INFLUENCE OF BACILLUS AMYLOLIQUEFACIENS SUBSP. PLANTARUM IMV B-7404 STRAIN EXOMETABOLITES ON PHENYLALANINE
Abstract:
Influence of Bacillus amyloliquefaciens subsp. plantarum IMV B-7404 strain exometabolites on phenylalanine ammonia-lyase (PAL, EC 4.3.1.24) activity in winter wheat seedlings has been studied. A significant increase of PAL activity at 4-6 hours after treatment of plant roots with Bacillus amyloliquefaciens subsp. plantarum IMVB-7404 strain exometabolites and in case of leaves infection with Bipolaris sorokiniana plant pathogen has been shown. It was established that PAL activity changed along with a decrease of the infected surface area of the leaves evidenced for the induction of response in winter wheat seedlings induced by IMV B-7404 strain exometabolites. It was concluded that the studied exponents could be used as model systems in the research of phytoimmunity induction mechanisms.
