Regulation of mating and pathogenic development in Ustilago maydis.
The plant pathogenic fungus Ustilago maydis induces disease only in its dikaryotic stage that is generated after mating. This process involves coordinated cAMP and mitogen-activated protein kinase signalling to regulate transcriptional as well as morphological responses. Among the induced products is the key regulator for pathogenic development. Recent advances identified crucial nodes that int...

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 کاملRole for RNA-binding proteins implicated in pathogenic development of Ustilago maydis.
Ustilago maydis causes smut disease on corn. Successful infection depends on a number of morphological transitions, such as pheromone-dependent formation of conjugation tubes and the switch to filamentous dikaryotic growth, as well as different types of mycelial structures during growth within the host plant. In order to address the involvement of RNA-binding proteins during this developmental ...
متن کاملCrosstalk between the unfolded protein response and pathways that regulate pathogenic development in Ustilago maydis.
The unfolded protein response (UPR) is a conserved eukaryotic signaling pathway regulating endoplasmic reticulum (ER) homeostasis during ER stress, which results, for example, from an increased demand for protein secretion. Here, we characterize the homologs of the central UPR regulatory proteins Hac1 (for Homologous to ATF/CREB1) and Inositol Requiring Enzyme1 in the plant pathogenic fungus Us...
