Huanglongbing (HLB) is a difficult-to-control and highly destructive citrus disease that, in Brazil, associated mainly with the bacterium 'Candidatus Liberibacter asiaticus' transmitted by psyllid Diaphorina citri. The aim of this study was to improve our understanding 'Ca. L. infection process exposing excised, fully expanded, immature leaves 50-ml Falcon tubes one, four, or eight adults from asiaticus'-exposed colony for 1-, 3-, 7-, 15-day periods access inoculation (IAP). were incubated...
ABSTRACT: Seventy-five pectinolytic strains collected from vegetables grown in the counties of Santarém, Belterra, and Mojuí dos Campos, located western region Pará State, Brazil, were studied according to their pathological genetic variability. The grouped 5 clusters pathogenicity potato, pepper, carrot, onion, 38 selected for analysis using rep-PCR. These divided into 35 groups rep-PCR at 70% similarity. results indicated high variability causing soft rot which will be used etiological...

Abstract Burkholderia cepacia was originally described as the causal agent of onion sour skin. However, this bacterium is now recognized a complex 22 closely related species, commonly referred to B . (BCC). Only few taxonomic studies have been undertaken with aim understanding diversity species associated In study, we used polyphasic analysis including rep‐PCR assay, biochemical and pathological profiles, multilocus sequence (MLSA) characterize BCC skin in semi‐arid region north‐east Brazil....
Citrus canker caused by Xanthomonas citri subsp. is one of the most important citrus diseases in world (Gottwald et al. 2002), mainly for citrus-producing countries with humid sub-tropical regions such as United States, Argentina, and Brazil, where losses may be significant (Behlau 2020). In state Rio Grande do Norte (RN), production expanding shows social economic importance small farmers, which produced approximately 297 tons lime this 2019 (IBGE 2021). December 2019, we observed symptoms...
