Tropical soils are often characterised by low phosphorus availability prompting the view that the productivity of many tropical forests may be phosphorus (P) rather than nitrogen (N) limited. Nevertheless, to date, no study has assessed the mechanisms by which P-deficiency might be limiting rates of photosynthesis in tropical trees. A controlled gl...
It has been shown that under high light (HL) conditions, Arabidopsis bundle sheath cell (BSC) , chloroplasts accumulate hydrogen peroxide (H202) as part of a retrograde signalling network associated with the induction of HL-responsive ASCORBATE PEROXIDASE2 (APX2). It was postulated that this network is mediated by both the "core" abscisic acid (ABA...

Many hydrophobic pollutants can be emitted to agricultural soils if sewage sludge is used as a fertiliser. The fate and effects of pollutants in such receiving environments are relatively poorly understood compared with our knowledge of chemical behaviour and impact in surface waters. One chemical of particular concern is triclosan because it has a...
