Despite the importance of viral strains/variants as agents of emerging diseases, genetic and evolutionary processes affecting their ecology are not fully understood. To get insight into this topic, we assessed the population and spatial dynamic parameters of citrus leprosis virus C (CiLV-C, genus Cilevirus, family Kitaviridae). CiLV-C is the etiological agent of citrus leprosis disease, a non-systemic infection considered the main viral disorder affecting citrus orchards in Brazil. Overall, we obtained 18 complete or near-complete viral genomes, 123 complete nucleotide sequences of the open reading frame (ORF) encoding the putative coat protein, and 204 partial nucleotide sequences of the ORF encoding the movement protein, from 430 infected Citrus spp. samples collected between 1932 and 2020. A thorough examination of the collected dataset suggested that the CiLV-C population consists of the major lineages CRD and SJP, unevenly distributed, plus a third one called ASU identified in this work, which is represented by a single isolate found in an herbarium sample collected in Asuncion, Paraguay, in 1937. Viruses from the three lineages share about 85% nucleotide sequence identity and show signs of inter-clade recombination events. Members of the lineage CRD were identified both in commercial and non-commercial citrus orchards. However, those of the lineages SJP were exclusively detected in samples collected in the citrus belt of São Paulo and Minas Gerais, the leading Brazilian citrus production region, after 2015. The most recent common ancestor of viruses of the three lineages dates back to, at least, ?1500 years ago. Since citrus plants were introduced in the Americas by the Portuguese around the 1520s, the Bayesian phylodynamic analysis suggested that the ancestors of the main CiLV-C lineages likely originated in contact with native vegetation of South America. The intensive expansion of CRD and SJP lineages in Brazil started probably linked to the beginning of the local citrus industry. The high prevalence of CiLV-C in the citrus belt of Brazil likely ensues from the intensive connectivity between orchards, which represents a potential risk toward pathogen saturation across the region.

O Núcleo de Agroecologia do Semiárido foi instituído na Embrapa Semiárido em 2014. Seu objetivo principal é mobilizar equipes interdisciplinares e articular parcerias com universidades, instituições de ATER e agricultores (as) familiares para promover ações de intercâmbio e construção do conhecimento agroecológico com enfoque territorial. Suas ações têm estreita relação com a formação de jovens agricultores da Escola Família Agrícola de Sobradinho/BA, organizações de ATER e instituições públicas de ensino, pesquisa e extensão. Tais ações tem como foco a agrobiodiversidade, a sociobiodiversidade, os sistemas agroflorestais e o redesenho de agroecossistemas, inter-relacionando e aplicando os fundamentos da Agroecologia para a Convivência com o Semiárido. Neste sentido, o objetivo do presente relato é apresentar as ações desenvolvidas pelo referido núcleo durante o período de 2014 a 2017 nos Territórios do Sertão do São Francisco baiano e pernambucano. |
