“…In this regard, a variety of physical and biological elicitors are capable of inducing resistance responses, but the nature of responses to different elicitors is largely unknown (Wilson & Wisniewski, ; Anwer, ). The use of plant extracts as inducers of resistance is a developing and very promising field of research in plant protection (Song et al ., ; Benouaret et al ., ).…”

The defence responses of grapefruit and lemon to treatment with pomegranate extract (PGE) were investigated. PGE, an alcoholic extract from pomegranate peel, was recently proposed as a means of effective alternative control against postharvest rots. In in vivo experiments, a significant reduction of rots caused by Penicillium digitatum and P. italicum was achieved on artificially inoculated fruits without direct contact between PGE and pathogens. On lemons both pathogens were completely inhibited by PGE at 12 g dry matter L À1 applied 12 and 24 h before the pathogen but a significant reduction of rots was also achieved by inoculating the pathogen immediately after PGE (0 h), indicating a very quick activation of defence responses. Lower, but significant, reductions were also obtained on grapefruits. An increase in reactive oxygen species (ROS) activity, reaching its peak after 24 h, was observed, in agreement with in vivo efficacy trials. Similarly, the expression of five genes involved in activation of defence responses in plants (CHI, CHS, MAPK, MAPKK and PAL) increased following PGE application. Based on the results of the present study, the high efficacy demonstrated for PGE in previous studies can be partially attributed to the induction of resistance in host tissues.

“…tomato DC3000 were grown on solid LB and King's B medium, respectively, containing 100 μg ml −1 rifampicin at 30 C for 2 days. Subsequently, bacteria were scraped off the plates and re-suspended in 10 mM MgCl 2 (Song et al, 2013). To inoculate plants in the hydroponic system, five leaves from each of four 4 weekold plants were treated with 2 μl drops containing P. carotovorum subsp.…”

Plant growth‐promoting archaea trigger induced systemic resistance in Arabidopsis thaliana against Pectobacterium carotovorum and Pseudomonas syringae

Summary Archaea have inhabited the earth for a long period of time and are ubiquitously distributed in diverse environments. However, few studies have focused on the interactions of archaea with other organisms, including eukaryotes such as plants, since it is difficult to cultivate sufficient numbers of archaeal cells for analysis. In this study, we investigated the interaction between soil archaea and Arabidopsis thaliana. We demonstrate for the first time that soil archaea promote plant growth and trigger induced systemic resistance (ISR) against the necrotrophic bacterium Pectobacterium carotovorum subsp. carotovorum SCC1 and biotrophic bacterium Pseudomonas syringae pv. tomato DC3000. Ammonia‐oxidizing archaeon Nitrosocosmicus oleophilus MY3 cells clearly colonized the root surface of Arabidopsis plants, and increased resistance against both pathogenic species via the salicylic acid‐independent signalling pathway. This mechanism of bacterial resistance resembles that underlying soil bacteria‐ and fungi‐mediated ISR signalling. Additionally, volatile emissions from N. oleophilus MY3 were identified as major archaeal determinants that elicit ISR. Our results lay a foundation for archaea–plant interactions as a new field of research.

“…These biocontrol agents could be also evaluated in combination with the quorum-quenching Rhodococcus erythropolis (55)(56)(57) or with other proposed strategies using plant defense stimulation, predators, or competitors (28)(29)(30)(31)(32)(33)(34)(39)(40)(41)(42)(43)(44)(45)(46)(47)(48). In regard to the practicality of using such findings, this strategy used only 3 treatments by the biocontrol agents.…”

“…Different compounds (natural or synthetic), such as salicylic acid, 2-aminobenzoic acid, alpha-elicitins, and complex polysaccharides, have been described as elicitors of plant defense responses against the pectinolytic bacteria. Some natural elicitors are produced by biocontrol bacteria (28)(29)(30)(31)(32)(33)(34). So far, only a few bacteria and bacteriophages are described as predators of Dickeya and Pectobacterium (14,35).…”

Development of protection tools targetingDickeya species is an important issue in the potato production. Here, we present the identification and the characterization of novel biocontrol agents. Successive screenings of 10,000 bacterial isolates led us to retain 58 strains that exhibited growth inhibition properties against several Dickeya sp. and/or Pectobacterium sp. pathogens. Most of them belonged to the Pseudomonas and Bacillus genera. In vitro assays revealed a fitness decrease of the tested Dickeya sp. and Pectobacterium sp. pathogens in the presence of the biocontrol agents. In addition, four independent greenhouse assays performed to evaluate the biocontrol bacteria effect on potato plants artificially contaminated with Dickeya dianthicola revealed that a mix of three biocontrol agents, namely, Pseudomonas putida PA14H7 and Pseudomonas fluorescens PA3G8 and PA4C2, repeatedly decreased the severity of blackleg symptoms as well as the transmission of D. dianthicola to the tuber progeny. This work highlights the use of a combination of biocontrol strains as a potential strategy to limit the soft rot and blackleg diseases caused by D. dianthicola on potato plants and tubers. The Pectobacterium and Dickeya pectinolytic bacteria are phytopathogens responsible for several macerating diseases on a wide range of crop and ornamental plants (1-3). The damage caused by these pathogens remains an important issue in many countries worldwide. In Europe, the pectinolytic pathogens on potato crops include Pectobacterium atrosepticum, Pectobacterium carotovorum subsp. carotovorum, Dickeya dianthicola, and Dickeya solani (4-8). Recently, new Pectobacterium taxa, i.e., P. wasabiae and P. carotovorum subsp. brasiliense, have been characterized (2, 9, 10). Pectobacterium sp. populations are qualified as endemic, as their presence has been observed for almost a century in Europe, while the presence of Dickeya spp. as a cause of the symptoms in potato fields was sporadic until the 2000s and the Dickeya sp. damages were probably exclusively due to the species D. dianthicola. In contrast, D. solani seems to have emerged in the 2000s (3).Pectobacterium and Dickeya potato pathogens induce blackleg on stems and soft rot on tubers (11,12). A polyphyletic pathogen population may be isolated from a single sample of symptomatic plant tissues (13). The pathogens penetrate in host plants through natural pores or wounds (i.e., the lenticels, the elongation zones of roots, or insect wounds) as well as mechanical wounds. Insects can act as vectors; surface water and aerosols may also contribute to the dissemination of the pathogens (12, 14-21). Once the pathogens have infected the plant, they may propagate throughout the whole plant and son tubers by the vascular vessels. Losses due to Pectobacterium and Dickeya, related to stem and tuber rot, are major causes for downgrading and rejection of potatoes during seed potato certification. The certification is based on visual inspections in fields or on lots, ranging in Europe from 0 to 4% blackl...
