Modulation of transcriptome and metabolome of tobacco by Arabidopsis transcription factor, AtMyb12, leads to insect resistance
Flavonoids synthesised by phenylpropanoid pathway participate in a myriad of physiological and biochemical processes in plants. Due to diversity of secondary transformations and complexity of regulation of branched pathways, single gene strategies have not been much successful in enhancing the accumulation of targeted molecules. We have expressed an
SuperSAGE analysis of the Nicotiana attenuata transcriptome after fatty acid-amino acid elicitation(FAC): identification of early mediators of insect responses
Plants trigger and tailor defense responses after perception of the oral secretions (OS) of attacking specialist lepidopteran larvae. Fatty acid-amino acid conjugates (FACs) in the OS of the Manduca sexta larvae are necessary and sufficient to elicit the herbivory-specific responses in Nicotiana attenuata, an annual wild tobacco species. How FACs are perceived and activate signal transduction mechanisms is unknown.
R2R3-NaMYB8 Regulates the Accumulation of Phenylpropanoid-Polyamine Conjugates, Which Are Essential for Local and Systemic Defense against Insect Herbivores in Nicotiana attenuata
Although phenylpropanoid-polyamine conjugates (PPCs) occur ubiquitously in plants, their biological roles remain largely unexplored. The two major PPCs of Nicotiana attenuata plants, caffeoylputrescine (CP) and dicaffeoylspermidine, increase dramatically in local and systemic tissues after herbivore attack and simulations thereof. We identified NaMYB8, a homolog of
NMR-based metabolomic analysis of plants
Nuclear magnetic resonance (NMR)-based metabolomics has many applications in plant science. Metabolomics can be used in functional genomics and to differentiate plants from different origin, or after
Metabolomic, Transcriptional, Hormonal, and Signaling Cross-Talk in Superroot2
Auxin homeostasis is pivotal for normal plant growth and development. The superroot2 (sur2) mutant was initially isolated in a forward genetic screen for auxin overproducers, and SUR2 was suggested to control auxin conjugation and thereby regulate auxin homeostasis. However, the phenotype was not
Eating at the Table of Another: Metabolomics of Host-Parasite Interactions
The application of metabolomics, the global analysis of metabolite levels, to the study of protozoan parasites has become an important tool for understanding the host-parasite relationship and holds promise for the development of direly needed therapeutics and improved diagnostics. Research advances over the past decade have opened the door for a systems biology approach to protozoan parasites with metabolomics, providing a crucial readout of metabolic activity. In this
