A survey of begomoviruses infecting leguminous weeds (family Fabaceae) was carried out in four states northeastern Brazil. total 26 full‐length begomovirus components (19 DNA‐A and seven DNA‐B, with three pairs cognate B components) were amplified using rolling‐circle amplification, then cloned sequenced. Sequence analysis indicated the presence six species, them novel. In phylogenetic five viruses clustered other Brazilian begomoviruses, but one ( Euphorbia yellow mosaic virus, EuYMV) from...
Begomoviruses are whitefly-transmitted, ssDNA plant viruses and among the most damaging pathogens causing epidemics in economically important crops worldwide. Wild/non-cultivated plants play a crucial epidemiological role, acting as begomovirus reservoirs ‘mixing vessels' where recombination can occur. Previous work suggests higher degree of genetic variability populations from non-cultivated hosts compared with cultivated hosts. To assess this supposed host effect on populations, (common...
Considerando a relevância da antracnose para as anonáceas qual é uma das principais limitações ao cultivo dessas frutíferas, o controle biológico alternativa promissora no manejo de doenças plantas, oferecendo boa eficiência, baixo custo e impacto ambiental. Diante disso, objetivo deste trabalho foi avaliar potencial antagonista Trichoderma harzianum (Trichodermil SC 1306/KOPPERT) sobre três isolados Colletotrichum theobromicola (12 ALP, 58 ALG 102 ALA). Para testar essa interação, realizado...
O objetivo do trabalho foi avaliar in vitro os efeitos de T. harzianum sobre cinco espécies Colletotrichum. Para o teste pareamento foram inoculadas as Colletotrichum spp. em meio BDA sintético e após 72 horas adicionado antagonista harzianum, na direção oposta aos fitopatógenos. avaliação da ação metabólitos espécie no centro placas Petri, separadamente 48 inoculado contendo sintético. As bases das fitopatógeno unidas vedadas. Foram estimados índice crescimento micelial (IVCM) a porcentagem...
Brazil is the world's largest producer of passion fruit (Passiflora spp.), with Northeast region accounting for 70% national production. In this scenario, fungal diseases such as anthracnose, caused by species Colletotrichum genus, are among main factors reducing yield and affecting quality. From perspective, study aimed to evaluate in vitro effects fungicides difenoconazole, pyraclostrobin, flutriafol, azoxystrobin + difenoconazole (Amistar Top®) on mycelial growth plurivorum, C....
Abstract Several key evolutionary events marked the evolution of geminiviruses, culminating with emergence divided (bipartite) genomes represented by viruses classified in genus Begomovirus . This represents most abundant group multipartite viruses, contributing significantly to observed abundance species virosphere. Although aspects related virus‐host interactions and dynamics have been extensively studied, bipartite nature these has little explored studies. Here, we performed a parallel...
Begomoviruses are whitefly-transmitted, single-stranded DNA viruses that often associated with weed plants. The aim of this study was to further characterize the diversity begomoviruses infecting weeds (mostly Sida spp.) in Brazil. Total extracted from samples collected Viçosa (Minas Gerais state) and some municipalities Alagoas state 2009 2010. Viral genomes were amplified by RCA, cloned sequenced. A total 26 DNA-A clones obtained. Sequence analysis indicated presence 10 begomoviruses. All...
The production of faba bean (Phaseolus lunatus) is limited due to the occurrence Rhizoctonia canker, caused by fungus solani. In order select materials with potential for use in beans breeding programs and/or disease integrated management, 72 genotypes were evaluated and also stability resistance relation different pathogen isolates, inoculum densities soil type. seeds sown infested addition colonized substrate (rice grains). evaluation was done after 15 days, using a note scale discriminate...
A podridão do colo, causada por Sclerotium rolfsii, é uma importante doença feijão-fava (Phaseolus lunatus) no Nordeste brasileiro. O objetivo deste trabalho foi avaliar a reação de genótipos S. visando selecionar materiais com potencial utilização manejo da colo. Na primeira etapa, 50 foram avaliados em relação um isolado rolfsii. Plantas 10 dias idade inoculadas pelo método ferimento colo e deposição escleródio patógeno. incidência avaliada após inoculação. maioria dos (60%) se comportou...
Anthracnose, caused by Colletotrichum spp., is an important disease of atemoya that can infect and cause damage to different plant organs. The symptoms include foliar anthracnose, flower abortion, branch tip bleaching, necrotic lesions on fruits. Knowing the etiology this essential for properly developing management strategies. Therefore, study aimed identify species associated with in Northeast region Brazil, based multi-locus phylogeny morphological analyses, better understand anthracnose...
