“…In case of stress combinations involving heat and pathogen stress, high temperatures not only affect plants but also pathogens. Temperature is, in fact, one of the most important factors affecting the occurrence of bacterial diseases such as those caused by Ralstonia solanacearum (causal agent of wilt in tomato), Acidovorax avenae (causal agent of seedling blight and bacterial fruit blotch of cucurbits) and Burkholderia glumae (causal agent of bacterial panicle blight in rice) ( Kudela, 2009 ). An increase in temperature modifies the growth rate and reproduction of pathogens ( Ladanyi and Horvath, 2010 ).…”

Global warming leads to the concurrence of a number of abiotic and biotic stresses, thus affecting agricultural productivity. Occurrence of abiotic stresses can alter plant–pest interactions by enhancing host plant susceptibility to pathogenic organisms, insects, and by reducing competitive ability with weeds. On the contrary, some pests may alter plant response to abiotic stress factors. Therefore, systematic studies are pivotal to understand the effect of concurrent abiotic and biotic stress conditions on crop productivity. However, to date, a collective database on the occurrence of various stress combinations in agriculturally prominent areas is not available. This review attempts to assemble published information on this topic, with a particular focus on the impact of combined drought and pathogen stresses on crop productivity. In doing so, this review highlights some agriculturally important morpho-physiological traits that can be utilized to identify genotypes with combined stress tolerance. In addition, this review outlines potential role of recent genomic tools in deciphering combined stress tolerance in plants. This review will, therefore, be helpful for agronomists and field pathologists in assessing the impact of the interactions between drought and plant-pathogens on crop performance. Further, the review will be helpful for physiologists and molecular biologists to design agronomically relevant strategies for the development of broad spectrum stress tolerant crops.

“…Some ecoregions will be more affected than others by climate changes (Engler et al 2011;Heyder et al 2011;Teixeira et al 2012), with the most biodiverse ecoregions particularly at risk (Beaumont et al 2011). In Europe, Southern regions are predicted to be more sensitive to climate change than Northern ones, due to increases in summer drought (Kůdela 2009). In North America, the temperature increase is expected to be greater than the global average, particularly in boreal and mountainous regions (Bentz et al 2010).…”

Impacts of climate change on plant diseases—opinions and trends

There has been a remarkable scientific output on the topic of how climate change is likely to affect plant diseases. This overview addresses the need for review of this burgeoning literature by summarizing opinions of previous reviews and trends in recent studies on the impacts of climate change on plant health. Sudden Oak Death is used as an introductory case study: Californian forests could become even more susceptible to this emerging plant disease, if spring precipitations will be accompanied by warmer temperatures, although climate shifts may also affect the current synchronicity between host cambium activity and pathogen colonization rate. A summary of observed and predicted climate changes, as well as of direct effects of climate change on pathosystems, is provided. Prediction and management of climate change effects on plant health are complicated by indirect effects and the interactions with global change drivers. Uncertainty in models of plant disease development under climate change calls for a diversity of management strategies, from more participatory approaches to interdisciplinary science. Involvement of stakeholders and scientists from outside plant pathology shows the importance of trade-offs, for example in the land-sharing vs. sparing debate. Further research is needed on climate change and plant health in mountain, boreal, Mediterranean and tropical regions, with multiple climate change factors and scenarios (including our responses to it, e.g. the assisted migration of plants), in relation to endophytes, viruses and mycorrhiza, using long-term and large-scale datasets and considering various plant disease control methods.Keywords Adaptive ecosystem management .

“…in western Algeria. Plant pathogenic prokaryotes, like other plant pathogens, are influenced by a variety of factors, including local climate, host plant distribution, pathogen dispersal ability, occurrence of animal vectors, pathogen adaptability to local conditions, pathogen capacity to infect new host plants, and local cultivar resistance (Kudela, 2009). E. carotovora was becoming a concern because of the environmental conditions in the eastern areas of Algeria.…”

Rapid screening of phytopathogenic Erwinia sp. of two potato varieties (Spunta and Desiree) from Algerian agricultural fileds. Isolation, phenotypic identification and in vitro phytopathogenicity screening of Erwinia sp. from agricultural field of two potato varieties (Spunta and Desiree) in Algeria. The current study aims to isolate, identify and screen phytopathogenic isolates of Erwinia sp. causing potato diseases. The techniques presented in this study for isolation and characterization of phytopathogenic Erwinia sp. are conventional methods that are used in this field of research. Seven phytopathogenic bacteria were recovered from potato tubers of two varieties (Spunta and Desiree). The phenotypic identification allowed characterizing typical colonies of Erwinia sp. on two semi-selective media: King’s B and TCC media. Erwinia sp. formed characteristic colonies on King’s B medium that were round, convex and representing creamy color. While, Erwinia sp. also developed specific colonies on TCC medium which were pale purple, circular, convex, even bulging; smooth and mucous. In vitro phytopathogenicity test on potato slices lead to screen the phytopathogenic isolate E5 characterized by highest rotten tissue zone of (2.33 ± 0.29 cm) and (2.33 ± 0.58 cm) toward Spunta and Desiree varieties, respectively. Followed, by isolate E4 characterized by rotten tissue zone of (1.83 ± 0.58 cm) and (2.17 ± 0.29 cm) toward Spunta and Desiree varieties, respectively; compared to their corresponding uninfected controls. The RTZ (Rotten tissue zone) evidently is proportional to the specific pathogenicity of Erwinia sp. isolates and the characteristic sensitivity of various varieties (Spunta and Desiree). Thus, make determining RTZ a rapid screening technique for the selection of the highest phytopathogenic isolates. This investigation provides valuable information for rapid screening (infected potato tuber) and characterization (isolation using semi-selective media) of pathogenic Erwinia sp. engendering potato disease compared to existing methods like infection of leaves or plants; and phytopathogenic Erwinia sp. identification through PCR amplification or in situ hybridation.
