Nutrient pollution from nitrogen and phosphorus reduces streams' ability to support aquatic life
Nutrient pollution nitrogen phosphorus reduces aquatic life
2015/3/18
Nutrient pollution from nitrogen and phosphorus in streams has long been known to increase carbon production by algae, often causing nuisance and harmful algal blooms.But according to results of a new...
Stimulation of root acid phosphatase by phosphorus deficiency is regulated by ethylene in Medicago falcata
Phosphorus deficiency Ethylene Medicago falcata Acid phosphatase activity Phosphate transporters Organic phosphorus
2015/2/5
Plants have developed numerous strategies to cope with phosphorus (P) deficiency resulting from low availability in soils. Evolution of ethylene and up-regulation of root secreted acid phosphatase act...
Nitric oxide is involved in phosphorus deficiency-induced cluster-root development and citrate exudation in white lupin
citrate exudation cluster roots nitric oxide phosphorus deficiency white lupin (Lupinus albus)
2015/2/5
White lupin (Lupinus albus) forms specialized cluster roots characterized by exudation of organic anions under phosphorus (P) deficiency. Here, the role of nitric oxide (NO) in P deficiency-induced cl...
Phosphorus deficiency-induced reduction in root hydraulic conductivity in Medicago falcata is associated with ethylene production
Phosphorus deficiency Root hydraulic conductivity Ethylene production Aquaporins Medicago falcata L
2015/2/5
Plants grown in phosphorus-deficient solutions often exhibit disruption of water transport due to reduction in root hydraulic conductivity (Lpr) and enhanced ethylene production. To uncover the relati...
Citrate exudation from white lupin induced by phosphorus deficiency differs from that induced by aluminum
aluminum citrate exudation cluster root phosphorus deficiency white lupin (Lupinus albus)
2015/2/5
Both phosphorus (P) deficiency and aluminum (Al) toxicity induce root exudation of carboxylates, but the relationship between these two effects is not fully understood.Here, carboxylate exudation indu...
Colimitation of the unicellular photosynthetic diazotroph Crocosphaera watsonii by phosphorus, light, and carbon dioxide
Colimitation unicellular photosynthetic diazotroph Crocosphaera watsonii phosphorus, light carbon dioxide
2014/4/2
We describe interactive effects of total phosphorus (total P = 0.1–4.0 μmol L−1; added as H2NaPO4), irradiance (40 and 150 μmol quanta m−2 s−1), and the partial pressure of carbon di...
Standardized Total Tract Digestibility of Phosphorus in Copra Expellers, Palm Kernel Expellers, and Cassava Root Fed to Growing Pigs
Phosphorus Availability Standardized Total Tract Digestibility Swine
2016/5/12
An experiment was conducted to determine the apparent total tract digestibility (ATTD) and standardized total tract digestibility (STTD) of phosphorus (P) in copra expellers (CE), palm kernel expeller...
