CrMYC1, a Catharanthus roseus elicitor- and jasmonate-responsive bHLH transcription factor that binds the G-box element of the strictosidine synthase gene promoter.

A novel jasmonate- and elicitor-responsive element in the periwinkle secondary metabolite biosynthetic gene Str interacts with a jasmonate- and elicitor-inducible AP2-domain transcription factor, ORCA2.

Jasmonate (JA) is an important plant stress hormone that induces various plant defense responses, including the biosynthesis of protective secondary metabolites. The induction of the secondary metabolite biosynthetic gene Strictosidine synthase (Str) in Catharanthus roseus (periwinkle) cells by elicitor requires JA as a second messenger. A 42 bp region in the Str promoter is both necessary and ...

The basic helix-loop-helix transcription factor CrMYC2 controls the jasmonate-responsive expression of the ORCA genes that regulate alkaloid biosynthesis in Catharanthus roseus.

Jasmonates are plant signalling molecules that play key roles in defence against insects and certain pathogens, among others by controlling the biosynthesis of protective secondary metabolites. In Catharanthus roseus, the AP2/ERF-domain transcription factor ORCA3 controls the jasmonate-responsive expression of several genes encoding enzymes involved in terpenoid indole alkaloid biosynthesis. OR...

A jasmonate-responsive promoter element from Catharanthus roseus is active in Arabidopsis thaliana and is controlled by the transcription factor AtMYC2

Identification of a bipartite jasmonate-responsive promoter element in the Catharanthus roseus ORCA3 transcription factor gene that interacts specifically with AT-Hook DNA-binding proteins.

Jasmonates are plant signaling molecules that play key roles in defense against certain pathogens and insects, among others, by controlling the biosynthesis of protective secondary metabolites. In Catharanthus roseus, the APETALA2-domain transcription factor ORCA3 is involved in the jasmonate-responsive activation of terpenoid indole alkaloid biosynthetic genes. ORCA3 gene expression is itself ...

The transient effect of jasmonic acid feeding along with ORCA3 overexpression in Catharanthus roseus hairy roots

Jasmonic acid is an important signaling molecule in plants that regulates a wide variety of cellular responses including the responses to abiotic and biotic stresses. The external application of jasmonic acid has been shown to increase the accumulation of the monomeric terpenoid indole alkaloids, TIAs, in Catharanthus roseus seedlings and hairy root cultures (1-3). Jasmonic acid regulates the e...
