A mutant of Ustilago maydis (VR43) with single-gene resistance to the dicarboximide fungicide vinclozolin was previously isolated and characterized. A genomic library was constructed, and an 8.7-kb resistance-conferring fragment was isolated by sib selection. Sequencing this fragment, we identified an 1,218-bp open reading frame, which, if disrupted by deletion, no longer confers resistance. Analyses of the data in GenBank demonstrated a high degree of homology between the product of the 1,218-bp open reading frame, referred to as the adr-1 gene, and Ser (Thr) protein kinases.
先前已分离并鉴定出一种对二羧酰亚胺类杀菌剂乙烯菌核利具有单基因抗性的玉米黑粉菌突变体(VR43)。构建了一个基因组文库,并通过亚克隆筛选分离出一个8.7kb的抗性赋予片段。对该片段进行测序后,我们鉴定出一个1218bp的开放阅读框,如果通过缺失将其破坏,则不再赋予抗性。对GenBank中的数据进行分析表明,这个被称为adr-1基因的1218bp开放阅读框的产物与丝氨酸(苏氨酸)蛋白激酶之间具有高度同源性。
