TLDR
There is a general trend in published data towards lower P use efficiency for photosynthetic diazotrophic organisms growing under P limitation with N(2) as their nitrogen source, rather than with NH(4)(+), urea or NO(3)(-).About:

Journal ArticleDOI
Opportunities for improving phosphorus-use efficiency in crop plants.
Erik J. Veneklaas,Hans Lambers,Jason G. Bragg,Patrick M. Finnegan,Catherine E. Lovelock,William C. Plaxton,Charles A. Price,Wolf-Ruediger Scheible,Michael W. Shane,Philip J. White,John A. Raven,John A. Raven +11 more
TL;DR: Improved P-use efficiency can be achieved by plants that have overall lower P concentrations, and by optimal distribution and redistribution of P in the plant allowing maximum growth and biomass allocation to harvestable plant parts.
Journal ArticleDOI
Do plants need nitrate? The mechanisms by which nitrogen form affects plants
TL;DR: It is concluded that the form of N available to plants can affect their time and rate of seed germination, leaf expansion and function, dry matter partitioning between shoot and root, and root architecture.

Arabidopsis Coordinates the Diurnal Regulation of Carbon Allocation and Growth across a Wide Range of Photoperiods

TL;DR: Major correlations were found in the daytime and the night between growth rates and the levels of the sugar-signal trehalose 6-phosphate and the amino acid biosynthesis intermediate shikimate, identifying these metabolites as hubs in a network that coordinates growth with diurnal changes in the carbon supply.

How a phosphorus-acquisition strategy based on carboxylate exudation powers the success and agronomic potential of lupines (Lupinus, Fabaceae)
TL;DR: How common the nonmycorrhizal phosphorus-acquisition strategy based on exudation of carboxylates is in the genus Lupinus is explored, concluding it is very likely more widespread than generally acknowledged.
Journal ArticleDOI
Energy costs of carbon dioxide concentrating mechanisms in aquatic organisms.
TL;DR: Minimum energy (as photon) costs are predicted for core reactions of photosynthesis, for photorespiratory metabolism in algae lacking CO2 concentrating mechanisms (CCMs) and for various types of CCMs; in algae, withCCMs; allowance was made for leakage of CO2 from the internal pool.

The story of phosphorus: Global food security and food for thought
TL;DR: In this article, the authors put forward the case for including long-term phosphorus scarcity on the priority agenda for global food security, and presented opportunities for recovering phosphorus and reducing demand together with institutional challenges.
Journal ArticleDOI
Global analysis of nitrogen and phosphorus limitation of primary producers in freshwater, marine and terrestrial ecosystems.

TL;DR: A large-scale meta-analysis of experimental enrichments shows that P limitation is equally strong across these major habitats and that N and P limitation are equivalent within both terrestrial and freshwater systems.
Journal ArticleDOI
Terrestrial phosphorus limitation: mechanisms, implications, and nitrogen–phosphorus interactions
TL;DR: It is suggested that depletion, soil barriers, and low-P parent material often cause ultimate limitation because they control the ecosystem mass balance of P and cause it to be an ultimate limiting nutrient.
Journal ArticleDOI
The relative influences of nitrogen and phosphorus on oceanic primary production
TL;DR: In this article, the competition between nitrogenfixing and other phytoplankton is inserted into a two-box global model of the oceanic nitrogen and phosphorus cycles, with surface waters more deficient in nitrate than phosphate in the steady state.

Ribo-gnome: the big world of small RNAs
Phillip D. Zamore,Benjamin Haley +1 more
TL;DR: Fifteen years after the discovery of RNA silencing, the authors are only just beginning to understand the depth and complexity of how these RNAs regulate gene expression and to consider their role in shaping the evolutionary history of higher eukaryotes.
