Abstract Background The native potatoes (Solanum tuberosum subsp. tuberosum L.) grown in Chile (Chiloé) represent a new, unexplored source of endophytes to find potential biological control agents for the prevention of bacterial diseases, like blackleg and soft rot, in potato crops. Result The objective of this study was the selection of endophytic actinobacteria from native potatoes for antagonistic activity against Pectobacterium carotovorum subsp. carotovorum and Pectobacterium atrosepticum, and their potential to suppress tissue maceration symptoms in potato tubers. This potential was determined through the quorum quenching activity using a Chromobacterium violaceaum ATCC 12472 Wild type (WT) bioassay and its colonization behavior of the potato plant root system (S. tuberosum) by means of the Double labeling of oligonucleotide probes for fluorescence in situ hybridization (DOPE-FISH) targeting technique. The results showed that although Streptomyces sp. TP199 and Streptomyces sp. A2R31 were able to inhibit the growth of the pathogens, only the Streptomyces sp. TP199 isolate inhibited Pectobacterium sp. growth and diminished tissue maceration in tubers (p ≤ 0.05). Streptomyces sp. TP199 had metal-dependent acyl homoserine lactones (AHL) quorum quenching activity in vitro and was able to colonize the root endosphere 10 days after inoculation. Conclusions We concluded that native potatoes from southern Chile possess endophyte actinobacteria that are potential agents for the disease management of soft rot and blackleg.

This article describes three distinct sunflower stalk diseases that are caused by pathogens that primarily begin as foliar infections. Included are two similar fungal diseases: Phoma black stem and Phomopsis stem canker, caused by Phoma macdonaldii and two species of Diaporthe (helianthi and gulyae), respectively. The bacterial stalk rot disease caused by Pectobacterium carotovorum subsp. carotovorum and Pectobacterium atrosepticum is also included for comparison. We provide information on how to identify the diseases and distinguish them from each other with signs, symptoms, and biological characteristics of the pathogens. It is important to learn to recognize and differentiate these three diseases, because only one (Phomopsis stem canker) is considered to be economically damaging. Misidentification could result in utilizing unneeded disease management techniques.

ABSTRACT Twenty-one salts were tested for their effects on the growth of Pectobacterium carotovorum subsp. carotovorum and Pectobacterium atrosepticum. In liquid medium, 11 salts (0.2 M) exhibited strong inhibition of bacterial growth. The inhibitory action of salts relates to the water-ionizing capacity and the lipophilicity of their constituent ions.

Extracting Solvent

Crustacean eyestalks are known to contain neurosecretory hormones that inhibit molting, growth and gonadal development. Along this framework, this study was conducted to: screen crude eyestalk extracts from the blue crab Portunus pelagicus for possible growth inhibition on two bacterial pathogens Ralstonia solanacearum and Pectobacterium carotovorum subsp. carotovorum. and determine effective concentrations of the crude extract against the pathogens. The screening was done through bioassay using the top agar inoculation technique with 70% ethanol as the extracting solvent and streptomycin as the positive control. Different concentrations of blue crab extract and streptomycin were obtained using serial dilution.
