Common bacterial blight (CBB) is caused by four genetic lineages belonging to two species of Xanthomonas, namely Xanthomonas citri pv. fuscans (includes fuscans, NF2 and NF3 lineages) and X. phaseoli pv. phaseoli (lineage NF1). A collection of 117 strains of Xanthomonas isolated from common bean plants grown in several producing regions of Brazil, between 2007 and 2016 was established. For species and lineage identification, the following tests were performed: multiplex PCR with a set of four specific primer pairs, pathogenicity tests on susceptible cultivar BRS Artico and phylogenetic analysis based on housekeeping gene sequences. The presence of the two species were confirmed among the 117 strains, being 62 non-fuscans strains (NF1, NF2 and NF3) and 55 fuscans strains of X. citri pv. fuscans. To select a set of representative strains for the virulence assay, a PCR-based analysis of effector diversity was performed with 42 strains belonging to the two species. PCR with primers for xopL, avrBsT, xopE2 and xopE1 genes were positive for all strains, while for the other six effectors there was variation. Six distinct effector profiles were detected, and one strain representing each type was inoculated in 15 common bean cultivars with varying levels of resistance to CBB. The fuscans strains showed uniformity in their effector profiles and were the most virulent. The phylogenetic analyses of our strain collection revealed that all genetic variants of CBB pathogens (NF1, NF2, NF3 and fuscans) are present in Brazil, with significant variability in virulence to common bean cultivars.

Propôs-se nesse estudo, buscar e sistematizar conhecimentos e informações no contexto dos limites da cadeia produtiva do cupuaçu, identificando seus pontos de estrangulamento de maneira que as demandas de pesquisa, assistência técnica e logística fossem percebidas com a intenção de subsidiar as decisões do setor privado e governamental, considerando a produção gerada nos SAF's, onde o cupuaçu é um dos principais componentes, porém sem prejuízo dos sistemas de monocultivo e de quintal. Levantou-se o perfil dos produtores, agroindústria, organizações não-governamentais (ONGs) diretamente envolvidas, extensão rural, pesquisa, varejistas, atacadistas, lanchonetes, consumidores e outras informações consideradas estratégicas nas tomadas de decisões dos agentes econômicos e/ou de apoio ao negócio cupuaçu. |
