Distinct cis-elements in the Asparagus officinalis asparagine synthetase promoter respond to carbohydrate and senescence signals

Numai utilizatorii înregistrați pot traduce articole

The Asparagus officinalis L. asparagine (Asn) synthetase (AS) promoter was analysed for elements responding to carbohydrate and senescence signals. Transgenic Arabidopsis thaliana L. plants containing deletion constructs of the -1958 bp AS promoter linked to the β-glucuronidase (GUS) reporter gene

Antihyperglycaemic activity of Asparagus racemosus roots is partly mediated by inhibition of carbohydrate digestion and absorption, and enhancement of cellular insulin action.

Numai utilizatorii înregistrați pot traduce articole

Asparagus racemosus roots have been shown to enhance insulin secretion in perfused pancreas and isolated islets. The present study investigated the effects of ethanol extracts of A. racemosus roots on glucose homeostasis in diabetic rats, together with the effects on insulin action in 3T3

Sucrose delays senescence and preserves functional compounds in Asparagus officinalis L.

Numai utilizatorii înregistrați pot traduce articole

The high metabolic rate of harvested asparagus spears (Asparagus officinalis L.) causes rapid deterioration. To extend shelf life, we investigated the effect of sucrose treatment on asparagus during storage. Asparagus spears were treated with 3%, 5%, and 10% sucrose and stored at 2 °C for 20 h.

Sucrose incubation increases freezing tolerance of asparagus (Asparagus officinalis L.) embryogenic cell suspensions.

Numai utilizatorii înregistrați pot traduce articole

The freezing tolerance of asparagus (Asparagus officinalis L.) embryogenic cells, as determined by electrolyte leakage, was increased by the incubation of samples in medium containing 0.8 M sucrose. To elucidate the mechanism involved, we investigated the changes in soluble carbohydrates, cell

Carbon assimilation, partitioning and export in mature cladophylls of two asparagus (Asparagus officinalis) cultivars with contrasting yield.

Numai utilizatorii înregistrați pot traduce articole

To assess the physiological aspects underpinning cultivar difference in asparagus (Asparagus officinalis L.) yield, diel carbon exchange, carbon partitioning and export and sucrose phosphate synthase (SPS) activity were examined in mature cladophyll tissue of two asparagus cultivars (ASP-69 and

Carbon partitioning and sucrose metabolism in two field-grown asparagus (Asparagus officinalis) cultivars with contrasting yield

Numai utilizatorii înregistrați pot traduce articole

The aim of this study was to investigate the roles of carbon partitioning and sucrose metabolism in regulating cultivar differences in spear yield in asparagus (Asparagus officinalis L.). In the two cultivars studied, maximum net photosynthetic rate (Amax) was positively correlated with sucrose

Decreased expression of fructosyltransferase genes in asparagus roots may contribute to efficient fructan degradation during asparagus spear harvesting

Numai utilizatorii înregistrați pot traduce articole

Asparagus (Asparagus officinalis L.) accumulates inulin and inulin neoseries-type fructans in root, which are synthesized by three fructosyltransferases-sucrose:sucrose 1-fructosyltransferase (1-SST, EC 2.4.1.99), fructan:fructan 1-fructosyltransferase (1-FFT, EC 2.4.1.100), and fructan:fructan

Analysis of the asparagus (Asparagus officinalis) asparagine synthetase gene promoter identifies evolutionarily conserved cis-regulatory elements that mediate Suc-repression

Numai utilizatorii înregistrați pot traduce articole

In asparagus (Asparagus officinalis L.), increased levels of asparagine (Asn) and Asn synthetase (AS) transcript are detected during foliar senescence and in harvested spears, possibly triggered by signals from a reduced supply of carbohydrate. To identify cis-elements mediating this regulation, the

Purification and characterization of novel cationic peroxidases from Asparagus acutifolius L. with biotechnological applications.

Numai utilizatorii înregistrați pot traduce articole

Four novel basic peroxidases, named AaP-1, AaP-2, AaP-3, and AaP-4, were purified from Asparagus acutifolius L. seeds by cation-exchange and gel filtration chromatographies. The four proteins showed a similar electrophoretic mobility of 46 kDa while, by MALDI-TOF MS, different Mr values of 42758.3,

Structure of fructans from excised leaves of New Zealand flax.

Numai utilizatorii înregistrați pot traduce articole

The accumulation of total water-soluble carbohydrate, and specifically sucrose and fructan, by excised leaves of Phormium tenax and P. cookianum (family Phormiaceae J. G. Agardh, order Asparagales) was investigated. Total water-soluble carbohydrate content of excised leaves of P. tenax and P.

Antiulcer and antioxidant activity of Asparagus racemosus Willd and Withania somnifera Dunal in rats.

Numai utilizatorii înregistrați pot traduce articole

Comparative study of the antiulcer and antisecretory activity of Asparagus racemosus Willd (Shatawari) and Withania somnifera Dunal (Ashwagandha) root extract with a standard drug, ranitidine, in various models of gastric ulcer in rats is presented. Ulcer was induced by the indomethacin (NSAID) and

Metabolic regulation of asparagine synthetase gene expression in maize (Zea mays L.) root tips.

Numai utilizatorii înregistrați pot traduce articole

Differential hybridization of a cDNA library constructed with poly(A)+ mRNA from 24 h starved maize (Zea mays L.) root tips, resulted in the isolation of a cDNA (called pZSS1) that was highly induced during glucose deprivation. The nucleotide sequence analysis of the full-length cDNA allowed its

Apoptosis inducing activity of steroidal constituents from Solanum xanthocarpum and Asparagus racemosus.

Numai utilizatorii înregistrați pot traduce articole

A series of Sarsapogenin and Diosgenin derived steroidal constituents (1-12), isolated from Solanum xanthocarpum and Asparagus racemosus were screened for their ability to induce cell death and apoptosis of colon carcinoma cells. The carbohydrate moieties linked to the steroid backbones were found

Analgesic and anti-inflammatory activities of Asparagus africanus root extract.

Numai utilizatorii înregistrați pot traduce articole

The methanolic extract of the roots of Asparagus africanus Lam (Liliaceae) which contains mainly saponins and carbohydrate showed significant analgesic and anti-inflammatory activities (P<0.05) in the tail-flick/hot-plate test and egg albumen-induced rat paw oedema tests that were comparable to the

Antisecretory and antiulcer activity of Asparagus racemosus Willd. against indomethacin plus phyloric ligation-induced gastric ulcer in rats.

Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE To study the antisecretory and antiulcer activity of Asparagus racemosus Willd. (methanolic extract) and its action against indomethacin (a non-steroidal anti-inflammatory drug) plus pyloric ligation (PL)-induced gastric ulcers in rats. METHODS Indomethacin plus PL-induced gastric
