Abstract

The aim is to assess and understand physiological and biochemical aspects of stress adaptation by plants, especially their root systems, to environment stress. The principal projects are (i) impact of root stress on hormone transport from roots to shoots in relation to the regulation of plant water relationships, (ii) significance of soil flooding and other factors on the ability of willow to absorb nitrate and herbicide pollutants draining from arable farm land (supported by studentship funded by the Environment Agency), (iii) submergence tolerance in rice, (iv) anaerobic tolerance in the aquatic macrophyte Potamogeton pectinatus (supported by a BBSRC funded CASE student at University of Oxford], (v) programmed cell death and aerenchyma formation in roots of Zea mays (supported by a studentship funded by Oxford-Broookes University). Root to shoot communication studies will concentrate on hormone, nitrate and herbicide fluxes in the transpiration stream and an assessment of their intensity and effectiveness in regulating growth, photosynthesis and transpiration, stomatal closure and leaf epinastic curvature. Work with willow involves nitrate and herbicide uptake studies using plants grown solution culture under controlled conditions. The overall approach emphasises the plant as a whole organism and adopts techniques for studying plant water relationships, hormone levels by immunoassay and mass spectrometry, nutrient uptake, biochemistry and molecular biology as appropriate.
