Experimental warming alters free‐living nitrogen fixation in a humid tropical forest

New Phytologist, EarlyView.
Summary Microbial nitrogen (N) fixation accounts for c. 97% of natural N inputs to terrestrial ecosystems. These microbes can be free‐living in the soil and leaf litter (asymbiotic) or in symbiosis with plants. Warming is expected to increase N‐fixation rates because warmer temperatures favor the growth and activity of N‐fixing microbes.

Computationally Guided Design of a Soluble, Abundant and Functional AnfH Variant for the Expression of Fe‐Only Nitrogenase in Plant Mitochondria

Plant Biotechnology Journal, EarlyView.
Design of more soluble AnfH variants for expression in plant mitochondria. ABSTRACT Engineering nitrogenase directly into crops is a long‐held aspiration in plant biotechnology. Of the three types, the Fe‐only nitrogenase is a promising engineering target, as it has a simpler maturation pathway than the MoFe‐ and VFe‐nitrogenases and does not require ...

The influence of fertilisation and crop rotation on soil microbial characteristics in the long-term field experiment

Plant, Soil and Environment, 2009
Soils were sampled from the plots with four variants of fertilisation: Nil - without fertilisation, NPK - mineral fertilisation, FYM - farmyard manure, FYM + NPK - farmyard manure with mineral fertilisation, and two variants of crop rotation: field IV ...

Nitrogenase Bioelectrocatalysis: From Understanding Electron-Transfer Mechanisms to Energy Applications

ACS Energy Letters, 2018
Nitrogenase is the only enzyme known to reduce molecular nitrogen to ammonia, so it has been an oxidoreductase enzyme of great interest to the electrofuels and catalysis communities, as people consider the design of bioinspired nitrogen reduction ...

Natural Variation of a PPR Coding Gene SST1 Confers Salt Tolerance During Soybean Domestication

Plant Biotechnology Journal, EarlyView.
ABSTRACT Soil salinity is one of the constraints that adversely affect seedling growth and limit soybean yield. Identifying salt tolerance genes and profiling their allele variants are crucial for elucidating the mechanisms underlying salt tolerance in soybean and enabling the genetic improvement of salt‐tolerant cultivars.

Tracing the ‘9th Sulfur’ of the Nitrogenase Cofactor via a Semi-Synthetic Approach

Nature Chemistry, 2018
The M-cluster is the [(homocitrate)MoFe7S9C] active site of nitrogenase that is derived from an 8Fe core assembled viacoupling and rearrangement of two [Fe4S4] clusters concomitant with the insertion of an interstitial carbon and a ‘ninth sulfur ...

Comparative proteomics analysis of root and nodule mitochondria of soybean

Plant, Cell &Environment, EarlyView.
Abstract Legumes perform symbiotic nitrogen fixation through rhizobial bacteroids housed in specialised root nodules. The biochemical process is energy‐intensive and consumes a huge carbon source to generate sufficient reducing power. To maintain the symbiosis, malate is supplied by legume nodules to bacteroids as their major carbon and energy source ...

Tripartite Symbiosis Between Legumes, Arbuscular Mycorrhizal Fungi and Nitrogen Fixing Rhizobia: Interactions and Regulation

Plant, Cell &Environment, EarlyView.
ABSTRACT Legume plants can interact with nitrogen‐fixing rhizobia bacteria and arbuscular mycorrhizal fungi (AMF) simultaneously, forming a tripartite symbiotic association. Co‐inoculation studies performed on a variety of legumes have shown that rhizobia and AMF influence each other when they co‐occur in tripartite association and affect host plant ...

Drought and Herbivory Have Selective Transgenerational Effects on Soybean Eco‐Physiology, Defence and Fitness

Plant, Cell &Environment, EarlyView.
ABSTRACT Soybeans, one of the most important legumes, face multiple stresses including drought and herbivory. But the potential transfer of the interactive effects of these stressors onto the transgenerational plants has not been understood. We hypothesised that progeny from stressed parents will have enhanced ecophysiology and defence traits through ...

Pyrene‐Based Noncovalent Immobilization of Nitrogenase on Carbon Surfaces

ChemBioChem, 2019
Early work with viologen‐mediated nitrogenase bio‐electrochemistry focused on bio‐electrocatalysis with the enzyme in solution, but biocatalyst immobilization at electrode surfaces is favorable as it provides a high effective concentration of biocatalyst
