Detecção e análise da variabilidade de seqüências do Banana streak virus (BSV) em bananeiras no Brasil

Abstract: PCR assay using degenerate primers, designed to Badnavirus genus, was used to detect and analyse the variability of BSV strains sequences from banana. The virus was detected in diploid (AA), triploids (AAA; AAB) and tetraploids (AAAB) banana cultivars. Four BSV sequences patterns (BSVBR-1, BSVBR-2, BSVBR-3 and BSVBR-4 strains) were found, and distinguished by eletrophoresis. The strain BSVBR-1 was found in the states of Acre, Amazonas, RESUMOA técnica de PCR utilizando-se "primers" degenerados para o gênero Ba… Show more

“…This high genetic variability previously reported in the complex of viral species responsible for the disease Banana streak viruses (BSVs) in banana plants (Musa spp.) (HARPER & HULL, 1998;HARPER et al, 2005;FIGUEIREDO et al, 2006), as well as for the virus Dioscorea bacilliform AL virus (DBALV) in the yam crop (Dioscorea spp.) (LIMA et al, 2013).…”

“…Recentes relatos sugerem que todas as bananeiras híbridas estariam potencialmente infectadas com o BSV, pois um complexo BSV integrante denominado EPRV ("endogenous pararetrovirus sequence") presente no genoma B da bananeira seria capaz de originar infecção epissomal, quando a planta é submetida à cultura de tecidos (11,12,13,19). Contudo, recentes resultados obtidos pelo nosso grupo de pesquisa demostraram a existência de bananeiras híbridas livres de BSV, sugerindo que há possibilidade de que matrizes livres de BSV ainda sejam encontradas (10).…”

“…In Brazil, the Badnavirus species associated withbanana streakthat have been described so far areBanana streak Uganda virus (BSUgBV) [14,15] and Banana streak OL virus(BSOLV). Other genetic variants, called BRSV-BR1, BRSV-BR2, BRSV-BR3, and BRSV-BR4, have also been described by Figueiredo et al [16], but have not been characterized genetically.This study describes a species of Badnavirus not previously reported in Brazil.…”
