克隆包含以拟南芥为寄主的甘蓝黑腐病菌Xcc1067无毒基因的DNA片段

A pLAFRl:: Tn5gusA5 transposon has been constructed that fuse the Escherichia coli gusA reporter gene on cosmid pLAFRl, it was used to mutagenize wild type of Xanthomonas campestris pv.

构建携带报告基因的转座子Ｔｎ５ｇｕｓＡ５于广谱性ｃｏｓ质粒ｐＬＡＦＲ１上，利用Ｔｎ５ｇｕｓＡ５诱变野生型甘蓝黑腐病黄单胞菌，筛选与致病性有关的因子（胞外多糖，胞外酶）突变体，通过Ｓｏｕｔｈｅｒｎ杂交和报告基因ｇｕｓ表达验证，突变体是由转座子诱变所致。

It has been shown that the extracellular protease I produced by Xanthomonas campestris pv.

甘蓝黑腐病黄单胞菌（ＸａｎｔｈｏｍｏｎａｓｃａｍｐｅｓｔｒｉｓＰｖ。

A recombinant plasmid PGXN3000 containing a cluster genes of regulation of pathogenicity factor (rpf genes) of Xoo, was introduced into strain 8476, a mutant of rpfA gene of Xanthomonas campestris pv.

通过三亲本接合的方法，将获得的含水稻白叶枯病黄单胞菌ｒｐｆ基因簇的重组质粒ｐＧＸＮ３０００导入甘蓝黑腐病黄单胞菌ｒｐｆＡ基因突变体８４７６中。

This evidence indicates that O.

用甜菜黑色焦枯病毒(Beet Black Scorch Virus,BBSV) 直接接种甜菜根,BBSV轻度侵染甜菜;而将BBSV与甘蓝油壶菌( Olpidium brassicae) 游动孢子体外混合接种甜菜根,BBSV 则严重侵染。

Using AFLP silver staining method, we isolated five DNA markers from a pair of nearisogenic cauliflower lines, four of which are linked to the cabbage black rot ( Xanthomonas campestris pv.

这意味着该标记可能与甘蓝黑腐病抗性基因紧密连锁。
