Change of phenylalanine ammonia-lyase activity in strawberry leaves infested with the two-spotted spider mite, Tetranychus urticae Koch (Acarina: Tetranychidae)

In a previous paper (Inoue and Sugiura, 1984) the authors suggested that mite-induced physiological changes in host strawberry might influence the population of two-spotted spider mite T. urticae . But there is no evidence of changes in secondary plant metabolite levels induced by infestation in the...

Zusammenfassung:	In a previous paper (Inoue and Sugiura, 1984) the authors suggested that mite-induced physiological changes in host strawberry might influence the population of two-spotted spider mite T. urticae . But there is no evidence of changes in secondary plant metabolite levels induced by infestation in the mite-strawberry system. Phenylalanine ammonia-lyase (EC. 4, 3, 1, 5), (PAL) catalyzes the deamination of phenylalanine to trans-cinnamic acid, one of the most important precursors of secondary plant metabolites. This report shows that PAL activity in mite-infested leaves increases rapidly.
