Assessing the Pathogenic Ability of Ralstonia pseudosolanacearum (Ralstonia solanacearum Phylotype I) from Ornamental Rosa spp. Plants
Ralstonia pseudosolanacearum (Ralstonia solanacearum phylotype I) isolates found in stunted, yellowing, and wilted ornamental rose (Rosa spp.) were assessed for their pathogenic ability in two rose cultivars (cv. "Armando" and cv. "Red Naomi") and in four solanaceous crops: tomato (Solanum lycopersicum cv. "Money Maker"), tobacco (Nicotiana tabacum cv. "White Burley"), eggplant (Solanum melonge...
متن کاملRegulation Involved in Colonization of Intercellular Spaces of Host Plants in Ralstonia solanacearum
A soil-borne bacterium Ralstonia solanacearum invading plant roots first colonizes the intercellular spaces of the root, and eventually enters xylem vessels, where it replicates at high levels leading to wilting symptoms. After invasion into intercellular spaces, R. solanacearum strain OE1-1 attaches to host cells and expression of the hrp genes encoding components of the type III secretion sys...
متن کاملPrevalence of Races and Biotypes of Ralstonia Solanacearum in India
Bacterial wilt caused by Ralstonia solanacearum is the most destructive disease of plants. Fifty-seven isolates of R. solanacearum causing wilt on different host plants viz., tomato (Solanum lycopersicum), brinjal (S. melongena), potato (S. tuberosum), bird of paradise (Strelitzia reginae), ginger (Zingiber officinale), chili (Capsicum annuum), capsicum (Capsicum annuum), davana (Artemisia pall...
متن کاملEvolutionary dynamics of Ralstonia solanacearum.
We investigated the genetic diversity, extent of recombination, natural selection, and population divergence of Ralstonia solanacearum samples obtained from sources worldwide. This plant pathogen causes bacterial wilt in many crops and constitutes a serious threat to agricultural production due to its very wide host range and aggressiveness. Five housekeeping genes, dispersed around the chromos...
متن کاملBreeding for resistances to Ralstonia solanacearum
Ralstonia solanacearum is one of the most devastating bacterial plant pathogens due to its large host range, worldwide geographic distribution and persistence in fields. This soilborne pathogen is the causal agent of bacterial wilt and it can infect major agricultural crops thereby reducing significantly their yield. To favor infection, the bacterium delivers, through the type three secretion s...
