13. Carbon Accumulation during Photosynthesis in Leaves of Nitrogen- and Phosphorus-Stressed Cotton
Leaves of cotton (Gossypium hirsutum L.) accumulate considerable dry mass per unit area during photosynthesis. The percentage of C in that accumulated dry mass was estimated as the regression coefficient (slope) of a linear regression relating C per unit area to total dry mass per unit area. Plants were grown on full nutrients or on N- or P-deficient nutrien

14. Lipid-dependent Bidirectional Traffic of Apolipoprotein B in Polarized Enterocytes
Enterocytes are highly polarized cells that transfer nutrients across the intestinal epithelium from the apical to the basolateral pole. Apolipoprotein B (apoB) is a secretory protein that plays a key role in the transepithelial transport of dietary fatty acids as triacylglycerol. The evaluation of the control of apoB traffic by lipids is therefore of partic

15. P Nutrition during Seed Development 1: Leaf Senescence, Pod Retention, and Seed Weight of Soybean
Soybean (Glycine max [L.] Merrill) leaf senescence, which may partially result from mineral redistribution, appears to limit grain yield. Two experiments were designed to test the effects of supplemental inorganic phosphate (Pi), K, malate, and methionine (Met) infusions on senescence and yield. A novel stem infusion technique using pediatric intravenous kit

16. Climate, carbon cycling, and deep-ocean ecosystems
Climate variation affects surface ocean processes and the production of organic carbon, which ultimately comprises the primary food supply to the deep-sea ecosystems that occupy ≈60% of the Earth's surface. Warming trends in atmospheric and upper ocean temperatures, attributed to anthropogenic influence, have occurred over the past four decades. Changes in
