Journal ArticleDOI
Stress-Induced Accumulation of DcAOX1 and DcAOX2a Transcripts Coincides with Critical Time Point for Structural Biomass Prediction in Carrot Primary Cultures (Daucus carota L.).
M. Doroteia Campos,Amaia Nogales,Hélia Cardoso,Sarma Rajeev Kumar,Sarma Rajeev Kumar,Tânia Nobre,Ramalingam Sathishkumar,Birgit Arnholdt-Schmitt +7 more
TL;DR: A dynamic and correlated expression of carrot AOX genes (DcAOX1 and D cAOX2a) during PCS lag phase and during exponential growth is reported, which point to DcA Ox 1 and DcOx2a as being reasonable candidates for functional marker development related to early cell reprogramming.
Journal ArticleDOI
A WRKY transcription factor from Withania somnifera regulates triterpenoid withanolide accumulation and biotic stress tolerance through modulation of phytosterol and defense pathways
Anup Kumar Singh,Sarma Rajeev Kumar,Varun Dwivedi,Avanish Rai,Shaifali Pal,Ajit Kumar Shasany,Dinesh A. Nagegowda +6 more
TL;DR: While WsWRKY1 silencing in W. somnifera compromised the tolerance to bacterial growth, fungal infection, and insect feeding, its overexpression in tobacco led to improved biotic stress tolerance, demonstrating its importance as a metabolic engineering tool for simultaneous improvement of triterpenoid biosynthesis and plant defense.
Journal ArticleDOI
Precursor feeding studies and molecular characterization of geraniol synthase establish the limiting role of geraniol in monoterpene indole alkaloid biosynthesis in Catharanthus roseus leaves
Krishna Kumar,Sarma Rajeev Kumar,Varun Dwivedi,Avanish Rai,Ashutosh K. Shukla,Karuna Shanker,Dinesh A. Nagegowda +6 more
TL;DR: Feeding of C. roseus leaves with geraniol, but not tryptophan, increased the accumulation of the MIAs catharanthine and vindoline, indicating the limitation of Geraniol in MIA biosynthesis, and demonstrated that the transcriptional regulation of CrGES plays crucial role in MIA BIOSynthesis.
Journal ArticleDOI
Terpene Moiety Enhancement by Overexpression of Geranyl(geranyl) Diphosphate Synthase and Geraniol Synthase Elevates Monomeric and Dimeric Monoterpene Indole Alkaloids in Transgenic Catharanthus roseus.
TL;DR: Improved availability of early precursors for terpene moiety biosynthesis enhanced production of MIAs in C. roseus at the whole plant level through transgenic approaches, the first report demonstrating enhanced accumulation of monomeric and dimeric MIAs including root MIA ajmalicine.
Journal ArticleDOI
Transcriptomic insight into terpenoid and carbazole alkaloid biosynthesis, and functional characterization of two terpene synthases in curry tree (Murraya koenigii).
Seema Meena,Sarma Rajeev Kumar,Varun Dwivedi,Anup Kumar Singh,Chandan S. Chanotiya,Md. Qussen Akhtar,Krishna Kumar,Ajit Kumar Shasany,Dinesh A. Nagegowda +8 more
TL;DR: The transcriptome data generated in this study will be a great resource and the start point for characterizing genes involved in the biosynthetic pathway of medicinally important carbazole alkaloids.
