سیتولوژی 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 کاملGenetic analysis of biosurfactant production in Ustilago maydis.
The dimorphic basidiomycete Ustilago maydis produces large amounts of surface-active compounds under conditions of nitrogen starvation. These biosurfactants consist of derivatives of two classes of amphipathic glycolipids. Ustilagic acids are cellobiose lipids in which the disaccharide is O-glycosidically linked to 15,16-dihydroxyhexadecanoic acid. Ustilipids are mannosylerythritol lipids deriv...
متن کاملOrganization of chromosome ends in Ustilago maydis. RecQ-like helicase motifs at telomeric regions.
In this study we have established the structure of chromosome ends in the basidiomycete fungus Ustilago maydis. We isolated and characterized several clones containing telomeric regions and found that as in other organisms, they consist of middle repeated DNA sequences. Two principal types of sequence were found: UTASa was highly conserved in nucleotide sequence and located almost exclusively a...
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...
