Sulphur and phosphorus transport systems in plants,tion of molecular techniques in nutritional physiology. Genes encoding the transporters involved in the uptake of sulphate and phosphate by plant roots and the distribution of these anions throughout the plant have been identified. Many of these genes have been characterised, their regulatory system

Incorporating rhizosphere processes into field-scale (agro)ecosystem models,tion as a common system and CH. emission as a common focus of interest. The strategies may be characterised as homogeneous (model I; root C deposition is added to the bulk soil compartment), areal (model II; roots contribute via aerenchymatous exchange to an increased soil-atmosphere interfacial sur

Plant-mediated processess to acquire nutrients: nitrogen uptake by rice plants,ulations and experiments are used to assess how uptake is affected by root properties and N transport through the soil. Measurements of the kinetics of N absorption and assimilation and their regulation, and of interactions between NH. and NO. nutrition, are described. It is shown that uptake of N f

Plants and fertilisers as drivers of change in microbial community structure and function in soils,ers might interact with microbial community dynamics in soils. The data presented indicate that although plants and fertilisers do impact on microbial community structure, the relationship between diversity, community structure and function remains complex and difficult to interpret using currently

Soil fungi: diversity and detection,cle. Fungi therefore have many different functions in soils, which include both active roles, such as the degradation of dead plant material, or inactive roles where propagules are present in the soil as resting states. Current knowledge of fungal diversity in soil is based largely on observations o

A key role for pathogenic nematodes in cyclic succession in grazed grassland confirmed similar results in foredune succession. Plants with clonal growth forms appear to be particularly susceptible to pathogenic fungi. A large role for ectomycorrhiza at the

Monitoring temporal and spatial variation in rhizosphere bacterial population diversity: A communitersity and population dynamics of fluorescent pseudomonads, was investigated. Isolates from a collection of over 690 fluorescent pseudomonads, obtained from sugar beet and wheat plants grown in field soils in laboratory microcosms, were genotypically and phenotypically characterised.

Enhancing the biocontrol efficacy of , F113 by altering the regulation and production of 2,4-diacet of the anti-fungal metabolite 2,4-diacetylphloroglucinol (Phl). A genetic approach was used to further enhance the biocontrol ability of Fl 13. Two genetically modified (GM) strains, . F113Rif (pCU8.3) and . F113Rif (pCUP9), were developed for enhanced Ph1 production and assessed for biocontrol eff
