Aim: To determine the effect of an AtrbohC mutation on the gene expression pattern in primary root tissue, to identify candidate genes acting downstream of AtrbohC, particularly any encoding antioxidant-related proteins, signal transduction components or proteins known to be required for normal roo...

Our analysis of the sfr6 freezing-sensitive mutant (Knight, H., Veale, E., Warren, G. J. and Knight, M. R. (1999). Plant Cell 11, 875-886.) and cls8 (unpublished) chilling-sensitive mutant of Arabidopsis, has revealed that the expression of certain cold-regulated genes is aberrant in both these mut...

The plant hormone auxin represents an important regulator of growth and development. Significant insight into the mechanisms of auxin action have been obtained from studies of auxin resistant mutants such as aux1 and axr3. The Arabidopsis axr4 mutant was identified in a screen for auxin resistant ro...

The proposal aims to characterise the pathways of DSB repair and recombination in Arabidopsis with the main focus of this research being the NHEJ pathway of illegitimate recombination. We will build on our expertise and resources in the field of DSB repair in plants, using the Arabidopsis NHEJ mutan...

We have been determining signalling components essential for heat tolerance in Arabidopsis thaliana (Larkindale, J., and Knight, M.R. (2002). Protection against heat stress-induced oxidative damage in Arabidopsis involves calcium, abscisic acid, ethylene, and salicylic acid. Plant Physiol 128, 682-6...

Nitric oxide (NO.) is a well-established signal in mammalian cells regulating e.g. smooth muscle tone, neurotransmission and apoptosis. NO interacts with superoxide (O2-) to derive the highly reactive peroxynitrite (ONOO-) radical leading to the generation of lipid hydroxy-peroxides (ROO.) and cell ...
