Control of blackleg and tuber soft rot of potato caused by Pectobacterium and Dickeya species: a review
This paper briefly reviews research on the causative agents of blackleg and soft rot diseases of potato, namely Pectobacterium and Dickeya species, and the disease syndrome, including epidemiological and aetiological aspects. It critically evaluates control methods used in practice based on the avoidance of the contamination of plants, in particular the use of seed testing programmes and the ap...
متن کاملQuorum Sensing Signaling Molecules Produced by Reference and Emerging Soft-Rot Bacteria (Dickeya and Pectobacterium spp.)
BACKGROUND Several small diffusible molecules are involved in bacterial quorum sensing and virulence. The production of autoinducers-1 and -2, quinolone, indole and γ-amino butyrate signaling molecules was investigated in a set of soft-rot bacteria belonging to six Dickeya or Pectobacterium species including recent or emerging potato isolates. METHODOLOGY/PRINCIPAL FINDINGS Using bacterial bi...
متن کاملSoft rot of calla is caused mainly by the bacterium Pectobacterium carotovorum subsp. carotovorum (Pcc)
We studied bacterial isolates 15M and 16M from calla lily tubers showing soft rot in commercial plantations in Poland. Colony morphology differed from that of known agents of bacterial soft rot of this plant. The use of Microgen Bacillus ID system allowed to identify both isolates as Paenibacillus polymyxa. This was confirmed by sequence analysis of 16S rRNA gene fragments. The isolates showed ...
متن کاملStem Rot on Adzuki Bean (Vigna angularis) Caused by Rhizoctonia solani AG 4 HGI in China
During late August and early September 2011, stem rot symptoms were observed on adzuki bean plants (Vigna angularis) growing in fields located in Beijing and Hebei Province, China, respectively. In this study, four isolates were obtained from infected stems of adzuki bean plants. Based on their morphology, and sequence and polymerase chain reaction-restriction fragment length polymorphism (PCR-...
متن کاملBiocontrol of the Potato Blackleg and Soft Rot Diseases Caused by Dickeya dianthicola.
Development of protection tools targeting Dickeya 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 b...
