Resistance induction in wheat plants by silicon and aphids
Dentre os fatores limitantes da producao triticola brasileira esta o ataque de insetos-praga, podendo-se destacar o pulgao-das-gramineas Schizaphis graminum (Rondani) (Hemiptera: Aphididae). OExpand
Nutrients in the cassava (Manihot esculenta Crantz) leaf meal at three ages of the plant
The contents of some nutrients in CLM from five cultivars at three ages of the plant were investigated in order to select the cultivars and ages with superior levels of these nutrients. Expand
The larval midgut of the cassava hornworm (Erinnyis ello)
The results suggest that the anterior and middle region of the midgut absorbs water, whereas the posterior region secretes it and results in a countercurrent flux of fluid, which is responsible for the enzyme recovery from undigested food before it is expelled. Expand
Antinutrients in the cassava (Manihot esculenta Crantz) leaf powder at three ages of the plant
The lowest contents of antinutrients were observed in the 12-month old plants, except for nitrate and hemagglutinin from which the lowest contents were found for the 17 month old ones. Expand
Distribution and characterization of oligomeric digestive enzymes from Erinnyis Ello larvae and inferences concerning secretory mechanisms and the permeability of the peritrophic membrane
Data support the proposition that amylase is initially an integral protein in the membrane of cytoplasmic vesicles at the apex of the epithelial cells and is subsequently processed to become soluble and is set free into the midgut lumen by exocytosis. Expand
Inhibition of pancreatic lipase by extracts of Baccharis trimera (Less.) DC., Asteraceae: evaluation of antinutrients and effect on glycosidases
In order to confirm the traditional use of Baccharis trimera (Less.) DC., Asteraceae, for the reduction of weight, plant extracts were evaluated on the activity of pancreatic lipase (PL), an enzymeExpand
Differential centrifugation, calcium precipitation, and ultrasonic disruption of midgut cells of Erinnyis ello caterpillars. Purification of cell microvilli and inferences concerning secretory
Subcellular fractions of the cells from the first and last third of midguts from Erinnyis ello caterpillars were obtained by conventional homogenization, followed by differential centrifugation orExpand
Consumption of food and spatial organization of digestion in the cassava hornworm, Erinnyis ello
The results support the hypothesis that digestion starts in the endoperitrophic space under the action of amylase and trypsin and is largely completed in the ectoper itrophic space through the catalytic action of several oligomer and dimer hydrolases. Expand
Comparative analysis of functional nutrients in strawberries of different cultivars in the region of Lavras-MG
The strawberry is a pseudo-fruit highly appreciated by the Brazilian population, and its growing has been being established in the region of Lavras. It is a functional food, because in addition toExpand
Physical properties, substrate specificities and a probable mechanism for a β-d-glucosidase (cellobiase) from midgut cells of the cassava hornworm (Erinnyis ello)
Erinnyis ello midgut cells display a β-d-glucosidase (cellobiase, β-d-glucoside glucohydrolase EC with Mr 129 000 and pI 6.8. The enzyme hydrolyzes β-d-glucosides, β-d-galactosides andExpand
