Impacts and fate of experimentally enhanced nitrogen deposition on a British lowland heath
, 1998 Between 1989 and 1996, nitrogen, in the form of (NH4)2SO4 (7.7 or 15.4 kg ha-1 year-1), was added to experimental plots of Calluna at a lowland dry heath in the south of England. Background deposition at this site was estimated at between 13-18 kg N ha-1

Food security and sustainable crops production with considering climate change in China
RUDN Journal of Agronomy and Animal Industries, 2019 Increase in the mean seasonal temperature can reduce the duration of many crops which may lead to final yield reduction. China needs to cope with the adverse effects of climate change by developing heat and drought resistant high yielding varieties and ...

FEBS Letters, EarlyView.Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS Letters, EarlyView.Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Assessment of nitrogen uptake and biological nitrogen fixation responses of soybean to nitrogen fertiliser with SPACSYS [PDF]
, 2020 Chemical fertiliser nitrogen addition will inhibit biological nitrogen fixation (BNF) for soybean (Glycine max [L.] Merr) growth. The optimal balance of these two nitrogen input sources has been a key issue for sustainable development in Northeast China.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.
