摘要：) level. Regulated transcripts involved DIAP1-like gene encoding a death-associated inhibitor of reactive oxygen species (ROS). Other ERF109-regulated transcripts belong to gene families encoding ROS scavenging enzymes and a large number of genes participating in three consecutive pathways, e.g., phenylalanine, tyrosine and tryptophan biosynthesis, tryptophan metabolism and plant hormone signal transduction. We investigated the possibility that ERF109 acts as a "master switch" mediator of a cascade of consecutive events across these three pathways initially by driving expression of ASA1 and YUC2 genes and possibly driving GST, IGPS and LAX2 genes. Action of downstream auxin-regulator, auxin-responsive as well as auxin carrier genes promotes plant cell growth under adverse conditions.
