Analyses of chlorogenic acids and related cinnamic acid derivatives from Nicotiana tabacum tissues with the aid of UPLC-QTOF-MS/MS based on the in-source collision-induced dissociation method

Author: Ncube, EN ; Mhlongo, MI ; Piater, LA ; Steenkamp, PA ; Dubery, IA ; Madala, NE Date: Nov 2014 Chlorogenic acids (CGAs) are a class of phytochemicals that are formed as esters between different derivatives of cinnamic acid and quinic acid molecules. In plants, accumulation of these compounds has been linked to several physiological ... Read more
Biotransformation of isonitrosoacetophenone (2-keto-2-phenyl-acetaldoxime) in tobacco cell suspensions

Author: Madala, NE ; Steenkamp, PA ; Piater, LA ; Dubery, IA Date: Jul 2012 Nicotiana tabacum cell suspensions, 2g wet wt/ml, rapidly took up 1 mM isonitrosoacetophenone (INAP), a plant-derived stress metabolite with anti-oxidative and anti-fungal properties, producing 40-hexopyranosyloxy-30-methoxyisonitrosoacetophenone ...

Ergosterol-induced sesquiterpenoid synthesis in tobacco Cells

Author: Tugizimana, F ; Steenkamp, PA ; Piater, LA ; Dubery, IA Date: Feb 2012 Plants have the ability to continuously respond to microbial signals in their environment. One of these stimuli is a steroid from fungal membranes, ergosterol, which does not occur in plants, but acts as a pathogen-associated molecular pattern ... Read more
Metabolomic analysis of isonitrosoacetophenone-induced perturbations in phenolic metabolism of Nicotiana tabacum cells

Author: Madala, NE ; Steenkamp, PA ; Piater, LA ; Dubery, IA Date: Oct 2013 Plants have developed biochemical and molecular responses to adapt to different stress environments. One of the characteristics of the multi-component defence response is the production of defence-related metabolites. Plant defences can be ... Read more
