| Description |
A Bacillus cereus strain BS 03 and a Pseudomonas aeruginosa strain
RRLJ 04 were studied for their effect on induction of systemic
resistance against Fusarium udum wilt in pigeon pea, both individually
and in combination with a rhizobial strain RH 2. Split root experiments
confirmed that plants with combination treatment of PGPR and
Rhizobium can survive longer than individual treatments and control. An
increased level of defense-related enzymes, viz., L-phenylalanine
ammonia lyase (PAL), peroxidase (POX) and polyphenol oxidase
(PPO), were also recorded in co-inoculated plants. Production of �-1,3-
glucanase and polymethyl galacturonase by the pathogen in culture
medium was also sharply reduced in presence of both the PGPR
strains. An increased level of phenol content with a decreased level of
nitrogen content was recorded in the leaves of bacterized plants grown
in pathogen infested soil. Presence of BS 03 in the culture medium
stimulated the production of chlamydospore-like structures in the fungal
