A subcellular fraction prepared from fetal rat brain and enriched in growth cone membranes is analyzed for its lectin-binding proteins. Growth-associated glycoproteins are identified by comparing the growth cone glycoproteins with those of synaptosomes. Protein was resolved in one- or two-dimensional gels, electroblotted, and blots probed with radioiodinated concanavalin A, wheat germ agglutini...

Diel (24 h) leaf growth patterns were differently affected by temperature variations and the circadian clock in several plant species. In the monocotyledon Zea mays, leaf elongation rate closely followed changes in temperature. In the dicotyledons Nicotiana tabacum, Ricinus communis, and Flaveria bidentis, the effect of temperature regimes was less obvious and leaf growth exhibited a clear circ...

Phytoremediation is an attractive alternative to conventional treatments of soil due to advantages such as low cost, large application areas, and the possibility of in situ treatment. This study presents the assessment of phytoremediation processes conducted under controlled experimental conditions to evaluate the ability of Ricinus communis L., tropical plant species, to promote the degradatio...

Ricinus communis is a non-food plant, one of the main products of the plant are the seeds from which castor oil is extracted. Castor oil pyrolysis produces heptaldehyde and undecylenic acid. A kinetic model of this reaction is not reported in the literature. The simulation and economic evaluation of this process are not possible without an appropriate kinetic and thermodynamic model. A pseudo-f...

A transformation-sensitive membrane glycoprotein with a subunit molecular weight of 170,000 (170K), a M, = 56,000 protein identified as an “intermediate filament forming protein” (IFP) of hamster embryo fibroblasts, and possible interaction of these two components are described. The 170K glycoprotein has been characterized as follows: 1) weak surface labeling by either lactoperoxidase-catalyzed...

Brinjal shoot and fruit borer, Leucinodes orbonalis Guenee is a major pest. The frequent use of toxic chemical insecticides ultimately poses problem due to pollution the environment, health hazards, adverse effects on beneficial organisms. Hence, current researches looked into efficacy various botanicals against brinjal pests. This experiment was carried out see how ethyl acetate methanol extra...

Lignocellulosic biomass is a source of carbohydrates that can be used in the production biogas. The aim this study was to obtain biogas from waste (leaves, stems and seed bagasse) Ricinus communis, applying pretreatments such as temperature humidity. We examined effect these on biomass, two enzymatic (cellulase cellobiohydrolase), chemicals (NaOH HCl) controls (dried castor straw methane conten...

In Indian system of medicines, root of Ricinus communis Linn. is used to treat inflammation and liver disorders. In present study, the ME of root was prepared by soxhlet method. ME was fractionated into four fractions; explicitly, chloroform, ethyl acetate, n-butanol, and remaining aqueous fraction. The n-butanol fraction, having showed significant inhibition of inflammation, was subjected to f...

The binding of iodinated wheat germ agglutinin, Ricinus communis agglutinin, and concanavalin A to mycoplasma cells and membranes was examined. All mycoplasmas studied specifically bound concanavalin A or R. communis agglutinin and, to a lesser degree, wheat germ agglutinin. The binding of lectins to whole cells was similar to that recorded for membranes, suggesting that significant binding on...
