The effect of biologically active substances from coniferous plants on the L-phenylalanine ammonia lyase and peroxidase activities in wheat leaves

The effect of the preparations produced from needles and wood of various coniferous species on the activities of L-phenylalanine ammonia lyase (PAL; EC 4.3.1.5) and peroxidase (PO; EC 1.11.1.7), the enzymes involved in the development of plant defense response, was studied. It was demonstrated that...

Description
Summary:	The effect of the preparations produced from needles and wood of various coniferous species on the activities of L-phenylalanine ammonia lyase (PAL; EC 4.3.1.5) and peroxidase (PO; EC 1.11.1.7), the enzymes involved in the development of plant defense response, was studied. It was demonstrated that treatment of soft wheat (Triticum aestivum L.) primary leaves with biological preparations produced from coniferous plants caused a transient increase in PAL and PO activities. The induction of these enzyme activities depends on the concentration of preparations and plant immune status. The results obtained suggest that coniferous metabolites are of interest as a source of plant extracts with the elicitor effect, increasing the resistance of plants to phytopathogens and adverse environmental factors.
