“…Isolates infecting potato are now distributed among the six described species of Dickeya (Samson et al 2005) and it remains unclear whether these strains produce the same symptoms during disease development, or whether only some are responsible for blackleglike symptoms. The discovery of distinct species of Pectobacterium and Dickeya associated with certain hosts supports the idea that identifiable groups of pectinolytic enterobacteria are found in specific ecological niches and may be responsible for variable disease symptoms on potato depending on the prevailing environmental conditions (De Boer 2003, Czajkowski et al 2011.…”

“…Blackleg is an economically important disease and is characterised by the blackening of the stem base of potato plants, which originates from the rotting mother tuber (Pèrombelon 2002, Czajkowski et al 2011. Blackleg is unpredictable in the field due to the ability of the pathogen to remain latent in the seed tuber (Laurila et al 2008).…”

Agriculture in the twenty-first century faces the challenge of meeting food demands while satisfying sustainability goals. The challenge is further complicated by climate change which affects the distribution of crop pests (intended as insects, plants, and pathogenic agents injurious to crops) and the severity of their outbreaks. Increasing concerns over health and the environment as well as new legislation on pesticide use, particularly in the European Union, urge us to find sustainable alternatives to pesticide-based pest management. Here, we review the effect of climate change on crop protection and propose strategies to reduce the impact of future invasive as well as rapidly evolving resident populations. The major points are the following: (1) the main consequence of climate change and globalization is a heightened level of unpredictability of spatial and temporal interactions between weather, cropping systems, and pests; (2) the unpredictable adaptation of pests to a changing environment primarily creates uncertainty and projected changes do not automatically translate into doom and gloom scenarios; (3) faced with uncertainty, policy, research, and extension should prepare for worst-case scenarios following a "no regrets" approach that promotes resilience vis-à-vis pests which, at the biophysical level, entails uncovering what currently makes cropping systems resilient, while at the organizational level, the capacity to adapt needs to be recognized and strengthened; (4) more collective approaches involving extension and other stakeholders will help meet the challenge of developing more robust cropping systems; (5) farmers can take advantage of Web 2.0 and other new technologies to make the exchange of updated information quicker and easier; (6) cooperationThe views expressed by Stephen R. H. Langrell are purely his own and may not in any circumstances be regarded as stating an official position of the European Commission.

“…There is currently no effective method available to control the disease caused by P. atrosepticum. No chemical agents are efficient against these pathogens and cultural practices and storage conditions are unable to prevent the spread of the disease (Priou and Jouan, 1996;Czajkowski et al, 2011;Yaganza et al, 2014).…”

Background and aims Potato (Solanum tuberosum) is an important food crop and is grown worldwide. It is, however, significantly sensitive to a number of soil-borne pathogens that affect roots and tubers, causing considerable economic losses. So far, most research on potato has been dedicated to tubers and hence little attention has been paid to root structure and function.Methods In the present study we characterized root border cells using histochemical staining, immunofluorescence labelling of cell wall polysaccharides epitopes and observation using laser confocal microscopy. The monosaccharide composition of the secreted exudates was determined by gas chromatography of trimethylsilyl methylglycoside derivatives. The effects of root exudates and secreted arabinogalactan proteins on bacterial growth were investigated using in vitro bioassays.Key Results Root exudate from S. tuberosum was highly enriched in galactose-containing molecules including arabinogalactan proteins as major components. Treatment of the root with an elicitor derived from Pectobacterium atrosepticum, a soil-borne pathogen of potato, altered the composition of the exudates and arabinogalactan proteins. We found that the growth of the bacterium in vitro was differentially affected by exudates from elicited and nonelicited roots (i.e. inhibition versus stimulation).Conclusions Taken together, these findings indicate that galactose-containing polymers of potato root exudates play a central role in root-microbe interactions.
