chinaberry (melia azedarach l.) is a beautiful tree indigenous to the himalayas that grows as a native plant in iran. symptoms similar to bacterial gall have been observed on the crown, shoot and twig of chinaberry, a recent landscape tree since 2003-2004 in shiraz, fars province, south of iran. a gram negative bacterium was isolated from the galls. the isolates did not produce fluorescent pigm...

The relationship of pyoverdins produced by 41 pathovars of Pseudomonas syringae and by phytopathogenic Pseudomonas species was investigated. A high-performance liquid chromatography method for analyzing the culture medium proved to be superior to isoelectric focusing for detecting pyoverdin production, for differentiating slightly different pyoverdins, and for differentiating atypical from typi...

Rubber wood (Hevea brasiliensis) was esterfied with phenylisothiocyanate, and dimensional stability, decay resistance, and photo stability of the modified wood was assessed. The chemically modified wood was characterized by FTIR and CP/MAS C NMR spectroscopy. Unmodified and modified samples were exposed to a brown rot (Polyporus meliae) and a white rot (Coriolus versicolor) fungus for 12 weeks....

The Pseudomonas syringae phylogenetic group comprises 15 recognized bacterial species and more than 60 pathovars. The classification and identification of strains is relevant for practical reasons but also for understanding the epidemiology and ecology of this group of plant pathogenic bacteria. Genome-based taxonomic analyses have been introduced recently to clarify the taxonomy of the whole g...

Meliae Fructus (MF) is the dried ripe fruit of Melia toosendan Siebold et Zuccarini, Meliaceae family. MF is widely used in traditional medicine to treat inflammation and helminthic infection and has anti-bacterial, anti-oxidant, anti-cancer, anti-inflammatory, and analgesic activities. However, potential anti-influenza properties of MF have yet to be investigated. We determined whether an etha...

Approximately 500 fatty acid profiles were prepared for 340 strains of plant-pathogenic and other bacteria currently or recently classified in the genus Pseudomonas Migula 1984. Strains representing some infraspecific taxa were included. The fatty acid profiles were stable and reproducible provided that cultural and chemical techniques were standardized. The 2and 3-hydroxy fatty acids were foun...
