Phenylalanine ammonia lyases(PALs) are involved in resistance toplant pathogens, but the mechanism by which they contribute toplant immunityis unclear. Two recent studies provide direct evidence for PALs’ contributions to rice broad-spectrum resistance (BSR) mediated by nucleotide-binding domain and le...
Phenylalanine ammonia lyases (PALs) belong to a family of 4‐methylideneimidazole‐5‐one (MIO) cofactor dependent enzymes which are responsible for the conversion of L‐phenylalanine into trans‐cinnamic acid in eukaryotic and prokaryotic organisms. Under conditions of high ammonia concentration, this...
Plants have evolved multiple defense signaling pathways to respond to environment stress and pathogen attack1. The phenylpropanoid pathway is one of the important secondary metabolism pathways and produces a variety of secondary metabolites2,3,4,5,6. Phenylalanine ammonia-lyase (PAL) catalyzes the firs...

A marked rise in the phenylalanine ammonia-lyase activity and the polyphenol synthesis was observed in sliced roots of a sweet potato. The enzyme activity was found to be localized in the root tissue adjacent to the sliced surface. In this region, the synthesis of polyphenols was much higher ...
