[Effect of sodium salicylate on the population dynamics of a rhizospheric strain of Pseudomonas aureofaciens in soil and on wheat roots].
The effect of sodium salicylate on the population dynamics of the rhizobacterium Pseudomonas aureofaciens BS1393 and its variant bearing the naphthalene biodegradation plasmid pBS216 was studied in the wheat rhizoplane and adjacent soil. Optimum salicylate concentration for the maintenance of the plasmid-bearing strain and for the normal growth of wheat was found to be 250 micrograms/g soil. When the soil was supplemented with salicylate, the population of P. aureofaciens BS1393(pBS216) in the wheat rhizoplane and adjacent soil was, respectively, 4- and 20-fold higher than that of the parent strain lacking the plasmid.
