Energy resources in plants are managed in continuously changing environments, such as changes occurring during the day/night cycle. Shading is an environmental disruption that decreases photosynthesis, compromises energy status, and impacts on crop productivity. The trehalose pathway plays a central but not well-defined role in maintaining energy balance. Here, we characterized the maize trehal...

BACKGROUND AND AIMS The results of wide- or interploidy crosses in angiosperms are unpredictable and often lead to seed abortion. The consequences of reciprocal interploidy crosses have been explored in maize in detail, focusing on alterations to tissue domains in the maize endosperm, and changes in endosperm-specific gene expression. METHODS Following reciprocal interploidy crosses between d...

new sources of maize resistance to the maize weevil, sitophilus zeamais infestation are indispensable in successful breeding programs against post harvest grain damage. the study investigated the characters and mechanisms that confer resistance to weevil infestation using twenty elite maize genotypes. detailed morphological and physical studies were conducted on whole-maize grain. the grain hul...

Cereal Chem. 73(6):759-761 Total dietary fiber (TDF) was measured by the AOAC method 985.29 hydrolyzed after 30 min, while rice and maize starch remained =42 and using 30 and 60 min of amyloglucosidase incubation. Resistant starch 50%, respectively, of TDF values after 60 min. As expected in the was determined in the TDF residues after gelatinization, dissolution with varietal rices, when amylo...

Glucose syrup is a valuable food ingredient produced by the hydrolysis of starch preferrably from maize. In this study, small-scale production process glucose wheat, maize and potato starches was investigated. Two-step ezymatic using ?–amylase amyloglucosidase for liquefaction saccharification, respectively, analyzed based on content final product. The optimization conditions conducted with dif...

BACKGROUND Diets high in either resistant starch or protein have been shown to aid in weight management. We examined the effects of meals high in non-resistant or resistant starch with and without elevated protein intake on substrate utilization, energy expenditure, and satiety in lean and overweight/obese women. METHODS Women of varying levels of adiposity consumed one of four pancake test m...

The cleaning of food processing plants is essential for ensuring compliance with quality and hygiene standards. Properties food-borne soils such as solubility swelling are relevant provide information concerning their cleanability. In the context processes in industry, aim this study was to determine impact that different fluids exhibit on behaviour consisting amylose- rich native maize, wheat,...

Protein as well as starch is fermented in the colon, but the interaction between protein and starch fermentation and the impact on colonic oncogenesis is unknown. High-protein diets increase delivery of protein to the colon and might promote oncogenesis through generation of toxic products. We investigated the interaction of resistant starch (RS) with digestion-resistant potato protein (PP) on ...

Functions of isoamylase-type starch-debranching enzyme (ISA) proteins and complexes in maize (Zea mays) endosperm were characterized. Wild-type endosperm contained three high molecular mass ISA complexes resolved by gel permeation chromatography and native-polyacrylamide gel electrophoresis. Two complexes of approximately 400 kD contained both ISA1 and ISA2, and an approximately 300-kD complex ...

Sucrose synthase (SuSy) is a highly regulated cytosolic enzyme that catalyzes the conversion of sucrose and a nucleoside diphosphate into the corresponding nucleoside diphosphate glucose and fructose. In cereal endosperms, it is widely assumed that the stepwise reactions of SuSy, UDPglucose pyrophosphorylase and ADPglucose (ADPG) pyrophosphorylase (AGP) take place in the cytosol to convert sucr...
