Carrots are widely grown and enjoyed around the world. Purple carrots accumulate rich anthocyanins in the taproots, while orange, yellow, and red carrots accumulate rich carotenoids in the taproots. Our previous studies indicated that variation in the activity of regulatory genes may be responsible for variations in anthocyanin production among various carrot cultivars. In this study, an R2R3-t...

Four flower-color phenotypes were observed in a population of musk thistle (Carduus tboermeri Weinm.). This plant has been commonly referred to as C. nutans L. The four phenotypes were: purple corolla and purple pollen, pink corolla and white pollen, white corolla and purple pollen, and white corolla and white pollen. In four generations, 177 self-pollinated individuals of these four phenotypes...

In the cell membrane of Halobacteria a photoreceptor protein, bacteriorhodopsin, forms a twodimensional hexagonal crystalline network within the lipid matrix [l-4] . This specialized domain of the membrane has been termed purple membrane [5,6]. Besides its attractiveness for bioenergetic studies, the purple membrane appears highly suited for studying the biogenesis of a membrane: Purple membran...

Two purple textile dyes are referred to in ancient records: one had a blue hue and the other a red.1 The bluish purple was named tekhelet in biblical and Talmudic Hebrew and ‘hyacinthine purple’ by the Romans. The reddish variety was called argaman in the Hebrew and ‘Tyrian purple’ by the Romans. Archaeological findings in the Mediterranean area have indicated that the ancients utilised three s...

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...
