The Cdk7/cyclin H/ménage-à-trois 1 (MAT1) heterotrimer has proposed functions in transcription as the kinase component of basal transcription factor TFIIH and is activated in adult hearts by Gq-, calcineurin-, and biomechanical stress-dependent pathways for hypertrophic growth. Using cardiac-specific Cre, we have ablated MAT1 in myocardium. Despite reduced Cdk7 activity, MAT1-deficient hearts g...
جو یکی از غلات مهم جهان است که به عنوان غذا مورد استفاده بشر و حیوانات قرار می گیرد. بیماری اسکالد جو که توسط قارچ rhynchosporium commune ایجاد میشود، یکی از مخربترین بیماری¬های جو در مناطق با شرایط آب و هوایی خنک و مرطوب می باشد. میزان کاهش محصول در اثر این بیماری بین 10 الی 45 درصد گزارش شده است. اگرچه تاکنون وقوع مرحله جنسی این قارچ در طبیعت و بررسی های متعدد مشاهده نشده است اما تنوع ژنتیکی ...
We have assessed the distribution and mating type of chickpea blight (Didymella rabiei (Kov.) v. Arx) from a total 350 272 fields in major (Cicer arietinum L.) growing areas Ethiopia for two consecutive cropping seasons 2017 2018, respectively. The prevalence D. was 20 % year 7% 2018. Severity range 2?9 incidence 10–100 were recorded both only 7–20 assed fields. Field 2018 significantly differe...
Fusarium graminearum, the causal agent of Fusarium head blight in cereal crops, produces sexual progeny (ascospore) as an important overwintering and dissemination strategy for completing the disease cycle. This homothallic ascomycetous species does not require a partner for sexual mating; instead, it carries two opposite mating-type (MAT) loci in a single nucleus to control sexual development....

Verticillium dahliae is a cosmopolitan, soilborne fungus that causes a significant wilt disease on a wide variety of plant hosts including economically important crops, ornamentals, and timber species. Clonal expansion through asexual reproduction plays a vital role in recurring plant epidemics caused by this pathogen. The recent discovery of recombination between clonal lineages and preliminar...
SUMMARY Idiomorphs mat1-1 and mat1-2 from Mycosphaerella fijiensis, the causal agent of black leaf streak disease of banana, were isolated. Degenerate oligos were used to amplify the HMG box of the mat1-2 idiomorph from M. fijiensis, showing homology with the HMG box of Mycosphaerella graminicola. Using a DNA walking strategy, anchored on the DNA lyase gene towards the HMG box, a 9-kb-long regi...
Leptographium procerum and the closely related species Leptographium profanum, are ascomycetes associated with root-infesting beetles on pines and hardwood trees, respectively. Both species occur in North America where they are apparently native. L. procerum has also been found in Europe, China New Zealand, and South Africa where it has most probably been introduced. As is true for many other L...
Gibberella zeae, a self-fertile, haploid filamentous ascomycete, causes serious epidemics of wheat (Triticum aestivum) head blight worldwide and contaminates grain with trichothecene mycotoxins. Anecdotal evidence dating back to the late 19th century indicates that G. zeae ascospores (sexual spores) are a more important inoculum source than are macroconidia (asexual spores), although the fungus...
