (P.05), than those of F- plants. In conclusion, endophyte infection improved the salt tolerance of wild barley under outside pot conditions.

结果表明：在高盐浓度300 mmol L^(-1下内生真菌显著提高了宿主野大麦分蘖能力、生物量积累、可溶性糖含量、脯氨酸含量、SOD酶活性(P.05)，同时降低了丙二醛含量，说明内生真菌的侵入有利于提高宿主野大麦在室外盆栽条件下的耐盐性。
