Abstract
Glutamyl-tRNA reductase (GluTR) catalyses the first committed step of tetrapyrrole synthesis, a key regulatory point in the chlorophyll biosynthesis pathway. The objective of the proposed research is to understand how light regulates GluTR expression in Arabidopsis. Expression of GluTR will be analysed by western and northern blotting and by using transgenic Arabidopsis. Expression of GluTR will be analysed by western and northern blotting and by using transgenic Arabidopsis plants expressing chimeric HEMA promoter-GUS fusions. Mutants deficient in light- signalling components will be used to determine which photoreceptors are required for light regulation, what gene products are involved in the light signal transduction pathways and how light interacts with other signals to co-ordinate GluTR expression.
