Chilling sensitivity of plants is strongly correlated with the presence of high levels of a species of chloroplast phosphatidylglycerol that contains two saturated fatty acids. The most straightforward synthetic pathway for this lipid would require the primary acylation of sn-glycerol 3-phosphate (G3P) with a saturated fatty acid (palmitic acid) rather than with oleic acid, an unsaturated acid....

Genetic diversity and relationships among 6 Amaranthus species from 8 phytogeographic regions of the Indo-Gangetic plains were analyzed using a random amplified polymorphic DNA (RAPD) marker. RAPD primers yielded a total of 262 amplicons, ranging from approximately 250 to approximately 3000 bp in size with an average of 13.1 amplicons per primer, of which 254 amplicons (96.94%) were polymorphic...

Sir,?Since I perused the letter of Baboo Amrito Lall Deb, in your issue of November last, about the beneficial effect of "Amranthus Spinosa" (Kanta Nuteeya) root in Go n orrhoea, I had a strong desire to put it into my practice. As long as I was in charge of the charitable dispensary at .Teh anabad in Gya district I had seen many cases of gonorrhoea, but after a careful investigation I could pr...

over Bengal and the North-Western Provinces. In the latter place it is somewhat scarce in the hot weather, as it dries up by exposure to the powerful rays of the sun, but even then it can be found out there in shady places. In Bengal it is constantly found every where. Cows and rabbits are very fond of the leaves. In milking cows some people believe that it increases the secretion of milk. In t...

India has a rich heritage of medicinal plants, many of which have been explored for the various bioactivities since ages, but the radioprotective potential of the plants have been hardly explored. Since Amaranthus, a common weed and very often eaten as vegetable by rural population, has been used as emollient, astringent, diuretic, blood purifier, hemorrhagic diathesis and biliousness from time...

In order to determine their taxonomic significance, 10 pericarp structure characters were scored for 21 Amaranthus L. taxa. In many, peri carp patterns permit recognition of the taxa as species. Differences between cultivated taxa and their wild relatives offer new arguments against their taxonomic union. The relationships between other closely related taxa are also analyzed (A. quitensis and A...

this study was carried out to determine nutritive value and the effect of amaranthus grain on performance and carcass characteristics of broiler chicks. chemical composition of amaranthus grain including dry matter, crude protein, crude fiber, crude ash, and gross energy were 91.04, 17.50, 8.40, 2.70, 5.41, percent and 4515 kcal/kg respectively. metabolizable energy content of amaranthus grain ...

Effects of red (600 to 680 nanometers) and far red (700 to 760 nanometers) irradiances on Amaranthus retroflexus L. seeds indicate that synthesis of phytochrome in the red-absorbing form takes place in water-imbibed nongerminating seeds at 35 C. After 96 hours in darkness, conversion of about 0.10% phytochrome to the far red-absorbing form induces 50% germination. Continuous far red radiation a...

BACKGROUND AND AIMS Cress-seed (Lepidium sativum) exudate exerts an allelochemical effect, promoting excessive hypocotyl elongation and inhibiting root growth in neighbouring Amaranthus caudatus seedlings. We investigated acidic disaccharides present in cress-seed exudate, testing the proposal that the allelochemical is an oligosaccharin-lepidimoic acid (LMA; 4-deoxy-β-l-threo-hex-4-enopyranuro...

Phytoextraction field experiments were conducted on soil contaminated with 0.39 to 8.7 Bq/g of 137Cs to determine the capacity of five plant species to accumulate 137Cs and the effects of three soil treatments on uptake. The plants tested were redroot pigweed (Amaranthus retroflexus L. var. aureus); a mixture of redroot pigweed and spreading pigweed (A. graecizans L.); purple amaranth (A. crute...
