Identification of Soybean Yield QTL in Irrigated and Rain-Fed Environments
Agronomy, 2021 Drought is the primary abiotic stress that limits yield of soybean (Glycine max (L.) Merr.). The study aimed to identify yield-related quantitative trait loci (QTLs) in soybeans using a population of 160 F4-derived lines from ‘Hutcheson’ × PI 471938 ...

Multireference protonation energetics of a dimeric model of nitrogenase iron-sulfur clusters [PDF]
, 2023 Characterizing the electronic structure of the iron--sulfur clusters in nitrogenase is necessary to understand their role in the nitrogen fixation process. One challenging task is to determine the protonation state of the intermediates in the nitrogen fixing cycle. Here, we use a dimeric iron--sulfur model to study relative energies of protonation at C,

Reconciling cyanobacterial fixed-nitrogen distributions and transport experiments with quantitative modelling [PDF]
Phys. Biol. (2012) 9 016007, 2011 Filamentous cyanobacteria growing in media with insufficient fixed nitrogen differentiate some cells into heterocysts, which fix nitrogen for the remaining vegetative cells. Transport studies have shown both periplasmic and cytoplasmic connections between cells that could transport fixed-nitrogen along the filament.

Fixation of nitrogen with cavitation
Ultrasonics Sonochemistry, 2002 The sonochemical fixation of nitrogen to ammonia was investigated by sonolysis of liquids with nitrogen/hydrogen gas mixtures passing through them. The maximum rate (4 nmol min-1 W-1) was found in water irradiated with 900 kHz ultrasound with gas of a mole fraction 0.6 of nitrogen and the lowest temperature (278 K). Some traces of ammonia were found in
