Anthocyanins are secondary metabolites that contribute to red, blue, and purple colors in plants and are affected by light, but the effects of low light on the physiological responses of purple pak-choi plant leaves are still unclear. In this study, purple pak-choi seedlings were exposed to low light by shading with white gauze and black shading in a phytotron. The responses in terms of photosy...

to evaluate of quantitative and qualitative yield of two basil (ocimum basilicum l.) medicinal plants as affected by planting pattern and plant density, an experiment carried out in factorial arrangement basis on randomized complete block design with three replications. two varieties (green and purple) of basil, two planting patterns (single and double row) and four plant densities (40, 60, 80 ...

in order to determine the effect of different irrigation intervals on some morphophysiological traits of basil (ocimum basilicum l.), an experiment was conducted as factorial based on randomized complete block design with three replications under greenhouse conditions during 2010. treatments included five irrigation intervals with 4, 8, 12, 16 and 20 days intervals and two ecotypes of basil (gr...

The retinylidene chromophore mutant (Y185F) of bacteriorhodopsin, in which Tyr-185 is substituted by phenylalanine, is examined and compared with wild-type bacteriorhodopsin expressed in Escherichia coli; both were reinstituted similarly in vesicles. The Y185F mutant shows (at least) two distinct spectra at neutral pH. Upon light absorption, the blue species (which absorbs in the red) behaves a...

Tree tomato fruits from the yellow giant, giant purple and New Zealand purple cultivars, cultivated in Ecuador were analysed for their phenolic composition and antioxidant capacity. Twelve hydroxycinnamoyl derivatives and four anthocyanins (in the purple cultivars) were detected and identified. The hydroxycinnamoyl derivatives mostly derived from caffeic acid, being 3-O-caffeoylquinic acid and ...

Purple rice (Oryza sativa L. var. indica) cv. Kum Doisaket is cultivated in northern Thailand. This study evaluated the mutagenic and antimutagenic properties of hydrophilic and lipophilic components of purple rice using the Ames test. The seed and hull of purple rice were extracted with hexane, methanol, ethanol, and water. The methanol extracts had the highest amounts of phenolic acids and fl...

similar fashion with tertiaries to give the effect of pure-breeding types if crossing over did not take place. 4 Buchholz, J. T., and Blakeslee, A. F., these PROCEEDINGS, 16, 190-195 (1930). Blakeslee, Albert F. In press, Proceedings of the Sixth International Congress of Genetics. 6 Datura tatula differs from D. stramonium only by the dominant gene for 'purple in contrast to white flowers and ...

Purple-violet gem spinels from Tanzania and Myanmar have been investigated for their gemological, spectroscopic, chemical, colorimetric characteristics. Samples TS MS both had a purple hue with pinkish or brownish secondary tone medium–strong saturation. We identified number of inclusions, including dolomite, phlogopite, forsterite in Tanzanian spinel magnesite, apatite, baddeleyite, anhydrite,...

The majority of lateral flow assays (LFAs) use single-color optical labels to provide a qualitative naked-eye detection, however this detection method displays two important limitations. First, the label makes LFA prone results misinterpretation. Second, it does not allow precise modulation sensitivity and dynamic range test. To overcome these limitations, ratiometric approach is developed. In ...

CMS/Rf systems in rice (Oryza sativa) have long been exploited for hybrid breeding to enhance productivity. Ying xiang CMS/Rf system is a new type. In this study, a mitochondrial comparative proteomic analysis of Ying xiang Sterile Line and its Maintain Line was started for a comprehensive investigation of the mitochondrial proteins’ functions in rice cytoplasmic male sterility. Mitochondria we...
