the use of fertilizers in agriculture is a potential source of environmental pollution especially in ‎water quality and soil resources. the study of effective factors on water and nutrient transport ‎through soil profile is helpful for nutrient management to minimize adverse impacts on environment ‎and nitrate leaching below root zone. in this study, for assessing the nitrate transportation bel...

The classic paradigm for in vitro tissue engineering of bone involves the isolation and culture of donor osteoblasts or osteoprogenitor cells within three-dimensional (3D) scaffold biomaterials under conditions that support tissue growth and mineralized osteoid formation. Our studies focus on the development and utilization of new dynamic culture technologies to provide adequate nutrient flux w...

Nutrient sensors and developmental timers are two classes of genes vital to the establishment of early development in the social soil bacterium Myxococcus xanthus. The products of these genes trigger and regulate the earliest events that drive the colony from a vegetative state to aggregates, which ultimately leads to the formation of fruiting bodies and the cellular differentiation of the indi...

Little is known about the adaptability of lychee ( Litchi chinensis ) to acidic soils high in aluminum (Al). A 2-year greenhouse study was conducted determine effects various levels soil Al on dry matter production, plant growth, and nutrient concentration shoots cultivar rootstock seedlings (maternal half-sibs) cultivars Brewster, Bostworth-3 (Kwai May Pink), Kaimana. Soil treatments were stat...
