A chemical inhibitor of jasmonate signaling targets JAR1 in Arabidopsis thaliana.

abstract：:Although the protein synthesis inhibitor cycloheximide (CHX) has been known for decades, its precise mechanism of action remains incompletely understood. The glutarimide portion of CHX is seen in a family of structurally related natural products including migrastatin, isomigrastatin and lactimidomycin (LTM). We found ...
