In order to explore the selection of the best auxiliary variables (BAVs) when using the Cokriging method for soil attribute interpolation, this paper investigated the selection of BAVs from terrain parameters, soil trace elements, and soil nutrient attributes when applying Cokriging interpolation to soil nutrients (organic matter, total N, available P, and available K). In total, 670 soil sampl...

SUMMARY Tumor morphogenesis on stems of Lycopersicon eseulen turn, variety Rutgers initiated by Agrobacterium tumefaciens varies with the absence of certain elements from the nutrient solutions. Examinations of the tumors on plants grown in complete and incomplete nutrient solutions revealed different quantities and sizes of vessel elements as well as differences in the quantities of soluble pr...

Transcription from the human asparagine synthetase (A.S.) gene is increased in response to either amino acid (amino acid response) or glucose (endoplasmic reticulum stress response) deprivation. These two independent nutrient-sensing pathways converge on the same set of genomic cis -elements, referred to as nutrient sensing-response elements (NSREs) 1 and 2, within the A.S. promoter. The presen...

We examined individual and interactive effects of two stressors—nutrients (nitrogen [N] and phosphorus [P]) and trace elements (a mix of arsenic [As], copper [Cu], and cadmium [Cd], and in a second experiment also zinc [Zn] and nickel [Ni])—on phytoplankton of the mesohaline Patuxent River, a tributary of Chesapeake Bay. Experiments were conducted in twenty 1-m3 mesocosms. Four mesocosm runs us...
