Inbreeding levels of two Ustilago maydis populations.
Little is known about the population mating behavior of the smut fungus Ustilago maydis DC (Corda). To determine the amount of inbreeding that occurs in local U. maydis populations, two cornfields were sampled, one in North America (NA) at Le Sueur, Minnesota, and one in South America (SA) at Tarariras, Uruguay. These fields were chosen because of their geographic isolation and host management ...
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 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...
متن کاملcytology of ustilago maydis
cytology of ustialgo maydis teliospore, basidiospore and mycelium was investigated with epiflouresent microscope using both ethidium bromide and ocridin orange. surface sterilized teliospores were cultured on pda + 10% dextrose medium and incubated at 25ºc for 5 days. the results revealed that nucleus in teliospore occupied most of the inner part of its cell. sporidia had an ellipsoid shape nuc...
