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...
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 ...
in the present study, the diversity of trichoderma spp. was investigated in alkaline pistachio soils at different geographic area in kerman province, iran. a total of 161 trichoderma isolates were obtained and identified at the species level by analysis of their morphological characters and sequence analysis of their internal transcribed spacer regions of the rrna cluster and tef1 genes as phyl...
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...
genus trichoderma is a monophyletic fungus which some their species is known as biocontrol agent. this study was carried out for phylogenetic analysis of some isolates of the genus trichoderma. in this study 73 sequences (including 33 sequences from t. aspereluum, t. brevicompactum, t. capillare, t. harzianum, t. koningiopsis, t. pleuroticola and t. virens and 40 sequences obtained from geneban...
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...
Abstract The systematic position of the enigmatically mycoparasitic genus Squamanita ( Agaricales , Basidiomycota ) together with Cystoderma Phaeolepiota Floccularia and Leucopholiota is largely unknown. Recently they were recognized as Squamanitaceae but previous studies used few DNA markers from a restricted sample taxa family lacked formal taxonomic treatment. In this study, newly generated ...
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...
The strong overexpression or complete deletion of a gene gives only limited information about its control over a certain phenotype or pathway. Gene function studies based on these methods are therefore incomplete. To effect facile manipulation of gene expression across a full continuum of possible expression levels, we recently created a library of mutant promoters. Here, we provide the detaile...
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...
