Detection and molecular characterization of Grapevine yellow speckle viroid 1 isolates infecting grapevines in Brazil.

Abstract Presently, Hop stunt viroid(HSVd) and Citrus exocortis viroid (CEVd) are the only viroids reported to infect grapevines (Vitis spp.) in Brazil, among the seven viroid species already reported infecting this host in other countries. All grapevine viroid diseases are graft-transmissible and can induce losses especiallywhenassociatedwithviruses.Theaimofthisworkwas to confirm infection by Grapevine yellow speckle viroid 1(GYSVd-1) in grapevine samples exhibiting yellow speckle symptoms in the leaves and in asymptomatic samples sequenced by next generation sequencing (NGS). The occurrence of this viroid in Brazil was further investigated in a second study. Total RNAs and dsRNAs were extracted from five symptomatic plants and 16 asymptomatic samples, respectively. Specific primers were used for RT-PCR and amplified DNA fragments were cloned and sequenced by the Sanger method. Eleven complete nucleotide sequences of GYSVd-1 isolates (366 ?367 nt) were obtained from NGS and from RT-PCR amplicons. Comparisons showed high identities (95.9 ?100 %) among ten isolates and an identity of 87.2 ?90.4 % with a divergent isolate (RM-BR). Phylogenetic analyses placed GYSVd-1 isolates in four clusters (types 1, 2, 3 and 4). All GYSVd-1 infections were confirmed by conventional RT-PCR and RT-qPCR using specific oligonucleo-tides and a labeled probe. This is the first report and molecular characterization of GYSVd-1 infecting grapevines in Brazil, and our survey indicates that this viroid could be widespread in the major grape producing regions of Brazil.

Indicadores de sustentabilidade como sistema avaliativo de agroecossistemas.

Com o objetivo de avaliar de maneira participativa a qualidade do solo, do ambiente e do cultivo e verificar os efeitos gerados peals práticas e tecnologias empregadas nas propriedades agrícolas, os indicadores de sustentabilidade têm se mostrado bastante eficazes tanto nas avaliações quanto na percepção do produtor do que é preciso fazer para melhorar a condição atual.
