In this experiment, seedlings of arabidopsis thaliana ( col ) were observed after being treated by verlicillium dahliae ( vd - toxin ), exogenous salicylic acid ( sa ), nitric oxide donor ( snp ) and nitric oxide synthase inhibitor ( nna ), then we investigated the changes of endogenous h2o2 content, the activity of the antioxidant enzymes catalase ( cat, ec : 1. 11. 1. 6 ) and ascorbate peroxidase ( apx, ec : 1. 11. 1. 11 ) and mrna levels of cat3 in different stress conditions, we also identified the localizations of h2o2 and no accumulated in the leaves of arabidopsis

In recent years, the outbreak of nd appear some new characters, it is reported that the amount of immunity defeat on nd increased, even chicks with high hi titer can be infected by ndv virulent strain. the gene - engineering vaccine is badly needed to control nd outbreak. so newcastle disease virus strain b95, a naturally avirulent and heat stable strain, was introduced from australia
新城疫是國際獸疫局公布的16種烈性傳染病之一。近年來，新城疫的爆發出現了許多新特點，免疫失敗報道增多，甚至抗體水平較高的雞群也發病。為控制新城疫的爆發，急需研製
基因工程
苗。
Wild arabidopsis thaliana seeds were mutagenized with y - ray, and m2 populations were screened in the medium containing 200mmol / l nacl. 352 potential high - salt - tolerance mutants were selected from 80, 000 m2 seedlings, and 4 of this m2 mutants showed high - salt - tolerance in their m3 generation. this high - salt - tolerance mutants were backcrossed with the wild type arabidopsis thaliana
在含200mmol lnacl的改良ms培養
基上，通過對約80 ， 000株m _ 2代幼
苗的篩選，共獲得352株根仍表現向地性生長或真葉不變為褐色的植株作為可能的突變體。
( 2 ) gene flow frequency was reduced as distance from pollen donor increased and a dramatic reduction occurred at about 2 meters. the maximum distance where gene flow was not detected was 50 m for hybrid rice while it was 70 m for ms lines, with an exception that in one of the four ms lines it was detected a frequency of gene flow 2. 8 + 10 - 6 at 150 m for zhong 9a
在開花期主流風向ne的風速為0 . 2 ? 2 . 2m / sec的條件下， 2個雜交稻品種的最大漂流距離為40m ； 4個不育系的

基因漂流頻率均降為0 ，僅中9a在150m處發現了1株basta抗性
苗，經pcr檢測驗證為陽性。

Researches of schistosomiasis vaccines have gone more than 60 years, approximately including from the stages of dead vaccine and live vaccine ( irradiated attenuated cercariae vaccine ) to gene engineered vaccine, etc. many different forms of vaccines have been tested in animal models, including gluthathione s - transferase, paramyosin, irv - 5, triose phosphate isomerase, sm23, fatty acid binding protein ; which were considered promising by who / tdr. but none of them steadily accomplished the pre - set target level of 40 % protection. in order to enhance the protective capacity further, it is essential to develop novel vaccine antigens and / or vaccine adjuvants
血吸蟲病疫
苗研究已有60多年的歷史，大致經歷了死疫
苗、活疫
苗（照射致弱尾蚴疫
苗）和
基因工程疫
苗等研究階段，產生了一些who / tdr推薦認為很有希望的疫
苗候選分子，如谷胱甘肽- s -轉移酶（ gst ） 、副肌球蛋白（ sm97 ） 、照射致弱疫
苗抗原5 （ irv - 5 ） 、磷酸丙糖異構酶（ tpi ） 、曼氏血吸蟲膜內在蛋白（ sm23 ）和脂肪酸結合蛋白（ fabp ， sm14 ）等，但其對宿主的保護作用均不甚理想，未能穩定地達到40或以上的保護力水平，因此有必要繼續尋找新的疫
苗抗原分子和/或疫
苗佐劑，進一步提高其保護力。
