S-carvone suppresses cellulase-induced capsidiol production in Nicotiana tabacum by interfering with protein isoprenylation.
S-Carvone has been described as a negative regulator of mevalonic acid (MVA) production by interfering with 3-hydroxy-3-methyl glutaryl coenzyme A reductase (HMGR) activity, a key player in isoprenoid biosynthesis. The impact of this monoterpene on the production of capsidiol in Nicotiana tabacum, an assumed MVA-derived sesquiterpenoid phytoalexin produced in response to elicitation by cellulas...
متن کاملAbscisic acid negatively regulates elicitor-induced synthesis of capsidiol in wild tobacco.
In the Solanaceae, biotic and abiotic elicitors induce de novo synthesis of sesquiterpenoid stress metabolites known as phytoalexins. Because plant hormones play critical roles in the induction of defense-responsive genes, we have explored the effect of abscisic acid (ABA) on the synthesis of capsidiol, the major wild tobacco (Nicotiana plumbaginifolia) sesquiterpenoid phytoalexin, using wild-t...
متن کاملDetermination of capsidiol in tobacco cells culture by HPLC.
Capsidiol is a bicyclic sesquiterpene, which accumulates extracellularly in plants, and has been isolated from many types of Solanaceae. It acts as a phytoalexin produced by Nicotiana tabacum in response to pathogens. Capsidiol has antifungal activity and is formed first in tobacco and pepper plants after infestation. The amount of capsidiol in tobacco cell suspension culture has been previousl...
متن کاملStereospecific hydrogenation of the C-C double bond of enones by Escherichia coli overexpressing an enone reductase of Nicotiana tabacum
We examined the biotransformation of enantiomeric pairs of enones such as pulegone and carvone in recombinant Escherichia coli expressing Nicotiana tabacum pulegone reductase. It was found that recombinant E. coli cells acquired the ability for stereospecific hydrogenation of the exocyclic C=C double bond of pulegone. However, stereospecificity in hydrogenation with the recombinant E. coli cell...

In order to understand the response of tobacco (Nicotiana tabacum L.) to salt stress, the comparative analysis of leaf proteome of Basma S. 31 genotype were performed. Plants were treated with or without 200 mM NaCl for 12 days. The proteins were extracted from leaves, and then separated by two-dimensional electrophoresis. The fresh weight and length of shoot of studied genotype showed greater ...
