[Abstract]  Fusarium graminearum is a destructive phytopathogen that infects major cereal crops such as wheat, maize and barley. Double or triple mutants are often very useful in the phenotypic and genetic analysis of genes that function redundantly or within similar pathways. When single gene mutants are available, double or triple mutants can be generated by crossing heterothallic strains or multiple rounds of protoplast transformation. When individual mutants carry different antibiotic resistance, it is convenient to use the sexual crossing to generate desired recombinant strains. Here, we present a protocol for generating double or triple mutants by sexual crossing in one homothallic strain with further antibiotic resistance and genomic DNA PCR screening of recombinant progenies. [摘要]  禾谷镰刀菌(Fusarium graminearum)是一种破坏性的植物病原体,可感染小麦,玉米和大麦等主要谷类作物。 双重或三重突变体通常在冗余或相似途径内起作用的基因的表型和遗传分析中非常有用。 当可获得单基因突变体时,可通过杂交异源菌株或多轮原生质体转化产生双突变体或三突变体。 当单个突变体携带不同的抗生素抗性时,使用有性杂交方便产生所需的重组菌株是方便的。 在这里,我们提出了一种方案,通过在一个同源的菌株中通过有性杂交产生双突变体或三突变体,具有进一步的抗生素抗性和重组后代的基因组DNA PCR筛选。

【背景】子囊菌真菌镰刀菌(Fusarium graminearum)是一种破坏性的植物病原体,可引起谷类食物的头部枯萎病,穗腐病,茎腐病和冠。它可以在胡萝卜琼脂体外产生perithecia 。该测定法可用于研究子囊膜发育,子囊孢子放电和性重组(Nicholson,2007)。

F。禾本科植物是同源的,具有MAT1-1和MAT1-2-1基因座;这些基因座缺失突变体中的每一个在自交中都是无菌的(Zheng et al。,2013)。为了产生双基因突变体,一个单基因突变体传统上与 MAT 缺失突变体杂交,并进一步与另一个突变体杂交(Bowden和Leslie,1999; Lee et al。 ,2011; Son et ...
