The diversity of Trichoderma spp. was investigated in alkaline soils of pistachio orchards at different geographic areas in Kerman province, Iran. A total of 161 Trichoderma isolates were obtained and identified at the species level by their morphological characters and sequence analysis of their internal transcribed spacer (ITS) and tef1-α genomic regions. Totally, five species of Trichoderma ...
جنس Trichodermaاز مهمترین جنسهای قارچی در زمینه کنترل بیولوژیک بیماریهای گیاهی، افزایش رشد و القای مقاومت در گیاهان به شمار میرود. ارتباط فیلوژنتیکی 81 جدایه متعلق به شش گونه از این جنس (شامل چند جدایه بیوکنترل امید بخش) که از مزارع برنج استان مازندران به دست آمدهاند، بر اساس توالی قطعهای از ژن αtef1بررسی شد. توالیهای ژن مذکور در جدایههای مورد آزمایش به همراه توالیه...
UNLABELLED The morphological concept of Penicillium sclerotiorum (subgenus Aspergilloides) includes strains with monoverticillate, vesiculate conidiophores, and vivid orange to red colony colours, with colourful sclerotia sometimes produced. Multigene phylogenetic analyses with the nuclear ribosomal internal transcribed spacer (ITS) region, cytochrome c oxidase subunit 1 (cox1), β-tubulin (benA...
در جریان بازدید از شالیزارهای برنج استانهای فارس و خوزستان در مرحلۀ سفت شدن دانه، 42 نمونه بذر گردآوری شد. برای جداسازی Fusariumاز نمونهها، بذرها روی محیط غذایی اختصاصی فوزاریوم (Pepton-PCNB-Agar, PPA) به دو روش ضدعفونی با محلول هیپوکلریت سدیم 1درصد و بدون ضدعفونی کشت و در انکوباتور (اتاقک رشد) با دمای 1±25 درجۀ سلسیوس و نور متناوب (روشنایی و تاریکی) نگهداری شدند. 26 جدایه بر اساس ویژگی‌های...
Nigroboletus is proposed as a novel genus in family Boletaceae, subfamily Boletoideae, to include N. roseonigrescens, a new boletoid species from tropical environment in south-eastern China. Detailed morphological description, color pictures of both fresh basidiomes in habitat and dried material along with photomicrographs and line drawings of the main anatomical features are provided, supporte...
Abstract Wilt disease with unknown etiology causes mass mortality in commercial Acacia mangium nurseries South Sumatra. This pathogen induces symptoms of chlorosis the lower leaves and develops into shoots; subsequently, plants wither die. research identifies pathogenic species causing this wilt to assess its pathogenicity or virulence. Fifteen isolates Fusarium oxysporum varying colony sizes c...
Abstract Peppermint is an important medicinal plant, and it known for its essential oils phenolic acids. Verticillium wilt a vascular disease resulted from several spp. causing significant economic losses in peppermint cultivation. In this study, the fungus Gibellulopsis nigrescens (syn. ) was isolated symptomless plants during regular control of on Germany. A pure fungal culture prepared, DNA ...
In this study, we introduce a new species Nigrograna wuhanensis, which was collected from Camellia japonica in Hubei Province, China. The established based on morphological characteristics and multi-locus phylogenetic analysis of combined SSU, LSU, ITS tef1-α sequence data. wuhanensis is characterized by scattered, immersed ascomata with long neck superfi cial the substrate, clavate short pedic...
A phylogeny of the fungal phylum Basidiomycota is presented based on a survey of 160 taxa and five nuclear genes. Two genes, rpb2, and tef1, are presented in detail. The rpb2 gene is more variable than tef1 and recovers well-supported clades at shallow and deep taxonomic levels. The tef1 gene recovers some deep and ordinal-level relationships but with greater branch support from nucleotides com...
Sustainability of nutrient requirements for microbial proliferation on a large scale is a challenge in bioremediation processes. This article presents data on biochemical properties of a free cyanide resistant and total nitrogen assimilating fungal isolate from the rhizosphere of Zeamays (maize) growing in soil contaminated with a cyanide-based pesticide. DNA extracted from this isolate were PC...
