Characterization of the Largest Effector Gene Cluster of Ustilago maydis
In the genome of the biotrophic plant pathogen Ustilago maydis, many of the genes coding for secreted protein effectors modulating virulence are arranged in gene clusters. The vast majority of these genes encode novel proteins whose expression is coupled to plant colonization. The largest of these gene clusters, cluster 19A, encodes 24 secreted effectors. Deletion of the entire cluster results ...
متن کاملسیتولوژی Ustilago maydis
رفتار هسته در تلیوسپور، بازیدیوسپور و میسلیومهای Ustilago maydis مورد بررسی قرار گرفت. جهت کشت تلیوسپورها از محیط PDA + 10% دکستروز استفاده گردید. مطالعه رفتار هسته با استفاده از میکروسکوپ اپیفلورسنت و رنگآمیزی با دو رنگ اتیدیوم برماید و اکردین اورنج صورت پذیرفت. هسته در تلیوسپور کروی و بزرگ و اکثر فضای داخلی آن را اشغال نموده است. بازیدیوسپورها (اسپوریدیوم) به صورت غیرانگلی و به روش جوانهز...
متن کاملGlycolysis in Ustilago maydis.
The kinetic parameters of the 10 glycolytic enzymes and glycolytic fluxes were determined for the first time in Ustilago maydis. Enzyme activities in yeast grown in minimal medium and harvested in the stationary stage were twofold higher than those from yeast grown in rich medium. In contrast, in yeast harvested in the exponential stage, the enzyme activities were higher in cells grown in rich ...
متن کاملIdentification of a gene cluster for biosynthesis of mannosylerythritol lipids in the basidiomycetous fungus Ustilago maydis.
Many microorganisms produce surface-active substances that enhance the availability of water-insoluble substrates. Although many of these biosurfactants have interesting potential applications, very little is known about their biosynthesis. The basidiomycetous fungus Ustilago maydis secretes large amounts of mannosylerythritol lipids (MELs) under conditions of nitrogen starvation. We recently d...
متن کاملUstilago maydis as a Pathogen.
The Ustilago maydis-maize pathosystem has emerged as the current model for plant pathogenic basidiomycetes and as one of the few models for a true biotrophic interaction that persists throughout fungal development inside the host plant. This is based on the highly advanced genetic system for both the pathogen and its host, the ability to propagate U. maydis in axenic culture, and its unique cap...
