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...
BLOCKIN 52 1. Cdk7-‐cyclin H-‐Mat1 kinase subcomplex of TFIIH is required for global transcription and mRNA turnover (I, II) BLOCKIN
Invasive aspergillosis (IA) due to Aspergillus fumigatus is a major cause of mortality in immunocompromised patients. The discovery of highly fertile strains of A. fumigatus opened the possibility to merge classical and contemporary genetics to address key questions about this pathogen. The merger involves sexual recombination, selection of desired traits, and genomics to identify any associate...
consistent with a one-ribonucleotide imprint; moreover, the authors do not attempt to detect molecules with a 5′ ′ end corresponding to a one-nucleotide gap. In addition, if the strand were broken due to hydrolysis of an RNA imprint, the 5′ ′ end would be devoid of any ribonucleotide(s); therefore, an RNase T2 control digestion (presented in the paper) is not expected to affect the outcome. Las...
PURPOSE CDK-activating kinase (CAK) is required for the regulation of the cell cycle and is a trimeric complex consisting of cyclin-dependent kinase 7 (CDK7), Cyclin H, and the accessory protein, MAT1. CDK7 also plays a critical role in regulating transcription, primarily by phosphorylating RNA polymerase II, as well as transcription factors such as estrogen receptor-α (ER). Deregulation of cel...
Eyespot, caused by the related fungal pathogens Oculimacula acuformis and O. yallundae, is an important cereal stem-base disease in temperate parts of world. Both species are dispersed mainly splash-dispersed conidia but also known to undergo sexual reproduction, yielding apothecia containing ascospores. Field diagnosis eyespot can be challenging, with other causing similar symptoms, which comp...
تعیین تنوع ژنتیکی قارچ جدا شده از روی علفهای هرز به کمک واکنش PCR که در دانستن نوترکیبیهای ژنتیکی احتمالی در جمعیتهای قارچ بسیار مفید خواهد بود، برای اولین بار در ایران انجام شد. جدایه های قارچ Magnaporthe grisea جدا شده از روی برخی علف های هرزگرامینه و برنج جهت تعیین تیپ آمیزشی به کمک واکنش PCR و تنوع ژنتیکی به کمک نشانگر RAPD-PCR مورد تجزیه و تحلیل قرار گرفت. با استفاده از سه آغازگر تصادفی ...

به منظور بر رسی احتمال وجود تیپهای آمیزشی فرم جنسی قارچ Mycosphaerella graminicola و پراکندگی و اهمیت آن در ایران از هفت استان کشور شامل استانهای مازندران، گلستان، خوزستان، فارس، اردبیل (مغان)، ایلام و کرمانشاه که کانونهای مهم بیماری بودند، در سال 1384 برگهای آلوده جمع آوری و 58 جدایه انتخاب و DNAی آنها استخراج شد. بررسی وجود تیپهای آمیزشی قارچ در ایران با استفاده از Multiplex PCR و دو ج...
