Details

Description Erwinia tracheiphila is an economically important plant pathogen of curcurbits (squashes, pumpkins, cucumbers, melons) transmitted by striped cucumber beetles.Cells are Gram negative, rod-shaped, motile bacterium with peritrichous flagella. Facultatively anaerobic. Chemoorganotrophic, having both a repiratory and a fermentative type of metabolism.
Synonyms Bacillus tracheiphilus; Bacterium tracheiphilus;Erwinia amylovora var. Tracheiphila.
Habitat/Source The bacterium can be Isolated from various cucurbits.The bacterium found in United States, Europe, South Africa, Japan, Korea.
Pathogenicity It causes a vascular wilt of Cucurbita species, Cirullus lan- atus, and Cucumis melo. At first dull wilted areas appear on leaves. Later whole leaves and stems wilt, shrivel, and die. Infection is systemic and bacterial ooze is usually obvious at the cut ends of vascular tissues. Erwinia tracheiphila is an economically important plant pathogen of curcurbits (squashes, pumpkins, cucumbers, melons) transmitted by striped cucumber beetles.Once infected, bacteria multiply within the xylem, eventually blocking the vascular system and causing leaves and other tissues to wilt (a condition referred to as bacterial wilt). There are currently no treatments available for infected plants and very few cultivars display resistance to this pathogen. Delineating plant-vector-pathogen interactions at the molecular level are paramount to circumventing disease and developing resistant cultivars and genome sequence is the first step to unraveling how this pathogen is able to evade host plant defenses and invade host tissues.
