| 摘 要： | 带有硝酸盐利用缺陷型遗传标记的大丽轮技菌Verticilliumdahliae黑色菌核型和白色菌丝型菌株在25℃下配对培养,形成野生型融合菌落带,对融合带的分生孢子后代进行遗传分析的结果表明,融合带中的异核体表现不稳定,分布不均匀。微菌核遗传因子可随亲本细胞质在异核体中的运动和交换而发生迁移。

| Abstract: | Heterokaryons are produced by pairing culture between microsclerotia forming strains and no microscleroha forming mutants of Verticillium dahliae using nitrate-nonutilizing phenotype as marker. The descendants from heterokaryon were tested. The results suggested that the formed heterokaryons were tmstable and scattered unregulary. Controlling factors of microsclerotia formation could migrate withcytoplasmic moving between fungal cells. |
