“…Pcc is widely distributed in the world and has a broad host range (De Boer et al 1987;Smith and Bartz 1990;Kang et al 2003). Studies under high temperature conditions in North America Harrison 1977, 1980) and Australia (Peltzer and Sivasithamparam 1985) showed that Pcc isolates, inoculated into tubers or stems, could cause typical blackleg symptoms in the field. Also Powelson and Apple (1984) suggested that soil-borne strains of Pcc can cause disease symptoms under irrigated field conditions in the Pacific Northwest of America.…”

Pectobacterium carotovorum subsp. carotovorum can cause potato blackleg in temperate climates

et al. 2008

It is well established that the pectinolytic bacteria Pectobacterium atrosepticum (Pca) and Dickeya spp. are causal organisms of blackleg in potato. In temperate climates, the role of Pectobacterium carotovorum subsp. carotovorum (Pcc) in potato blackleg, however, is unclear. In different western and central European countries plants are frequently found with blackleg from which only Pcc can be isolated, but not Pca or Dickeya spp. Nevertheless, tubers vacuum-infiltrated with Pcc strains have so far never yielded blackleg-diseased plants in field experiments in temperate climates. In this study, it is shown that potato tubers, vacuum-infiltrated with a subgroup of Pcc strains isolated in Europe, and planted in two different soil types, can result in up to 50% blackleg diseased plants. All three pathogens can cause tuber rot during storage, whereas infections of seed potatoes with Pca and Dickeya spp. can also result in the occurrence of various field symptoms, including reduced emergence, chlorosis, wilting, tuber and stem rot, blackleg, haulm desiccation and plant death (Pérombelon and Kelman 1980;Pérombelon 1992;Fraaije et al. 1996;Helias et al. 2000). These symptoms can be caused by Pca as well as by Dickeya spp., making identification of the causal organism by visual observation in the field unreliable. Regulatory field inspections in seed potatoes in many countries are therefore based on recognition of this 'blackleg complex' without discriminating between the various blackleg-causing organisms.

“…Pectobacterium carotovorum subsp. carotovorum has a broad host range, including but not limited to carrots, potatoes, cabbage, lettuce and onions across a number of climatic zones including Europe (Peltzer and Sivasithamparam 1985;Waleron et al 2002;Pérombelon 2002;Gardan et al 2003;Toth et al 2003;Crowhurst and Wright 1998;de Haan et al 2008;van der Merwe et al 2010;Cariddi and Sanzani 2013;Onkendi and Moleleki 2014;Moretti et al 2016;Dees et al 2017a;Naas et al 2018;Oztruk et al 2018).

Pectobacterium and Dickeya species detected in vegetables in Northern Ireland

et al. 2019

Destructive soft rot Pectobacteriaceae affect a number of vegetable crops and cause high economic loses in the field and storage. The diversity of Pectobacterium and Dickeya causing soft rot of vegetables in Northern Ireland is unknown. This study provides details of Pectobacterium and Dickeya spp. detected in vegetables from several locations in Northern I r e l a n d i n t h e y e a r s 2 0 1 5-2 0 1 7. S o f t r o t Pectobacteriaceae were identified based on DNA sequences. Thirty three strains were selected for further phylogenetic analysis based on the recA gene region. Results from the testing of over 3456 potato samples for plant health statutory purposes in the years 2005-2017 demonstrated that Dickeya spp. is not the major pathogen causing soft rot or blackleg in Northern Ireland. The most predominant species causing soft rot of vegetables in Northern Ireland were Pectobacterium atrosepticum and Pectobacterium carotovorum subsp. carotovorum. Pectobacterium atrosepticum was also detected on hosts other than potato. Testing of bacteria isolated from carrots led to the detection of P. carotovorum and Dickeya sp. This is the first study to provide knowledge about Pectobacterium and Dickeya spp. diversity causing soft rot of vegetables in Northern Ireland confirmed by real-time PCR and DNA sequences. This is also the first report of the detection of D. aquatica from a source other than water.

“…Potato tuber losses during storage and in transit due to bacterial soft rot caused by Pa and Pcc are of worldwide occurrence and importance (McGuire and Kelman, 1983;Bain and Pérombelon, 1988;Snijder and van Tuyl, 2003) and the species of Pectobacterium that cause soft rots vary with climatic conditions and geographical location (Peltzer and Sivasithamparam, 1985). The Pectobacterium carotovora subspecies carotovora occurs both in temperate and warm climates while P. atroseptica is restricted to temperate climates (Perombelon, 2000).…”

Contamination of potato with soft rotting enterobacteria belonging to the Pectobacterium and Dickeya genera is one of the biggest problems in potato production. Calcium plays an important role in minimising the severity and incidence of potato tuber soft rot in storage. This review gives a detailed assessment of the epidemiology of the pathogens and how calcium affects potato tuber soft rot in storage.
