| 摘 要： | 本文研究了香蕉枯萎病菌4号生理小种湛江菌株(Foc 4-zj)产生的粗毒素对地衣芽胞杆菌R21菌株生长及其培养液中蛋白组成变化的影响。实验结果表明, Foc 4-zj的粗毒素能够抑制R21菌株的生长, 缩短其生长周期; 减少培养液上清蛋白含量以及改变蛋白质的种类; 低剂量的粗毒素有利于拮抗蛋白的积累, 而高剂量的粗毒素则相反。

| Abstract: | The effects of the crude toxin of Fusarium oxysporum f. sp. cubense race 4 (Foc 4-zj) on the growth of Bacillus licheniforms R21 strain and its protein secretion were studied. The results showed that the growth of R21 strain was inhibited by the crude toxin produced by Foc 4-zj, and its growth cycle was shorten. The protein contents were decreased and the kinds of protein in the supernatant fluid had changed significantly after treated with crude toxin. High dose of the crude toxin greatly decreased the contents of antagonistic proteins, whereas lower one increased. |
