  single conidial
Virulent single conidial isolates commonly produce a considerably higher percentage of A-type conidia than B-type conidia.
      
Contribution to host variation by genetic differences within the pathogens was thought to be minimal, since the inoculum of each pathogen traced to a single conidial colony of the original isolates.
      
Single conidial isolates of both types of conidia yield identical colonies, which then produced both types of conidia on agar media depending on temperature, thus showing that both types of conidia belong to the same fungus.
      
Plasmid loss and rearrangement were also observed within single conidial isolates derived from transformant 2539-T1-1 following ten asexual generations on non-selective agar medium.
      
Southern hybridization revealed rearrangements of integrated DNA in single conidial isolates of highcopy transformant 2539-T1-1 re-isolated from host plants, characterized by excision of one or more copies of the transforming plasmid.

Using a set of near-isogenic lines of wheat as differential hosts,weobserved the reaction of known resistant genes(Pm1—Pm4)to the localpathogen populations of different localities of Jiangsu Province.In Nanjing andHuaiyin powdery mildew nurseries of 1982,the reaction types of Pm1,Pm3band Pm3c,Pm 2 and Pm3a,as well as Pm4were respectively 3—4,0—3and0—1.The reaction types of Pm 4 recorded in these two nurseries wereslightly different.23 single pustule or single conidial chain samples isolated from Nanjingpathogen...

用小麦抗白粉病等基因系作鉴别寄主,观察了已知抗性基因(Pm1—Pm4)对江苏不同地区病原菌群体的反应。在1982年,南京和淮阴两地区病圃中,Pm1、Pm3b、Pm3c 反应型为3—4级。Pm2、Pm3a 为0—3级。Pm4 为0—1级,Pm4对两地病原菌群体的反应型略有差异。在温室中,用50ppm 苯并咪唑水溶液培养寄主离体叶片鉴定了从南京地区白粉病菌群体中分离的23个单孢或单孢子堆病菌标样。根据它们对寄主的侵染范围,可初步鉴定出6个致病力类型,并估计了病菌标样中与寄主抗性基因相对应的毒性基因的频率。从 Pm2、Pm4在我省及世界各地病圃中的抗性表现看,这两个抗性基因资源,对当前小麦抗白粉病育种是有效的,应首先加以利用。但是也应警惕 V_2和 V_4毒性基因的存在及其扩大的可能性。

The SEM photographs showed clearly that Paecilomyces odonatae Liu, Liang & Liu possessed twosorts of conidiogenous structures, which were the Paecilomyces-type with ellipsoidal conidia in chain andAcremonium-type producing cylindrical conidia in a slime head. The single spore strains obtained by single sporeisolation were used in morphological observahon and RAPD analysis. The resultS showed the cultural andmorphological characteristics and the bands of DNA RAPD of the ellipsoidal single conidial strains...
