The role of root size versus root efficiency in phosphorus acquisition in rice Open
In rice, genotypic differences in phosphorus (P) uptake from P-deficient soils are generally proportional to differences in root biomass or surface area (RSA). It is not known to what extent genotypic variation for root efficiency (RE) exi…

Increased phosphate uptake but not resorption alleviates phosphorus deficiency induced by nitrogen deposition in temperate <i>Larix principis‐rupprechtii</i> plantations Open
Summary The imbalance between nitrogen (N) and phosphorus (P) deposition may shift temperate ecosystems from N‐ to P‐limitation. However, it is unclear how the imbalanced N : P input affects the strategies of plants to acquire P and, there…

Phosphorus Limitation Improved Salt Tolerance in Maize Through Tissue Mass Density Increase, Osmolytes Accumulation, and Na+ Uptake Inhibition Open
Low phosphorus (P) availability and salt stress are two major constraints for maize (Zea mays L.) growth in north China. A combination of salinity and high P rather than low P is more detrimental to the growth of maize. However, little is …
