cinnamic acid/arabidopsis thaliana

Trans-cinnamic acid (CA) can be isomerized to cis-CA in Arabidopsis thaliana extract under sunlight. Piperonylic acid treatment of Arabidopsis under ultraviolet (UV) light increased the level of cis-CA in these treated tissues. Similarly, cis-CA was also detected from Oryza sativa seedlings grown

Phenylalanine ammonia lyase (PAL) from Arabidopsis thaliana (AtPAL2) is in general a very good catalyst for the amination of fluoro- and chloro-cinnamic acid derivatives yielding halogenated (S)-phenylalanine derivatives with ≥85% conversion and excellent ee values >99%. We have studied the

Abstract：Salt stress is one of the most common factors limiting plant cultivation. In this study, metabolic responses to salt stress in Arabidopsis thaliana (A. thaliana) leaves were analyzed in situ by neutral desorption-extractive electrospray ionization mass spectrometry (ND-EESI-MS) without any

p-Coumaric acid is a commercially available phenolcarboxylic acid with a great number of important applications in the nutraceutical, pharmaceutical, material and chemical industries. p-Coumaric acid has been biosynthesized in some engineered microbes, but the potential of the plant

Absolute quantitation (iTRAQ) is the latest development in the new quantitative proteomics technology for high-throughput identification and quantitation of proteins. The mechanisms underlying the 4-hydroxy-3-methoxy cinnamic acid ethyl ester treatment in Arabidopsis thaliana was investigated.

A total of eleven alkali-released, aromatic compounds were identified by HPLC, MS and NMR analyses in cell wall extracts from Arabidopsis thaliana roots. Nine of them together constituted the three complete series of 4-hydroxy-, 4-hydroxy-3-methoxy, and 4-hydroxy-3,5-dimethoxy-substituted

This study investigated potential phytotoxic effects on germination and root growth of 21 plant secondary metabolites (sinapinic, syringic, vanillic, ferulic, p-coumaric, chlorogenic, gallic, gentisic, protocatechuic, p-hydroxybenzoic, and trans-cinnamic acids, and eucalyptol, quercetin, vanillin,

We used 5-azido-[7-3H]indole-3-acetic acid (5-azido-[7-3H]IAA), a photoaffinity analogue of the plant hormone indole-3-acetic acid (IAA), to search for auxin-binding proteins in Arabidopsis thaliana membranes. We identified an auxin-binding protein with a molecular mass of 24 kDa (Atpm24) in

The production of natural aroma compounds is an expanding field within the branch of white biotechnology. Three aromatic compounds of interest are cinnamaldehyde, the typical cinnamon aroma that has applications in agriculture and medical sciences, as well as cinnamyl alcohol and hydrocinnamyl

In addition to accumulating biologically active chemicals, plant roots continuously produce and secrete compounds into their immediate rhizosphere. However, the mechanisms that drive and regulate root secretion of secondary metabolites are not fully understood. To enlighten two neglected areas of

Phenylalanine ammonia lyase (PAL) from Arabidopsis thaliana (AtPAL2) was comparatively characterized to the well-studied enzyme from parsley (PcPAL1) and Rhodosporidium toruloides (RtPAL) with respect to kinetic parameters for the deamination and the amination reaction, pH- and temperature optima

Enhanced channeling carbon through pathways: shikimate/chorismate, benzenoid-phenylopropanoid or 2-C-methyl-D-erythritol 4-phosphate (MEP) provides a multitude of secondary metabolites and cell wall components and allows plants response to environmental stresses. Through the biosynthetic pathways,

trans-Cinnamic acid (CA) is a precursor of many phenylpropanoid compounds, including catechins and aroma compounds, in tea (Camellia sinensis) leaves, and is derived from L-phenylalanine (L-Phe) deamination. We have discovered an alternative CA formation pathway from L-Phe via phenylpyruvic acid

Fe deficiency compromises both human health and plant productivity. Thus, it is important to understand plant Fe acquisition strategies for the development of crop plants which are more Fe-efficient under Fe-limited conditions, such as alkaline soils, and have higher Fe density in their edible

Lipopolysaccharides (LPSs), as MAMP molecules, trigger the activation of signal transduction pathways involved in defence. Currently, plant metabolomics is providing new dimensions into understanding the intracellular adaptive responses to external stimuli. The effect of LPS on the metabolomes of
