Black truffles that morphologically resemble Tuber indicum have been known to occur in Japan since 1979. Our previous studies showed that there are two phylotypes of these truffles, both of which fell into the T. indicum complex (hereinafter "Tuber sp. 6" and "Tuber sp. 7"). However, their taxonomic treatment is still unclear. In this study, we conducted morphological and phylogenetic analyses ...

Identification of fungi and the International Code of Nomenclature underpinning this process, rests strongly on the characterisation of morphological structures. Yet, the value of these characters to define species in many groups has become questionable or even superfluous. This has emerged as DNA-based techniques have increasingly revealed cryptic species and species complexes. This problem is...

One gene coding for yeast cytoplasmic elongation factor 1 alpha (EF-1 alpha) was isolated by colony hybridization using a cDNA probe prepared from purified EF-1 alpha mRNA. A recombinant plasmid, pLB1, with a 6-kilobase yeast DNA insert, was found by hybrid selection and translation experiments to carry the entire gene. The nucleotide sequence of the gene with its 5'- and 3'-flanking regions wa...

Species in Phellinus s.s. are some of the most important wood-decaying fungal pathogens in northern temperate forests, yet data on species incidence in North America remains limited. Therefore, phylogenetic analyses were performed using four loci (ITS, nLSU, tef1 and rpb2) with isolates representing 13 species. Results of phylogenetic analyses using maximum likelihood and Bayesian inference rev...

Diaporthe ampelina (=Phomopsis viticola) is one of the most important pathogens causing both cane/leaf spot and wood canker diseases in grape growing countries world. In this research, morphological, molecular pathogenic characterization 23 D. isolates were studied their sensitivity tested against hot-water treatments some fungicides used vineyards. Morphologically, grouped according to “W type...

Pine needle diseases, such as red band and brown spot blight, are serious pine diseases that threatens forests in many countries. Several outbreaks have been reported resulting loss of productivity mortality both exotic native plantations Pinus spp. Symptomatology these two is quite similar characterized by the appearance yellowish areas/bands on hosts’ leaves subsequently lead to more extensiv...

The genus Septoria includes important plant pathogens with worldwide distribution, commonly associated with leaf spots and stem cankers of a broad range of plant hosts. In this study, eight isolates of Septoria were recovered from leaves with leaf spot on four herbaceous and woody plants from Gilan, Ardebil, East and West Azerbaijan provinces in north and northwest of Iran. The isolates were st...

The purpose of this study was to identify the Fusarium species associated with selected medicinal plant species of Lamiaceae and Asteraceae in Kerman, the second-largest province of Iran. The plants showing wilting/rotting symptoms as well as asymptomatic plants were collected from main medicinal plants reservoirs and production areas. Fusarium species were identified based on...
