tailieunhanh - Ralstonia solanacearum

Ralstonia solanacearum is an aerobic non-sporing, Gram-negative plant pathogenic bacterium. 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 potato caused by Ralstonia solanacearum were among the first diseases that Erwin Frink Smith proved to be caused by a bacterial pathogen. | Ralstonia solanacearum Ralstonia solanacearum is an aerobic non-sporing 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 potato caused by Ralstonia solanacearum were among the first diseases that Erwin Frink Smith proved to be caused by a bacterial pathogen. Because of its devastating lethality R. solanacearum is now of the more intensively studied phytopathogenic bacteria and bacterial wilt of tomato is a model system for investigating mechanisms of pathogenesis. 1 Ralstonia was recently classified as Pseudomonas with similarity in most aspects except that it does not produce fluorescent pigment like Pseudomonas ffi The genome of R. solanacearum Strain GMI1000 has been sequenced. 3 Within the R. solanacearum species complex there are four major monophyletic clusters of strains termed phylotypes that are geographically distinct phylotypes I-IV are found in Asia America Africa and Oceania R. solanacearum was once considered as a possible biological control of Kahili Ginger Hedychium gardne-rianum which is a member of 100 of the World s Worst Invasive Alien Species in 2004. 4 However R. solanacearum is no longer used as a biological control for Kahili Ginger in Hawaiian forests because of its wide host range. The ginger strain infects numerous ginger species including edible ginger Zingiber officinale shampoo ginger Zingiber zerumbet pink ginger Alpinia purpu-rata and red ginger Alpinia purpurata . 5 1 Hosts and symptoms Hosts Plant hosts that R. solanacearum infects includes Crops Potato Solanum tuberosum Tomato Lycopersicum esculentum Aubergine egg plant Solanum me-longena Banana Musa spp Geranium common name Pelargonium Ginger Zingiber officinale Tobacco Nicotiana tabacum Sweet pepper
