The Jasmonate-Responsive Element from the ORCA3 Promoter from Catharanthus roseus is Active in Arabidopsis and is Controlled by the Transcription Factor AtMYC2 [PDF]

Plant and Cell Physiology, 2011
Jasmonates are plant signaling molecules that play key roles in protection against certain pathogens and against insects by switching on the expression of genes encoding defense proteins including enzymes involved in the biosynthesis of toxic secondary metabolites.

Nano‐enabled stress‐smart agriculture: Can nanotechnology deliver drought and salinity‐smart crops?

Journal of Sustainable Agriculture and Environment, Volume 2, Issue 3, Page 189-214, September 2023., 2023
Salinity and drought stress substantially decrease crop yield and superiority, threatening the world's food security. Nanotechnology holds great potential for designing stress‐smart, sustainable crops to feed the growing population. Abstract Salinity and drought stress substantially decrease crop yield and superiority, directly threatening the food ...

SlERF.H6 mediates the orchestration of ethylene and gibberellin signaling that suppresses bitter‐SGA biosynthesis in tomato

New Phytologist, Volume 239, Issue 4, Page 1353-1367, August 2023., 2023
Summary Steroidal glycoalkaloids (SGAs) constitute a characteristic class of antinutritional metabolites that are found in certain Solanum species. Despite the considerable studies on SGA biosynthesis, the mechanisms of crosstalk between hormone signaling pathways that regulate SGA content still remain to be elucidated.

Overexpression of BcERF3 increases the biosynthesis of saikosaponins in Bupleurum chinense

FEBS Open Bio, Volume 12, Issue 7, Page 1344-1352, July 2022., 2022
An AP2/ERF transcription factor, BcERF3, was identified in an important medicinal plant, Bupleurum chinense. It is dominantly expressed in the root, where it localizes in cell nuclei and is inducible by MeJA. Overexpression of BcERF3 in B. chinense hairy roots caused increased biosynthesis of saikosaponin a, c, and d, accompanied by elevated gene ...

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 [PDF]

Plant Physiology, 2007
Abstract 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 ...
