The genus Cercospora consists of numerous important, apparently asexual plant pathogens. We designed degenerate primers from homologous sequences in related species to amplify part of the C. apii, C. apiicola, C. beticola, C. zeae-maydis and C. zeina mating type genes. Chromosome walking was used to determine the full length mating type genes of these species. Primers were developed to amplify ...
Mating-type switching in Schizosaccharomyces pombe involves replacing genetic information at the expressed mat1 locus with sequences copied from one of two silent donor loci, mat2-P or mat3-M, located within a 20-kb heterochromatic domain. Donor selection is dictated by cell type: mat2 is the preferred donor in M cells, and mat3 is the preferred donor in P cells. Here we show that a recombinati...
The formation of propagules is the critical stage for transmission pathogenic fungus Stemphylium eturmiunum. However, how development these regulated remains to be fully understood. Here, we show that nitric oxide (NO) necessary reproduction in S. eturmiunum.Application NO scavenger carboxy-CPTIO (cPTIO) or soluble guanylate cyclase (sGC) inhibitor NS-2028 abolishes formation, which was increas...
قارچ Pyricularia oryzae عامل بیماری بلاست برنج و گندم و لکه برگی روی تعدادی از گیاهان گرامینهای است. بیماری بلاست یکی از مهمترین بیماریهای برنج در اکثر مناطق برنج‌خیز ایران به شمار می‌رود که معمولا سالانه خسارت اقتصادی قابل توجهی روی برنج ایجاد می‌کند. در تابستان سالهای 1393 و 1395 از مزارع برنج، ذرت، وعلف‌های هرز باغات مرکبات و جنگلهای نواحی جنوبی دریای خزر و مزارع برنج استان خراس...
TFIIH is a multiprotein complex required for both transcription and DNA repair. Single particles of human TFIIH were revealed by electron microscopy and image processing at a resolution of 3.8 nm. TFIIH is 16 x 12.5 x 7.5 nm in size and is organized into a ring-like structure from which a large protein domain protrudes out. A subcomplex assembled from five recombinant core subunits also forms a...
Penicillium chrysogenum is a filamentous fungus of major medical and historical importance, being the original and present-day industrial source of the antibiotic penicillin. The species has been considered asexual for more than 100 y, and despite concerted efforts, it has not been possible to induce sexual reproduction, which has prevented sexual crosses being used for strain improvement. Howe...
