“…On the basis of available studies reporting the presence of Pbr in the host plants, more than 50% of them have been associated with potato (this study, Table 1 ). In fact, Pbr has been reported in potato in Brazil since 2004 [ 11 ], followed by its detection in North America [ 66 , 67 , 68 ], Europe [ 12 , 13 , 14 , 69 , 70 ], Africa [ 7 , 9 , 71 , 72 ], Asia [ 62 , 73 , 74 , 75 , 76 ], and New Zealand [ 77 ]. Generally, Pbr causes blackleg and soft rot in potato leaves, stems, and tubers [ 8 , 10 , 66 , 68 , 74 ].…”

Pectobacterium brasiliense: Genomics, Host Range and Disease Management

Pectobacterium brasiliense (Pbr) is considered as one of the most virulent species among the Pectobacteriaceae. This species has a broad host range within horticulture crops and is well distributed elsewhere. It has been found to be pathogenic not only in the field causing blackleg and soft rot of potato, but it is also transmitted via storage causing soft rot of other vegetables. Genomic analysis and other cost-effective molecular detection methods such as a quantitative polymerase chain reaction (qPCR) are essential to investigate the ecology and pathogenesis of the Pbr. The lack of fast, field deployable point-of-care testing (POCT) methods, specific control strategies and current limited genomic knowledge make management of this species difficult. Thus far, no comprehensive review exists about Pbr, however there is an intense need to research the biology, detection, pathogenicity and management of Pbr, not only because of its fast distribution across Europe and other countries but also due to its increased survival to various climatic conditions. This review outlines the information available in peer-reviewed literature regarding host range, detection methods, genomics, geographical distribution, nomenclature and taxonomical evolution along with some of the possible management and control strategies. In summary, the conclusions and a further directions highlight the management of this species.

“…Potato stem rot caused by P. versatile (Han et al, 2022) and P. parvum (Wang et al, 2022a) was reported in the Fengning region in the summer of 2020; therefore, seven Pectobacterium species have been identified in potato plants in Hebei Province to date. MLSA demonstrated that a greater diversity of Pectobacterium infects potatoes at the province scale than previously reported: P. carotovorum, P. atrosepticum, P. brasiliense, P. parmentieri, P. polaris and P. punjabense in Guangdong, Inner Mongolia and Sichuan (Zhang et al, 2012;She et al, 2013;Zhao et al, 2018;Jiang et al, 2019;Cao et al, 2021;Handique et al, 2022a;Handique et al, 2022b). However, the P. carotovorum complex has been revised several times, and it is possible that some earlier isolated P. carotovorum strains might have been misclassified.…”

“…Production of Xisen 6 and Huangxin 226 has expanded rapidly in recent years in China due to the consumer preference. Unfortunately, these cultivars are highly susceptible to Pectobacterium species, which have been reported in Guangdong (Jiang et al, 2019), Hebei (Han et al, 2022;Wang et al, 2022a), and Inner Mongolia (Cao et al, 2021).…”

“…P. atrosepticum and P. carotovorum were once regarded as the most frequently isolated pathogens that are associated with potato soft rot diseases in China (Zhang et al, 2012;She et al, 2013). In recent years, other Pectobacterium species, including P. brasiliense (Zhao et al, 2018;Jiang et al, 2019), P. parmentieri (Cao et al, 2021), P. versatile (Han et al, 2022), P. polaris (Handique et al, 2022a) and P. punjabense (Handique et al, 2022b), have also been reported in the primary potato growing areas in China. Two citrate negative isolates of P. polaris were reported to cause aerial stem rot in Hebei Province, and subsequent genome-based analysis confirmed that they belonged to the newly established species, P. parvum (Wang et al, 2022a;Wang et al, 2022b).…”

Blackleg and aerial stem rot of potato (Solanum tuberosum L.), caused by soft rot enterobacteria of the genera Pectobacterium and Dickeya, has recently increased years in Hebei Province, China. Field surveys were performed during the 2021 potato growing season in Hebei to identify and characterize bacterial pathogens. Sixteen potato plants showing blackleg or aerial stem rot were collected from three potato-producing areas, and ten representative pectinolytic bacteria were isolated from symptomatic plants. 16S rDNA sequencing and multilocus sequence analysis were performed to determine the taxonomic position of the bacterial isolates. The isolates belonged to the genus Pectobacterium, including Pectobacterium atrosepticum, Pectobacterium carotovorum, Pectobacterium brasiliense, and Pectobacterium parmentieri. The exceptions were isolates BY21311 and BY21312, which belonged to a new species of Pectobacterium polonicum previously found in groundwater. The taxonomy of isolate BY21311 was confirmed using whole genome-based analysis. P. polonicum has only been identified in potato plants on one farm in Baoding region in China. Isolates BY21311 and BY21312 displayed similar physiological and biochemical traits to the type strain DPMP315T. Artificial inoculation assays revealed that isolate BY21311 fulfilled Koch’s postulates for potato blackleg. These findings represent the first time P. polonicum, a water-associated Pectobacterium species may be the cause of blackleg in the field. Interestingly, P. polonicum BY21311 has reduced ability to macerate potato tubers when compared to P. atrosepticum, P. brasiliense, P. versatile, and P. parvum, which is more virulent in tubers than the type strain DPMP315T. The host range of isolate BY21311 was determined by injection method, which can impregnate five plants. Although the genome of isolate BY21311 harbors gene clusters encoding a type III secretion system, it did not elicit a hypersensitive response (HR) in Nicotiana benthamiana or N. tabacum leaves. T3SS effector AvrE and T4SS effector PilN were obtained by predicting isolate BY21311 genome. P. polonicum appears to show significant variations in gene content between two genomes, and gene content varies between isolates BY21311 and DPMP315T, with strain specific-genes involved in many aspects, including lipopolysaccharide biosynthesis, substrate translocation, T4SS and T6SS among others, suggesting that isolates BY21311 and DPMP315T might represent distinct clades within the species.
