[Abstract]  The corn smut pathogen, Ustilago maydis (U. maydis) (DC.) Corda, is a semi-obligate plant pathogenic fungus in the phylum Basidiomycota (Alexopoulos et al., 1996). The fungus can be easily cultured in its haploid yeast phase on common laboratory media. However, to complete its sexual cycle U. maydis strictly requires its specific plant host, maize (Zea mays). The fungus is an interesting and important model organism for the study of the interactions of fungal biotrophic pathogens with plants. In this protocol, we describe the process of plant inoculation, teliospore recovery, germination, progeny isolation and initial mating type analysis. The primary purpose of this protocol is to identify individual progeny strains of U. maydis that can be ... [摘要]  科斯达(Corda)是在担子菌门(Basidiomycota)中的半必需的植物致病真菌(Alexopoulos等人)中的玉米黑斑病病原体( al。,1996)。真菌可以容易地在其单倍体酵母相中在普通实验室培养基上培养。然而,为了完成其性周期,U. maydis严格要求其特定的植物宿主,玉米( Zea mays )。真菌是研究真菌生物营养性病原体与植物相互作用的有趣和重要的模式生物体。在这个协议中,我们描述植物接种,冬孢子恢复,萌发,后代分离和初始交配型分析的过程。本协议的主要目的是鉴定个体的子代菌株。 maydis ,可用于下游遗传分析。生成目标突变体研究各种过程是这种和许多植物致病真菌的常见方法。通过有性杂交促进产生突变组合的能力,而不需要额外的选择性标记。

An Assay to Test the Capacity of Arabidopsis Plant Defensin Type1 Protein to Induce Cellular Zinc (Zn) Tolerance in Yeast

[Abstract]  Heterologous expression of genes in budding yeast Saccharomyces cerevisiae (S. cerevisiae) is especially suitable to functionally study the corresponding encoded protein at the cellular level (Bonneaud et al., 1991). This is mainly because many strains defective in specific activities are available and could be complemented by homologous genes existing across the eukaryotic kingdom (http://www.yeastgenome.org/). However, the protocol we describe here is not a complementation but a “gain-of-function” assay. It is based on a drop-test assay that we have set up to assess the cellular zinc tolerance conferred by the expression of heterologous genes in the wild-type S. cerevisiae. Different dilutions ... [摘要]  基因在出芽酵母酿酒酵母(酿酒酵母)中的异源表达特别适合于在细胞水平上功能性研究相应的编码蛋白质(Bonneaud等人, ,1991)。这主要是因为许多具有特异性活性缺陷的菌株是可获得的,并且可以通过真核生物界存在的同源基因来补充( http: /www.yeastgenome.org/)。然而,我们在这里描述的协议不是互补,而是"获得功能"测定。它是基于滴试验测定,我们已经设置以评估由异源基因在野生型S中的表达赋予的锌细胞耐受性。酿酒厂。将表达目的异源基因的酵母培养物的不同稀释液在一系列富锌平板上生长,然后与表达空载体的对照酵母进行比较。使用不同浓度的酵母和锌对于在酵母转化后成功描述锌耐受性表型是必要的(Mirouze等人,2006)。该试验也已经证明对于区分基因家族的相关成员是有价值的,如拟南芥属植物防御素类型1所例证的(Shahzad等人,2013)。
