Detection of phlD gene in some fluorescent pseudomonads isolated from Iran and its relative with antifungal activities.

Fluorescent pseudomonads that produce antibiotic 2,4-diacetylphloroglocinol (2,4-DAPG) are important group of PGRP that inhibit a broad spectrum of plant pathogenic fungi. Studying on genetic diversity of 2,4-diacetylphloroglucinol-producing fluorescent pseudomonads has been shown with special importance. The first step to investigate the genetic diversity of these bacteria is detecting of the genes required for the biosynthesis of this antibiotic.
