Dwarf umbrella trees (Schefflera arboricola) are native to the tropical and subtropical regions of Asia.
As a result, as seen in the PCR studies, isolates of Pseudomonas cichorii cng pith necrosis on tomato, vascular rot in lettuce and leaf spot on dwarf umbrella trees were separated from each other by forming different bands.
The purpose of this study was to isolate and identify of the causal agents of leaf spot disease of tomato, lettuce and dwarf umbrella tree grown in the eastern Mediterranean region of Turkey and to characterize them by morphological, physiological and biochemical tests, ELISA, whole cell fatty acid analysis and pathogenicity tests compared with reference lettuce, tomato and dwarf umbrella tree strains.
In 2002 and 2008, isolations of bacteria were made from typical stem and pith necrosis symptoms on tomato, varnish spot symptoms on lettuce and leaf spot symptoms on dwarf umbrella tree in Adana and Mersin provinces, located in the Eastern Mediterranean region of Turkey.
cichorii strains, isolated from tomato, lettuce and dwarf umbrella tree, were streaked on the amended SPA plates and incubated for 48 h at 25oC and the presence or absence of growth was recorded.
Yedikule) and dwarf umbrella tree (Schefflera arboricola cv.
A total of 12 bacterial strains were isolated and purified from lettuce (3 stras), dwarf umbrella tree (3 strains) and tomato (6 strains) from samples collected in different locations in Adana and Mersin in the eastern Mediterranean region of Turkey.
