bacterial wilt of tomato - plant pathology
Ralstonia solanacearum
Ralstonia solanacearum is an aerobic non-spore-forming Gram-negative plant pathogenic bacterium R solanacearum is soil-borne and motile with a polar flagellar tuft It colonises the xylem causing bacterial wilt in a very wide range of potential host plants It is known as Granville wilt when it occurs in tobacco Bacterial wilts of tomato pepper eggplant and Irish

The Plant Pathology Journal
Bacterial traits for virulence of Ralstonia solanacearum causing lethal wilt in plants were extensively studied but are not yet fully understood Other than the known virulence factors of Ralstonia solanacearum this study aimed to identify the novel gene(s) contributing to bacterial virulence of R olanacearum Among the transposon-inserted mutants that were previously

Tomato Bacterial Wilt
Southern bacterial wilt caused by the soilborne bacterium Ralstonia solanacearum (formerly Pseudomonas solanacearum) is a devastating disease of tomatoes The bacterium enters the plant's roots through wounds and colonizes the xylem (or water-conducting tissues) of the plant Disease develops rapidly during the hot days of mid- to late spring

Tomato
The tomato plant produces yellow flowers which can develop into a cyme of 3–12 and usually a round fruit (berry) which is fleshy smoothed skinned and can be red pink purple brown orange or yellow in color The tomato plant can grow 0 7–2 m (2 3–6 6 ft) in height and as an annual is harvested after only one growing season
Bacterial Canker and Wilt in Fresh Market Tomatoes
