cinnamic acid/glycine max

Organic acids are major water-soluble allelochemicals found in soil infested with quackgrass and are involved in several processes that are important in plant growth and development. This study was carried out to gain more information on the effects of benzoic acid (BEN) andtrans-cinnamic acid (CIN)

A glucosyltransferase, which catalyses the glucosylation of flavonols, using uridine diphosphate-D-glucose as glucose donor, has been isolated and purified about 5-10 fold from cell suspension cultures of soybean (Glycine max L., var. Mandarin). The pH optimum for this reaction was ca. 8.5 in

4-Coumarate:CoA ligase (4CL) is involved in the formation of coenzyme A thioesters of hydroxycinnamic acids that are central substrates for subsequent condensation, reduction, and transfer reactions in the biosynthesis of plant phenylpropanoids. Previous studies of 4CL appear to suggest that many

We have isolated three classes of cDNAs that probably encode three 4-coumarate:coenzyme A ligase (4CL) isoenzymes in soybean (Glycine max L.). The deduced amino acid sequences reveal several regions of extended sequence identity among 4CLs of all plants analyzed to date. The sequences of two of

Cinnamic acid is a known allelochemical that affects seed germination and plant root growth and therefore influences several metabolic processes. In the present work, we evaluated its effects on growth, indole-3-acetic acid (IAA) oxidase and cinnamate 4-hydroxylase (C4H) activities and lignin

Two isoenzymes of p-coumarate: CoA ligase were isolated from cell suspension cultures of soybean (Glycine max L., var. Mandarin). Separation and partial purification of the enzymes were achieved by precipitation with MnCl2 and (NH4)2SO4, and column chromatography on DEAE-cellulose, Sephadex G-100

Ferulic acid, in the form of feruloyl CoA, occupies a central position as an intermediate in the phenylpropanoid pathway. Due to the allelopathic function, its effects were tested on root growth, H(2)O(2) and lignin contents, and activities of cinnamyl alcohol dehydrogenase (CAD, EC 1.1.1.195) and

Benzoic (BEN) and cinnamic (CIN) acids are commonly found in soils and are considered as strong allelochemicals. Published information suggest that BEN and CIN and other phenolic acids decrease plant growth in part by suppressing nutrient absorption. However, studies on the mechanism of action were

We report on the presence of multiple forms of NADPH-cyt P450 reductase in microsomes from higher plants. This contrasts with the animal cyt P450 monooxygenases, where the numerous cyt P450 isoforms are reduced by a single form of reductase. Three NADPH-cyt c reductases have been resolved from

Various benzoic acids (14)C-labelled in para and meta methoxyl groups as well as (O-methyl-(14)C) p-methoxy cinnamic acid were tested for O-demethylation in cell suspension cultures of Phaseolus aureus Roxb. and Glycine max Merr. On the basis of (14)CO2-formation and product analyses the
