The Agaricomycetidae is one of the most morphologically diverse clades of Basidiomycota that includes the well known Agaricales and Boletales, which are dominated by pileate-stipitate forms, and the more obscure Atheliales, which is a relatively small group of resupinate taxa. This study focused taxon sampling on resupinate forms that may be related to these groups, aimed at resolving the early...
Neonectria is a cosmopolitan genus and it is, in part, defined by its link to the anamorph genus Cylindrocarpon. Neonectria has been divided into informal groups on the basis of combined morphology of anamorph and teleomorph. Previously, Cylindrocarpon was divided into four groups defined by presence or absence of microconidia and chlamydospores. Molecular phylogenetic analyses have indicated t...
The Agaricomycotina contains about one-third of the described species of Fungi, including mushrooms, jelly fungi and basidiomycetous yeasts. Recent phylogenetic analyses by P. Matheny and colleagues combining nuclear rRNA genes with the protein-coding genes rpb1, rpb2 and tef1 support the division of Agaricomycotina into Tremellomycetes, Dacrymycetes and Agaricomycetes. There is strong support ...
A concatenated dataset of LSU, SSU, ITS and tef1 DNA sequence data was analysed to investigate the taxonomic position and phylogenetic relationships of the genus Camarosporium in Pleosporineae (Dothideomycetes). Newly generated sequences from camarosporium-like taxa collected from Europe (Italy) and Russia form a well-supported monophyletic clade within Pleosporineae. A new genus Camarosporidie...
Advances in synthetic biology and our understanding of the rules of promoter architecture have led to the development of diverse synthetic constitutive and inducible promoters in eukaryotes and prokaryotes. However, the design of promoters inducible by specific endogenous or environmental conditions is still rarely undertaken. In this study, we engineered and characterized a set of strong, synt...
Fusarium is a rapidly emerging, multidrug-resistant genus of fungal opportunists that was first identified in 1958 and is presently recognized in numerous cases of fusariosis each year. The authors examined trends in global Fusarium distribution, clinical presentation and prevalence since 1958 with the assumption that their distributions in each region had remained unaltered. The phylogeny and ...
tRNA precursors, which are transcribed by RNA polymerase III, undergo end-maturation, splicing, and base modifications. Hypomodified tRNAs, such as tRNA(Val(AAC)), lacking 7-methylguanosine and 5-methylcytidine modifications, are subject to degradation by a rapid tRNA decay pathway. Here we searched for genes which, when overexpressed, restored stability of tRNA(Val(AAC)) molecules in a modific...
هدف اصلی و اولیه این مطالعه, بهینه سازی انتقال ژن به قارچ بیماریزای گیاهی fusarium graminearum بود که عامل اصلی بیماری بلایت فوزاریومی سنبله (fhb) در غلات دانه ریز است. تراریخت کردن ژنتیکی، نه تنها ابزاری مفید جهت شناسایی ژنوم و مطالعه عملکرد آنها در بیمارگرهای گیاهی است, بلکه زمینه مطالعه برهمکنش گیاه - بیمارگر و راهکار لازم برای مقابله با بیماری را فراهم می کند. علاوه براین, تراریختی قارچ ها ...
The estimation of species diversity in fungal endophyte communities is based either on species counts or on the assignment of operational taxonomic units (OTUs). Consequently, the application of different species recognition criteria affects not only diversity estimates but also the ecological hypotheses that arise from those observations. The main objective of the study was to examine how the ...
The Gloeophyllales is a recently described order of Agaricomycotina containing a morphologically diverse array of polypores (Gloeophyllum), agarics (Neolentinus, Heliocybe) and resupinate fungi (VelutiVeluticeps, Boreostereum, Chaetodermella), most of which have been demonstrated to produce a brownrot mode of wood decay and are found preferentially on coniferous substrates. Multiple phylogeneti...
