Drought is one of the most important environmental factors limiting the cultivation of ornamental plants in the green space. The effects of spermidine and salicylic acid on hollyhock (Alcea rosea L.)under drought stress were investigated. At first, the plants were sprayed with 3 doses of spermidine and 3 doses of salicylic acid (control, 100, 200 and 400 μM) for three consecut...

Nuptial gifts that are manufactured by the male are found in numerous insect species and some spiders, but there have been very few studies of the composition of such gifts. If, as has been proposed recently, nuptial gifts represent sensory traps, males will be selected to produce gifts that are attractive to females but such gifts will not necessarily provide the female with nutritional benefi...

The results presented here show that STC-1 cells, a model of intestinal endocrine cells, respond to a broad range of amino acids, including l-proline, l-serine, l-alanine, l-methionine, l-glycine, l-histidine, and alpha-methyl-amino-isobutyric acid (MeAIB) with a rapid increase in the intracellular Ca(2+) concentration ([Ca(2+)](i)). We sought to identify the mechanism by which amino acids indu...

Transforming growth factor-beta1 (TGF-beta 1) is a multifunctional cytokine that contributes to arterial remodelling by stimulating vascular smooth muscle cell (SMC) growth and collagen synthesis at sites of vascular injury. Since l-proline is essential for the synthesis of collagen, we examined whether TGF-beta 1 regulates the transcellular transport of l-proline by vascular SMCs. l-Proline up...

The physicochemical properties of traditional kochujang added with naked oat flours (0, 5, 10, 15%) were periodically examined during fermentation for 20 weeks at 25°C(± 2 °C). proximate composition roasted as follows: water 0.67%, ash 1.63%, fat 10.37%, protein 13.63%, carbohydrates 73.70%. contents decreased gradually according to the addition level. pH increased level, whereas fermentation. ...

Punch, J. D. (University of Minnesota, St. Paul), J. C. Olson, Jr., and J. V. Scaletti. Amino acid utilization by Alcaligenes viscolactis for growth and slime production. J. Bacteriol. 89:1521-1525. 1965.-The ability of Alcaligenes viscolactis to utilize amino acids in a basal salts solution (K(2)HPO(4), KH(2)PO(4), MgSO(4), MnSO(4), FeSO(4), NaCl) was studied. Of 27 amino acids, only l-asparag...

this study describes the effects of different stocking densities on texture/colour characteristics, protein content /amino acid and lipid content/fatty acid composition of rainbow trout fillet.stocking density was selected 5 (group a), 15 (group b), 25 (group c) kg fish m−3.tukey’s multiple comparison test showed insignificant differences between measured size/weight measurement and condition fac...

Amino acids are the currency of nitrogen exchange between source and sink tissues in plants and constitute a major source of the components used for cellular growth and differentiation. The characterization of a new amino acid transporter belonging to the amino acid permease (AAP) family, AAP11, expressed in the perennial species Populus trichocarpa is reported here. PtAAP11 expression analysis...

Two glutamate derivatives, proline and γ-aminobutyric acid (GABA), appear to play pivotal roles in different aspects of sexual reproduction in angiosperms, although their precise function in plant reproduction and the molecular basis of their action are not yet fully understood. Proline and GABA have long been regarded as pivotal amino acids in pollen vitality and fertility. Proline may constit...
