Tremendous progress has been made on molecular aspects of plant phosphorus (P)
nutrition, often without heeding information provided by soil scientists, ecophysiologists, and …

Nitrogen (N) tends to limit plant productivity on young soils; phosphorus (P) becomes
increasingly limiting in ancient soils because it gradually disappears through leaching and …

Background Global phosphorus (P) reserves are being depleted, with half-depletion
predicted to occur between 2040 and 2060. Most of the P applied in fertilizers may be …

Ancient landscapes, which have not been glaciated in recent times or disturbed by other
major catastrophic events such as volcanic eruptions, are dominated by nutrient …

In this study, we reveal a mechanism by which plants regulate inorganic phosphate (Pi)
homeostasis to adapt to environmental changes in Pi availability. This mechanism involves …

Soil phosphate represents the only source of phosphorus for plants and, consequently, is its
entry into the trophic chain. This major component of nucleic acids, phospholipids, and …

Cluster roots are an adaptation for nutrient acquisition from nutrient-poor soils. They develop
on root systems of a range of species belonging to a number of different families (eg …

Over millions of years, terrestrial plants have competed for limited resources, defended
themselves against herbivores, and resisted a myriad of environmental stresses. These …

Proteaceae in southwestern Australia have evolved on some of the most phosphorus-
impoverished soils in the world. They exhibit a range of traits that allow them to both acquire …

Australia harbors some of the most nutrient-impoverished soils on Earth. Southwestern
Australian soils are especially phosphorus (P) impoverished, due to the age of this ancient …
