On the feasibility of N2 fixation via a single-site FeI FeIV cycle: Spectroscopic studies of Fe(N2)Fe, FeIV'N, and related species
The electronic properties of an unusually redox-rich iron system, [PhBP3]FeONx (where [PhBP3] is [PhB(CH2PR2)3] ), are explored by Mössbauer, EPR, magnetization, and density-functional methods to gain a detailed picture regarding their oxidation states and electronic structures. The complexes of primary interest in this article are the two terminal iron(IV) nitride species, [PhBP3]Fe'N (3a) and...
متن کاملAssociation between aflatoxin contamination and N2 fixation in peanut under drought conditions
Traits related to nitrogen fixation may be used as indirect selection criteria foraflatoxin resistance in peanut. The aim of this study was to investigate therelationship between N2 fixation traits and aflatoxin contamination in peanut underdifferent drought conditions. Eleven peanut genotypes were evaluated under threewater regimes for two seasons in the field. Data were observed on kernel inf...
متن کاملInteractions Between Changing pCO2, N2 Fixation, and Fe Limitation in the Marine Unicellular Cyanobacterium Crocosphaera
We examined the physiological responses of steady-state iron (Fe)-replete and Fe-limited cultures of the biogeochemically critical marine unicellular diazotrophic cyanobacterium Crocosphaera at glacial (19 Pa; 190 ppm), current (39 Pa; 380 ppm), and projected year 2100 (76 Pa; 750 ppm) CO2 levels. Rates of N2 and CO2 fixation and growth increased in step with increasing partial pressure of CO2 ...
متن کاملNitrogen Fixation via a Terminal Fe(IV) Nitride.
Terminal iron nitrides (Fe≡N) have been proposed as intermediates of (bio)catalytic nitrogen fixation, yet experimental evidence to support this hypothesis has been lacking. In particular, no prior synthetic examples of terminal Fe≡N species have been derived from N2. Here we show that a nitrogen-fixing Fe-N2 catalyst can be protonated to form a neutral Fe(NNH2) hydrazido(2-) intermediate, whic...
متن کاملAssociation of transpiration efficiency with N2 fixation of peanut under early season drought
Peanut is grown mostly in rainfed areas where drought is a recurring problem. Peanut genotypes with high transpiration efficiency (TE) use less water and produced yield better under drought conditions. Specific leaf area and SPAD chlorophyll meter reading are used as surrogate traits for TE. N2 fixation (NF) is also used as a surrogate trait for yield under drought. The objective of this study ...
