Deep Minimum and a Vortex for Positronium Formation in Low-Energy Positron-Helium Collisions (open access)

Deep Minimum and a Vortex for Positronium Formation in Low-Energy Positron-Helium Collisions

This article finds a zero in the positronium formation scattering amplitude and a deep minimum in the logarithm of the corresponding differential cross section for positron–helium collisions for an energy just above the positronium formation threshold. Results show that there is a valley in the logarithm of the positronium formation differential cross section that includes the deep minimum and also a minimum in the forward direction.

Fatty acid amide hydrolase and 9-lipoxygenase  modulate cotton seedling growth by ethanolamide  oxylipin levels (open access)

Fatty acid amide hydrolase and 9-lipoxygenase modulate cotton seedling growth by ethanolamide oxylipin levels

Article asserts that polyunsaturated N-acylethanolamines (NAEs) can be hydrolyzed by fatty acid amide hydrolase (FAAH) or oxidized by lipoxygenase (LOX). Altogether, the authors conclude that the growth of cotton seedlings involves fine-tuning of 9-NAE-HOD levels via FAAH-mediated hydrolysis and LOX-mediated production, expanding the mechanistic understanding of plant growth modulation by NAE oxylipins to a perennial crop species.

Inhibition of Very Long Chain Fatty Acids Synthesis Mediates PI3P Homeostasis at Endosomal Compartments (open access)

Inhibition of Very Long Chain Fatty Acids Synthesis Mediates PI3P Homeostasis at Endosomal Compartments

This article uses metazachlor, an inhibitor of VLCFA synthesis, to find that VLCFAs are involved in the TGN/MVB distribution of PI3P. This effect is independent from either synthesis of PI3P by PI3-kinase or degradation of PI(3,5)P2 into PI3P by the SUPPRESSOR OF ACTIN1 (SAC1) phosphatase. Results suggest that PI3P might be transferable from TGN to MVBs and that VLCFAs act in this process.

Ambient urban N deposition drives increased biomass and total plant N in two native prairie grass species in the U.S. Southern Great Plains (open access)

Ambient urban N deposition drives increased biomass and total plant N in two native prairie grass species in the U.S. Southern Great Plains

This article studies atmospheric nitrogen (N) deposition in urban areas on two native prairie grass species, Schizachyrium scoparium and Nasella leucotricha. Findings indicate that while native prairie grasses may exhibit a positive biomass response to increased N deposition up to ~18 kg ha⁻¹ yr⁻¹, total inorganic N deposition is well above the estimated critical load for herbaceous plant species richness in the tallgrass prairie of the Great Plains ecoregion and thus may negatively affect these plant communities.
