Fungi belonging to the genus Cladosporium are cosmopolitan occurring in various substrate or hosts. spp. responsible for economic losses numerous agricultural crops, causing leaf spots, scab, postharvest rots and other disease symptoms. The etiology of many diseases associated with these symptoms is still uncertain. aim this research was determine identity isolates passionfruit scab some on different crops Brazil, based phylogenetic morphological analyses. analyses indicated that all samples...
The authors describe ten new taxa for science using mostly both morphological and molecular data. In Ascomycota, descriptions are provided Bambusistroma didymosporum gen. et spec. nov. (Pleosporales), Neodeightonia licuriensis sp. (Botryosphaeriales) Camposporium himalayanum (Fungi imperfecti). Zygomycota, Gongronella guangdongensis (Mucorales) is described. Finally, in Basidiomycota Boidinia parva Russula katarinae (Russsulales), Gloiocephala parvinelumbonifolia (Agaricales), Hypochnicium...
Coconut palm (Cocos nucifera L.) is one of the most important perennial tropical crops. Stem-end rot major postharvest disease coconut in Brazil. The fungus Lasiodiplodia theobromae only species that has been reported to be associated with this disease. However, a comprehensive study elucidating true identity pathogen molecular tools never conducted. In recent years, new have proposed after studies were performed, indicating existence complex. aims research etiology stem-end immature based...
Here, Quambalaria fabacearum and Neopestalotiopsis brasiliensis are introduced as new species from Brazil, isolated endophyte Mimosa tenuiflora causing post-harvest rot disease on fruits of Psidium guajava, respectively. Diaporthe inconspicua is emended to include a more detailed morphological description. egyptiaca reported the Americas while Umbelopsis isabellina endophyte.
Three field experiments were carried out to assess the level of resistance several cultivars early blight (EB) and examine association between host either foliage maturity or tuber skin types. A total 26 used in Exps. 1 2, 24 Exp. 3. Plants inoculated with isolates Alternaria grandis at 31 days after planting. EB severity was quantified each plot every seven days. The approach determine levels potato based on multivariate analysis techniques. tested responded as resistant, moderately...
The Atlantic Forest has the greatest diversity of plants per hectare, and it is considered main center bamboo biodiversity in world. Studies on bambusicolous fungi are scarce concentrated temperate regions. Cladosporium one largest genera dematiaceous hyphomycetes fungus their adaptation to different environments allows them have a broad lifestyle. Currently, this genus been taxonomically phylogenetically elucidating with help extensive polyphasic analyzes. This study aimed characterize 17...
Fungi belonging to the genus Cladosporium are cosmopolitan and occur in various substrates hosts. Nevertheless, this is first time that we have described colonizing leaf litter submerged water. We surveyed spp. associated with litter, from three localities Atlantic Forest biome State of Minas Gerais, Brazil. A multilocus DNA sequence typing approach employing ITS, Actin, Translation elongation factor 1-α region/genes morphological cultural analyses were used identify these species. The...
Abstract African oil palm ( Elaeis guineensis Jacq.) is considered the most productive oleaginous crop due to its high production per hectare. In April 2015, E. leaves showing elliptical necrotic spots with yellowish halo were observed in a commercial plantation Moju, Pará state, Brazil. A synematous fungus was consistently associated spots. The aim of this study identify Based on morphology and DNA sequence data internal transcribed spacer rDNA, identified as Helminthosporiella stilbacea ....
Abstract In Brazil, Paspalum species are commonly used in sports lawns, landscape projects, and as forage for livestock. guenoarum plants showing symptoms of take‐all disease were observed the state Rio Grande do Sul, Brazil. The fungus Gaeumannomyces graminis is only reported associated with this on . recent years, new have been proposed based molecular studies, which demonstrated existence a complex. Take‐all affects rice wheat, but aetiology P still unknown; work aimed to elucidate Brazil...
Abstract In Brazil, sour rot is an important postharvest disease on fruits and vegetables. Geotrichum candidum (synonym Galactomyces candidus ) has been reported as the main species causing this disease. However, identity of causal agent still uncertain. This research aimed to determine 165 fungal isolates associated with obtained from vegetables in evaluate effect different temperatures incidence artificially inoculated tomato fruits. Based phylogenetic analyses DNA sequences D1/D2 domain...
Abstract Cycas revoluta (Cycadaceae) is commonly cultivated as an ornamental tree in several countries. In April 2015, C. leaves showing brownish spots with a yellow halo that progressed to leaflet necrosis were observed Belém, Pará state, Brazil. This study aimed determine the aetiology of this disease on sago palm Based DNA sequence‐based phylogeny, morphology, and colony characterization, fungus was identified Pseudopestalotiopsis elaeidis . To best our knowledge, first report P....
Coffea canephora is largely produced in Espírito Santo state, Brazil. It known that fungi of the genus Lasiodiplodia cause dieback on Coffea. In July 2019, samples C. with symptoms were collected Santa Tereza, This study aimed to determine etiology this disease, based multilocus phylogeny, morphology, and colony characterization. The causal agent was identified as iranensis. To best our knowledge, first report iranensis causing worldwide.
