Abstract

The work done in this research is an attempt to through the light on identification and record on bacterial gall caused by Pseudomonas meliae L. for the first time in Iraq. The infected plants clearly showed soft and woody gall symptoms with deformed shoots and young stems. The field survey in Duhok plantations obviously obtained diseased transplants with percentage range between 25-88%. The pathogenic bacteria revealed the high host specification on chinaberry and Neem plants (Melia indica). The bacterial colonies on Mac Conkey’s agar media were white creamy in color, circular in growth, dome shaped shiny, and smooth. Analytical Profile Index API20NE demonstrated that three of eight tests were negatives, Nitrate reduction, Indole production, (Tryptophan) and Urease, whereas capable to hydrolyse arginin but didn’t produce levan and non fluorescent. Assimilation tests of ADIpic acid (ADI) and PhenylACetic acid (PAC) were negative, though the bacterial strains were able to utilize glucose (GLU), ARAbinose (ARA), and MANnitol (MAN).
