Plant-specific GRAS transcription factors play important roles in regulating growth, development, and stress responses. Castor beans (Ricinus communis) are important non-edible oilseed plants, cultivated worldwide for its seed oils and its adaptability to growth conditions. In this study, we identified and characterized a total of 48 GRAS genes based on the castor bean genome. Combined with phy...

O processo de hidrólise do amido da torta de mamona por ácido e pela combinação de a-amilase, glicoamilase e pululanase foi realizado, seguindo de etapa de fermentação. A hidrólise química resultou em 27.3 g L de açúcares com 33.4% de eficiência de hidrólise. O hidrolisado obtido foi fermentado originando 11 g L de etanol (Y P/S =0.48 g g). A melhor condição de hidrólise enzimática foi (por gra...

This study evaluated, by morphologic and morphometric analyses, the cleaning of apical third of root canals instrumented with nickel-titanium rotary files using different irrigating solutions. Twenty-seven single-rooted mandibular premolars were assigned to three groups (n=9), according to the irrigating solution used: Group I, distilled and deionized water; Group II, 1% NaOCl; and Group III, 3...

Intercropping is one of the important cultural practices in pest management and is based on the principle of reducing insect pests by increasing the diversity of an ecosystem. On-farm experiments were conducted in villages of semi-arid tropical (SAT) India to identify the appropriate combination of castor (Ricinus communis L.) (Malpighiales: Euphorbiaceae) and intercropping in relation to pest ...

The study was carried out to ascertain the antibacterial properties inherent in fermented seed extracts of Ricinus communis. Dry seeds of R. communis (Castor oil plant) were deshelled, grounded to powder, fermented, and then extracted both with alcohol and water using Soxhlet machine. Different concentrations of the extracts were tested against selected bacteria using diffusion method of suscep...

Intact monolayers of L6 myoblasts were treated with neuraminidase, with the aim of selectively removing sialic acid residues of cell-surface glycoproteins. Neuraminidase treatment unmasked binding sites for Ricinus communis agglutinin I and peanut agglutinin, thus allowing the identification of the major binding proteins for these lectins. For Ricinus communis agglutinin I these neuraminidase-s...

1 L-myo-Inositol-1-phosphate synthase (EC 5.5.1.4, MIPS), an evolutionarily conserved enzyme protein, catalyzes the conversion of D-glucose-6-phosphate into 1 L-myo-inositol-1-phosphate (MIP), which is the fi rst and rate-limiting step in the biosynthesis of all inositol-containing compounds (Ray Chaudhuri et al., 1997; Abid et al., 2009). MIPS is found in diverse organisms, both eukaryotic and...

OBJECTIVE To evaluate the antinociceptive activity of the methanol extract of Ricinus communis leaves (MRCL). METHODS Antinociceptive activity was evaluated using acetic acid induced writhing test, formalin induced paw licking and tail immersion method in mice at doses of 100, 125 and 150 mg/kg bw. RESULTS The results indicated that MRCL exhibited considerable antinociceptive activity again...

Wilt caused by Fusarium oxysporum f.sp. ricini (Wr) Gordon is one of the major yield losing diseases in castor. Cultivating wilt resistant cultivars is an effective strategy to control the disease. Utilization of diverse sources of stable resistance is a prerequisite for durable resistance breeding. The experiment was conducted to identify genetically diverse resistant sources in castor germpla...
