“…Pectobacterium aroidearum was classified as a novel species in 2013 (Nabhan et al, 2013). In previous studies, bacterial soft rot disease was caused by P. aroidearum in calla (Zantedeschia aethiopica; Nabhan et al, 2013), potato (Solanum tuberosum;Moretti et al, 2016), Chinese cabbage (Brassica rapa; Xie et al, 2017), zucchini (Cucurbita pepo; Moraes et al, 2017), konjac (Amorphophallus konjac; Sun et al, 2019), pepper (Capsicum annuum; Moraes et al, 2020), and carrot (Daucus carota; Tang et al, 2021). In our previous research, P. aroidearum as a pathogen on S. podophyllum was found in China (Xu et al, 2020).…”

Soft rot pectobacteria are devastating plant pathogens with a global distribution and a broad host range. Pectobacterium aroidearum L6, previously isolated from leaves of Syngonium podophyllum, is a pectolytic bacterial pathogen that causes typical soft rot on S. podophyllum. There is a shortage for genome data of P. aroidearum, which seriously hinders research on classification and pathogenesis of Pectobacterium. We present here the complete genome sequence of P. aroidearum L6. The L6 strain carries a single 4,995,896-bp chromosome with 53.10% G + C content and harbors 4,306 predicted protein-coding genes. We estimated in silico DNA–DNA hybridization and average nucleotide identity values in combination with the whole-genome-based phylogeny from 19 Pectobacterium strains including P. aroidearum L6. The results showed that L6 and PC1 formed a population distinct from other populations of the Pectobacterium genus. Phylogenetic analysis based on 16S rRNA and genome sequences showed a close evolutionary relationship among Pectobacterium species. Overall, evolutionary analysis showed that L6 was in the same branch with PC1. In comparison with 18 Pectobacterium spp. reference pathogens, strain L6 had 2,712 gene families, among which 1,632 gene families were identified as orthologous to those strains, as well as 1 putative unique gene family. We discovered 478 genes, 10.4% of the total of predicted genes, that were potentially related to pathogenesis using the Virulence Factors of Pathogenic Bacteria database. A total of 25 genes were related to toxins, 35 encoded plant cell-wall degrading enzymes, and 122 were involved in secretion systems. This study provides a foundation for a better understanding of the genomic structure of P. aroidearum and particularly offers information for the discovery of potential pathogenic factors and the development of more effective strategies against this pathogen.

“…Así, se ha reportado P. carotovorum afectando tomate y espatifilo en Argentina (Alippi y López, 2009). P. aroiderum en lechuga, col china y pimiento en Brasil (Barroso et al, 2019;Moraes et al, 2020). En tanto, las especies P. atrosepticum, P. brasiliense, P. carotovorum, P. odoriferum, P. parmentieri, P. peruviense, P. polaris y P. punjabense son asociadas a papa (Nabhan et al, 2013), siendo la más relevante P. brasiliense (Duarte et al, 2004)…”

Una enfermedad en plantas es el resultado de la interacción génica compatible entre un hospedero susceptible, un patógeno virulento y condiciones medioambientales favorables. Así, diversos factores direccionadores, antropogénicos y ambientales, han favorecido la emergencia y reemergencia de enfermedades que han conllevado a pérdidas importantes en los cultivos. América Latina no es la excepción de la presencia de estos fenómenos evidenciado en primeros reportes para diferentes países, expansión geográfica y en el rango de hospederos de patógenos, aparición de nuevas razas, cepas, variantes e incluso especies de virus, viroides, bacterias, hongos y oomycetos los cuales se han abordado en esta revisión, incluyendo las bacterias de los géneros Candidatus Liberibacter y Candidatus phytoplasma.

“…Geralmente, as cultivares de pimentão disponíveis no mercado são muito suscetíveis ao ataque de doenças de etiologia variada, o que proporciona a baixa produtividade do pimentão quando não são controladas de forma eficaz (JARA, 2015). Segundo Moraes et al (2020) uma das doenças acometidas no pimentão é a podridão mole, causada por Pectobacterium aroidearum, sendo registrada incidência de 10 a 18% de frutos de pimenta ainda colados em plantas com sintomas de podridão mole. Ainda, é considerada uma das dez bactérias fitopatogênicas de maior importância científica e econômica do mundo (MANSFIELD et al, 2012).…”
