Through single hyphal-tip isolation,a heterokaryon,Ag149,was obtained,and its two different phenotypic segregants,Ag149-Ⅰ and Ag149-Ⅲ,were separated from the mutated sectors on colony of the heterokaryon.

采用銀染mRNA差異顯示技術 ,研究了棉花枯萎病菌異核體菌株 (Ag14 9)及其兩個不同表型分離子(Ag14 9 Ⅰ和Ag14 9 Ⅲ )之間差異表達的基因 ,觀察到在 3 0 0～ 70 0bp之間出現了 19個差異條帶 ,經反向RNA印跡 ,證實其中 2條差異帶為陽性 :編號為C6的差異條帶在Ag14 9和Ag14 9 Ⅰ菌株中呈高表達 ,而編號為G5的差異條帶在菌株Ag14 9和Ag14 9 Ⅲ中呈高表達。

Then,those strains were mutated,re-isolated,and identified into 7 nit mutant strains which were veg- etably compatible and form heterokaryon.

從蟬擬青霉T-1上分離獲得的6個單孢子菌株,經過誘發、分離、鑒定,保存了7個nit突變株,并通過營養親和試驗篩選出蟬擬青霉異核體菌株55-57、56-57、58-57,以及穩定性好的親本菌株55、56、57、58,比較分析各菌株對蚜蟲的致病力以及胞外多糖的含量,數據顯示55-57、56-57、58-57菌株的LT50、LT90較低,而且它們的胞外多糖含量穩定且高于55、56、57、58各親本菌株。
