Pathogen - resistant Transgenic Plant from Dwarfing Rootstock of Cherry by Introducing Antibacterial Polypeptide Genes 抗菌肽基因转化樱桃矮化砧木获得抗根瘤病的转基因植株
Therefore, we carried on the researches on pathogen biological characters and resistant mechanism of apple to apple scab, the main results were obtained as follows. 因此,为了摸清陕西省苹果黑星病的发生危害特点和流行规律,本文就陕西苹果黑星病菌形态学特性、致病性分化以及寄主品种的抗病性进行了研究,取得了以下主要结果。
AIM : Staphylococcus aureus is a common pathogen causing serious hospital infections and community acquired infections and is also the pathogen with the highest drug resistant incidence. 目的:金黄色葡萄球菌是社区获得感染(CAI)和医院内感染(HI)最为常见的致病菌,也是耐药发生率最高的致病菌。
Experiment with correlation of non pathogen elements and rice blast resistant change 非病原因素与水稻抗瘟性变化的相关性调查初报
After inoculating citrus with the pathogen, the PAL activities in resistant types rose sharply to a peak. The relationships between the resistance of citrus to P.parasitica and PO, PO isoenzyme and PPO were also studied. 接种后抗性类型PAL活性急剧升高,并很快出现峰值,而感病类型的PAL活性则升高缓慢,且峰值低,还研究了PO、PPO活性及PO同工酶与柑桔抗病性的关系。
