Yedikule) and dwarf umbrella tree (Schefflera arboricola cv.
Symptoms of the disease on dwarf umbrella tree plants are characterized by small margins of brown with wide yellow halos on leaves.
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.
Symptoms on dwarf umbrella tree plants were recorded 30 days after inoculation.
Refernce strains (GSPB 2097 and CFPB 2101) were less aggressive on all plants, while reference strain NCPBB 3802 was more aggressive on tomato and lettuce plants but less aggressive on dwarf umbrella tree plants.
988 in dwarf umbrella tree strains at A 405 wavelength.
umbrella tree had 11 different fatty acids that included saturated (12:0, 16:0 and 18:0), unsaturated (11 methyl 18:1 w7c and 18:1 w7c), hydroxyl (10:0 3-OH, 12:0 2OH and 12:0 3OH), cyclopropane (17: CYCLO) and two Sum in Features (3, 7) (Table VII).
For this reason, the lettuce, tomato and dwarf umbrella tree bacterial strains are thought to be of different origin (Fig.
As seen in PCR studies of tomato pith and stem necrosis, lettuce bacterial rot and varnish spot, and dwarf umbrella tree bacterial leaf spot caused by Pseudomonas cichorii, isolates can be differentiated from each other by different PCR band patterns.
A total of 12 bacteria were isolated from leaf spot and midrib rot symptoms on lettuce (3 strains), dwarf umbrella tree (3 strains) and tomato (6 strains) in Adana and Mersin provinces.
In the pathogenicity tests all isolates were screened for the ability to produce symptoms on lettuce, dwarf umbrella tree and tomato.
This is the first report of Pseudomonas cichorii causing serious leaf blight on dwarf umbrella tree.
1992), but the dwarf umbrella tree strains had two different fatty acids (sum in feature and 18:1w7c).
cichorii strains isolated from tomato, lettuce and dwarf umbrella tree plants were identified by classical morphological and biochemical tests.
ABSTRACT Stem and pith necrosis symptoms on tomato, varnish spot symptoms on lettuce and leaf spot symptoms on dwarf umbrella trees were observed in late winter and spring of 2002 and 2008 in the Eastern Mediterranean region of Turkey.
