Fusarium wilt of melon is a destructive fungal disease throughout the world. In this study, the evolutionary relationships among isolates of different formae speciales of Fusarium oxysporum was examined, with a special emphasis on the forma specialis melonis. Bootstrapped maximum likelihood analysis of the elongation factor-1α (EF-1α) sequence was...

Species of the Fusarium solani species complex (FSSC) are responsible for the Fusarium wilt disease of melon (Cucumis melo), a major disease of this crop in Iran. According to a recent taxonomic revision of Fusarium based primarily on multilocus phylogenetic analysis, Neocosmospora, a genus distinct from Fusarium sensu stricto, has been proposed to...

In spring 2018, melon (Cucumis melo L.) plants with wilting of the leaves and dry rot of the crowns were observed in Dashti county, Bushehr province, southern Iran. Nine fungal isolates were recovered from the symptomatic crowns. Based on the morphological characteristics and DNA sequences of the internal transcribed spacer (ITS) region of ribosoma...

During 2017–2018, leaf spots were observed on Japanese privet plants in commercial greenhouses and ornamental nurseries in Tehran, Fars and Bushehr provinces, Iran. Due to the high severity of the symptoms, this study was conducted to identify the causal agents. Based on morphological characteristics and molecular analyses of six loci (ITS, act, te...

Citrus decline has become a devastating problem in citrus-growing regions of southern Iran. The affected trees show progressive yellowing of leaves, thinning of the canopy, dieback and total collapse. Despite a number of attempts, the aetiology of the decline has remained uncertain. In the present study, we evaluated the potential association of va...

Cucumis melo fruits showing symptoms of irregular brown lesions were collected in Mohr region, Fars province, Iran. Based on morphological characteristics and DNA sequence of the internal transcribed spacer (ITS) region, the isolated pathogen was identified as Neoscytalidium hyalinum. Arthroconidia were isolated from fruit rot symptoms inoculated i...

Cultivars of Cucumis melo L. are important economic crops planted in both saline and non-saline soils in Iran. Root rot on C. melo caused by Phytophthora melonis is one of the most devastating soil-borne diseases causing great loss. C. melo crops cultivated in saline soil adjacent to Maharloo Lake (salt lake) in Fars Province have been associated w...

Severe dieback of rose has been recently observed in several rose greenhouses in Fars province of Iran. During 2014 and 2015, stems of rose plants showing yellow to brown discoloration and dieback were collected from rose greenhouses. Coniothyrium fuckelii, Botrytis cinerea and Acremonium were subsequently isolated from the margin between healthy a...

Fusarium wilt of melon caused by Fusarium oxysporum f. sp. melonis is a destructive fungal disease in melon growing regions. Isolates of F. oxysporum obtained from six major melon producing provinces in Iran, from melons and other hosts, were characterized based on pathogenicity to melon, vegetative compatibility groups (VCGs) and nuclear ribosomal...

Safflower seedlings were used to discriminate two morphologically similar species of Phytophthora namely P. melonis and P. drechsleri. All isolates of P. melonis from different sources could not infect safflower seedlings under high inoculum potential whereas all isolates of P. drechsleri from various hosts attacked safflower within a short period....
