Abstract

In bean leaves infected with tobacco necrosis virus the phenylalanine ammonia-lyase activity dramatically increases parallel with the necrotization process. At the same time the amount of proteins decreases, and the total amount of phenolics increases in the diseased tissues.

Samenvatting

In bonebladeren geïnfecteerd met tabaksnecrosevirus neemt tegelijk met het afstervingsproces de activiteit van fenylalanine ammonia-lyase drastisch toe. Gelijktijdig neemt in de zieke weefsels de hoeveelheid eiwitten af en de totale hoeveelheid fenolen toe.
