Antimycin A-resistant respiratory pathway in Ustilago maydis and Neurospora sitophila.

Antimycin A-resistant respiratory pathway in Ustilago maydis and Neurospora sitophila.

Heterokaryosis in Neurospora sitophila.

ETEROKARYOSIS has been extensively used as a major tool in formal genetic analysis of both Mendelian and non-Mendelian genes and in establishing gene-enzyme relationships. So far it is the only way to perform genetic anslysis of somatic cells in tissue culture (EPHRUSSI 1965; MINTZ and BAKER 1967). These aspects of heterokaryosis have been reviewed elsewhere ( JINKS 1965; FINCHAM 1966; DAVIS 19...

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...

Glycolysis 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 ...

Ustilago 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...
