daucus blanchei/carbohydrate

Antisera raised against the major hydroxyproline-rich glycoprotein (HRGP) in carrot (Daucus carota L.) taproot, extensin-1, and a minor HRGP, extensin-2, were characterized by western blot analysis, enzyme-linked immunosorbent assay, and periodate oxidation and found to be directed against

Wild carrot (Daucus carota L.) cell suspensions were grown on a mineral salt medium supplemented with 10 mmmyoinositol in the presence and absence of 2.25 mum 2,4-dichlorophenoxyacetic acid (2,4-D), and a variety of carbon sources.The data obtained on growth and embryo number in the absence of 2,4-D

* The influence of carbohydrate availability to mycorrhizal roots on uptake, metabolism and translocation of phosphate (P) by the fungus was examined in axenic cultures of transformed carrot (Daucus carota) roots in symbiosis with Glomus intraradices. * 14C-labelled carbohydrates, 33P-phosphate and

Four biennial species (Arctium tomentosum, Cirsium vulgare, Dipsacus sylvester and Daucus carota) which originate from habitats of different nutrient availability were investigated in a 2-year experiment in a twofactorial structured block design varying light (natural daylight versus shading) and

Cell suspension cultures of Daucus carota were exposed to methyl mercury at concentrations between 0 and 6 micrograms/ml for 1, 3, or 24 hr. Microtubule arrays exhibited no detectable disruption (as compared with controls) when treated with 1, 2, and 3 micrograms/ml methyl mercury. Disorganization

The uptake and utilization of sucrose by embryogenic suspension cultures of carrot (Daucus carota L.) growing in the presence of 2,4-D and by somatic embryos derived from these cultures was monitored using (13)C nuclear magnetic resonance. The exogeneously supplied sucrose was completely hydrolyzed

Application of FT-Raman spectroscopy for simultaneous quantification of carotenoids, carbohydrates, polyacetylenes and phenylpropanoids with high bioactive potential was investigated in storage roots of Daucus carota. Within single FT-Raman experiment carbohydrates, carotenoids, and polyacetylenes

We used a carrot (Daucus carota L. cv. Saint Valery) cell suspension culture as a simplified model system to study the effects of the allelochemical compound coumarin (1,2 benzopyrone) on cell growth and utilisation of exogenous nitrate, ammonium and carbohydrates. Exposure to micromolar levels of

The predominant storage carbohydrates of mature carrot (Daucus carota L.) storage roots typically are the free sugars glucose and fructose. This trait is conditioned by the Rs allele. A naturally occurring recessive mutation, rs/rs, conditions a shift from these reducing sugars to sucrose. RT-PCR

Pectin methylesterases (PMEs) are enzymes produced by bacteria, fungi and higher plants. They belong to the carbohydrate esterase family CE-8. This study deals with comparison of 127 amino acid sequences of this family containing the five characteristic sequence segments: 44_GxYxE, 113_QAVAL,

The salt-extractable hydroxyproline-rich cell wall glycoprotein from carrot (Daucus carota L.) roots is composed of 35% (w/w) protein, 3% (w/w) galactose, and 62% (w/w) arabinose. The arabinose is attached to hydroxyproline as tetra- and trisaccharides. The circular dichroism of the glycoprotein

In response to suboptimal temperatures, temperate annual plants often increase root:shoot ratios, build-up carbohydrates and display typical morphological and anatomical changes. We know less about the responses of biennials such as carrot. As a model plant, carrot has the additional feature of two

This paper presents an approach to simultaneously analyze polyacetylenes, carotenoids, and polysaccharides in carrot (Daucus carota L.) roots by means of Raman spectroscopy. The components were measured in situ in the plant tissue without any preliminary sample preparation. The analysis is based on

A glycoprotein (GP57) was purified by ion-exchange and hydroxylapatite column chromatography from the 70%-ethanol precipitate of culture medium of non-embryogenic carrot cells (Daucus carota L.) grown with 2,4-dichlorophen-oxyacetic acid (2,4-D). Its apparent molecular mass (M r) was estimated to be

Knowing that the element Fe essentially triggers the action of the coconut milk stimulus for the growth of carrot explants and thereafter interacts with added Mo and Mn, the effects of these trace elements on growth (fresh and dry weight) and metabolism of both nitrogenous and nitrogen-free
