NINJA connects JAZ proteins to the co-repressor TOPLESS


ABSTRACT: NINJA (At4g28910) and TOPLESS proteins function as negative regulators of jasmonate responses. Our results point to TPL proteins as general co-repressors that affect multiple signalling pathways through the interaction with specific adaptor proteins. This new insight reveals how stress- and growth-related signalling cascades use common molecular mechanisms to regulate gene expression in plants. Two-condition experiment, Col-0 vs. plants silencing NINJA (RNAi-NINJA) and both Col-0 vs RNAi NINJA treated with coronatine . Biological replicates: 4 control replicates untreated , 4 RNAi NINJA untreated replicates, 4 control treated replicates and 4 RNAi NINJA treated replicates

Jasmonoyl-isoleucine (JA-Ile) is a plant hormone that regulates a broad array of plant defence and developmental processes. JA-Ile-responsive gene expression is regulated by the transcriptional activator MYC2 that interacts physically with the jasmonate ZIM-domain (JAZ) repressor proteins. On perception of JA-Ile, JAZ proteins are degraded and JA-Ile-dependent gene expression is activated. The molecular mechanisms by which JAZ proteins repress gene expression remain unknown. Here we show that th  ...[more]
