Role of LEAFLESS, an AP2/ERF family transcription factor, in the regulation of trichome specialized metabolism. [PDF]

New Phytol
Summary Acylsugars, specialized metabolites produced by trichomes of many solanaceous species, provide protection against biotic and abiotic stresses. Many acylsugar metabolic enzymes have been identified; however, regulatory factors remain unknown.

Comparative transcriptomic analysis of genes in the triterpene saponin biosynthesis pathway in leaves and roots of Ardisia kteniophylla A. DC., a plant used in traditional Chinese medicine

Ecology and Evolution, Volume 12, Issue 5, May 2022., 2022
We investigated the genetic basis for the production of triterpenoid saponins in the medicinal plant, Ardisia kteniophylla, using transcriptome sequences and qRT‐PCR. We found that genes involved in late stages of triterpenoid saponin biosynthesis are upregulated in roots, which are traditionally regarded as the medicinal organ of the plant, compared ...

Biosynthesis of Secondary Metabolites Based on the Regulation of MicroRNAs

BioMed Research International, Volume 2022, Issue 1, 2022., 2022
MicroRNA (miRNA), a noncoding ribonucleic acid, is considered to be important for the progression of gene expression in plants and animals by rupture or translational repression of targeted mRNAs. Many types of miRNA regulate plant metabolism, growth, and response to biotic and abiotic factors.

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 ...

BHLH IRIDOID SYNTHESIS 3 is a member of a bHLH gene cluster regulating terpenoid indole alkaloid biosynthesis in Catharanthus roseus

Plant Direct, Volume 5, Issue 1, January 2021., 2021
Abstract Basic helix‐loop‐helix (bHLH) transcription factors (TFs) are key regulators of plant specialized metabolites, including terpenoid indole alkaloids (TIAs) in Catharanthus roseus. Two previously characterized subgroup‐IVa bHLH TFs, BIS1 (bHLH Iridoid Synthesis 1) and BIS2 regulate iridoid biosynthesis in the TIA pathway.

GAME9 regulates the biosynthesis of steroidal alkaloids and upstream isoprenoids in the plant mevalonate pathway [PDF]

, 2016
Steroidal glycoalkaloids (SGAs) are cholesterol-derived molecules produced by solanaceous species. They contribute to pathogen defence but are toxic to humans and considered as anti-nutritional compounds.

Chromium-induced alkaloid production in Catharanthus roseus (L.) G.Don in vitro cultured shoots and related gene expression patterns particularly for the novel gene GS

Acta Agriculturae Slovenica, 2019
This study aimed to determine the effects of methyl jasmonate (Mj) combined with chromium (Cr) as elicitor on production of medicinal alkaloids, its antioxidant potential, and its effects on the expression of signaling and biosynthetic enzymes.

Identification of iridoid glucoside transporters in Catharanthus roseus [PDF]

, 2017
Monoterpenoid indole alkaloids (MIAs) are plant defense compounds and high-value pharmaceuticals. Biosynthesis of the universal MIA precursor, secologanin, is organized between internal phloem-associated parenchyma (IPAP) and epidermis cells ...
