Partial Resistance to Erwinia carotovora subsp. carotovora and Plant Vigour among F1 Hybrids of Zantedeschia Cultivars
The potential of breeding Zantedeschia cultivars for resistance to soft rot caused by Erwinia carotovora subsp. carotovora (syn. Pectobacterium carotovorum subsp. carotovorum) was determined. Hybrids of six cultivars (‘Back Magic’, Galaxy’, Pink Persuasion’, Sensation’, ‘Treasure’ and ‘Florex Gold’) were screened using a non-destructive resistance test (leaf disk test) and scored different leve...
متن کاملEfficient transformation of Erwinia carotovora subsp. carotovora and E. carotovora subsp. atroseptica.
We used a modified version of the method of Hanahan (D. Hanahan, J. Mol. Biol. 166:557-580, 1983) to transform Erwinia carotovora subsp. carotovora and E. carotovora subsp. atroseptica with the plasmids pBR322, pBR325, and pAT153. The transformation frequency ranged from 1 X 10(2) to 4 X 10(4) colonies per micrograms of plasmid DNA. The nature of these transformants was confirmed by plasmid ana...
متن کاملNATURAL EXTRACTS OF MUSHROOM AND GARLIC AS BACTERICIDE ALTERNATIVES AGAINST POTATO SOFT-ROT BACTERIA, Erwinia carotovora subsp. carotovora
Current study aimed to search for safe and effective natural products to control the potato soft-rot disease, Erwinia carotovora subsp. carotovora. Antibacterial efficiency of edible mushroom extracts (MEs) and garlic essential oil (EO) were compared with two bactericides; streptrol and oxolinic acid as well as two fungicides; mancopper and copper oxychloride. Bioassay experiments were conducte...
متن کاملGenomic diversity of Erwinia carotovora subsp. carotovora and its correlation with virulence.
We used genetic and biochemical methods to examine the genomic diversity of the enterobacterial plant pathogen Erwinia carotovora subsp. carotovora. The results obtained with each method showed that E. carotovora subsp. carotovora strains isolated from one ecological niche, potato plants, are surprisingly diverse compared to related pathogens. A comparison of 23 partial mdh sequences revealed a...
متن کاملRegulation of the expression of prtW::gusA fusions in Erwinia carotovora subsp. carotovora.
Erwinia carotovora subsp. carotovora, a Gram-negative phytopathogenic bacterium, secretes an extracellular metalloprotease, PrtW. Previous results demonstrated that protease activity is necessary for the normal progression of disease symptoms caused by this bacterium. The present study revealed that the prtW gene constitutes an independent transcriptional unit. It is demonstrated that introduct...
