TOR signalling coordinates growth and division to control cell size. Inhibition of Schizosaccharomyces pombe Tor1, in response to a reduction in the quality of the nitrogen source (nutrient stress), promotes mitotic onset through activation of the mitogen-activated protein kinase (MAPK) Sty1 (also known as Spc1). Here we show that ;nutrient starvation' (complete withdrawal of nitrogen or leucin...

Cancer incidence is projected to increase in the future and an effectual preventive strategy is required to face this challenge. Alteration of dietary habits is potentially an effective approach for reducing cancer risk. Assessment of biological effects of a specific food or bioactive component that is linked to cancer and prediction of individual susceptibility as a function of nutrient-nutrie...

Plants frequently have to cope with environments with sub-optimal mineral nutrient availability. Therefore they need to constantly sense changes of ion concentrations in their environment. Nutrient availabilities and needs have to be tightly coordinated between organs to ensure a balance between uptake and demand for metabolism, growth, reproduction, and defense reactions. To this end informati...

Vetiver grass was harvested at 4, 6 and 8-week old re-growth. The chemical composition and quantitative analyses of anti-nutritional components were determined. The result showed that dry matter and fiber content increased with age while crude protein, mineral content and anti-nutritional components reduced with age. It was concluded that age of re-growth significantly affect the nutrient and a...

The fungicide rapamycin increases lifespan in eukaryotes by interfering with the activity of a serine/threonine kinase called TOR (target of rapamycin). TOR complex 1 (TORC1) is an essential integrator of cellular nutrient cues, growth signals and cellular metabolism. Here, we review major components of TORC1, its downstream effectors and lifespan studies in various organisms involving these si...

Autophagy is a catabolic process mediated by incorporation of cellular material into cytosolic membrane vesicles for lysosomal degradation. It is crucial for maintaining cell viability and homeostasis in response to numerous stressful conditions. In this Review, the role of autophagy in both normal biology and disease is discussed. Emphasis is given to the interplay of autophagy with nutrient s...

It is a challenge to breed maize (Zea mays L.) varieties with enhanced levels of protein, oil, starch, and essential amino acid contents while maintaining competitive agronomic capability. We used multivariate statistical procedures to quantify total diversity and its components for 31 physical, biochemical, nutrient, and color traits of 1348 accessions from 13 maize populations. The germplasm ...

The United States Department of Agriculture’s (USDA) National Food and Nutrient Analysis Program (NFNAP) was initiated to update existing component values and to add data on new foods and components to reflect today’s marketplace and needs for data. The USDA Nutrient Database for Standard Reference contains data for about 6040 foods for over 100 compounds. To develop a full nutrient profile for...

Six types of weight changes that occur when food is cooked by different methods are described. For five of these types, true retentions of nutrients (defined as calculations based on nutrient content of known weights of food before and after cooking) were compared with apparent retentions (defined as calculations based on nutrient content of moisture-free raw and cooked foods). Comparisons incl...

Most biological nutrient removal (BNR) wastewater treatment plants are required by permit to significantly reduce total nitrogen (TN) and total phosphorus (TP). In Florida, advanced wastewater treatment (AWT) permit limits are as stringent as 3 mg/L TN and 1 mg/L TP as annual average or maximum month values. Consistently meeting low nutrient permit limits presents several operational challenges...
