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...
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...
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...
Os Begomovirus fazem parte de uma família numerosa fitovírus denominada Geminiviridae. Eles infectam ampla gama hospedeiras, incluindo muitas espécies cultivadas, como tomate (Lycopersicon esculentum), feijão (Phaseolus vulgaris), pimentão (Capsicum annuum), caupi (Vigna unguiculata), mandioca (Manihot esculenta) etc., além plantas invasoras várias espécies. Em alguns casos, podem funcionar reservatórios desses vírus para mediante transmissão pelo inseto-vetor. No presente trabalho, com...
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...
