cinnamic acid/arabidopsis

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.

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

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

Cis-cinnamic acid (CA) is one of many cis-phenylpropanoids found in both monocots and dicots. It is produced in planta via sunlight-mediated isomerization of trans-cinnamic acid. This pair of isomers plays a differential role in regulation of plant growth. A functional proteomics approach has been

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

Using the short-lived isotope (11)C (t(1/2) = 20.4 min) as (11)CO(2), we captured temporal changes in whole-plant carbon movement and partitioning of recently fixed carbon into primary and secondary metabolites in a time course (2, 6, and 24 h) following simulated herbivory with the well-known

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

A specific function for peroxisomal β-oxidation in inflorescence development in Arabidopsis thaliana is suggested by the mutation of the abnormal inflorescence meristem 1 gene, which encodes one of two peroxisomal multifunctional proteins. Therefore, it should be possible to identify other

Sunflower (Helianthus annuus L.) is an important oil crop, the secondary metabolites of it include many compounds such as flavonoids and lignin. However, the research on the biosynthesis of phenolic compounds in sunflowers is still scarce. Cinnamate 4-hydroxylase (C4H) belongs to the cytochrome

The fah1 mutant of Arabidopsis is defective in the accumulation of sinapic acid-derived metabolites, including the guaiacyl-syringyl lignin typical of angiosperms. Earlier results indicated that the FAH1 locus encodes ferulate-5-hydroxylase (F5H), a cytochrome P450-dependent monooxygenase (P450) of

A large number of studies have estimated phenylalanine ammonia-lyase (PAL) activity because it strongly reacts to various stimuli. Activity of this enzyme has been assayed mainly by means of spectrophotometry, but the precision of this method is poorly known. We compared assays of PAL activity using

Phenylalanine ammonia-lyase (PAL) is one of the branch point enzymes between primary and secondary metabolism. It plays an important role during plant development and defense. A PAL gene designated as SmPAL1 was cloned from Salvia miltiorrhiza using genome walking technology. The full-length SmPAL1

Eight different P450 sequences were isolated from a cDNA library derived from cultured chickpea cells (cultivar ILC3279) elicited with a Phytophthora sojae (formerly megasperma) elicitor (Pmg-elicitor) by screening with heterologous and homologous probes. Screening with CYP73A1 from Helianthus

Biological synthesis of therapeutic drugs beneficial for human health using microbes offers an alternative production strategy to the methods that are commonly employed such as direct extraction from source organisms or chemical synthesis. In this study, we evaluated the potential for yeast
