棉花枯萎菌(Fusarium oxysporum vasinfectum)单孢菌系间的遗传差异(英文)

Differentiation of monospore cultures within a isolate of Fusarium oxysporum vasinfectum

提取棉花枯萎菌ＣＦ３中的１５个单孢菌系基因组ＤＮＡ，用ＲＦＬＰ分析其遗传多样性，可以将１５个单孢菌系划分为２个杂交类型。致病性测定没有差异。对于１号和６号单孢菌系中新出现的ＤＮＡ片断的功能还需进一步证实。

Restriction fragment length polymorphism (RFLP) was undertaken to assess genetic diversification among 15 monospore cultures within a isolate of F. oxysporum vasinfectum. The 15 monospore cultures were categorized into 2 hybridization pattern types. The pathogenicity test on the varieties shown no difference within the 15 monospore cultures. The function of the new DNA fragments in culture No. 1 and No. 6 should be confirmed further.
