Abstract
The photoperiodic control of flowering is thought to be mediated by a circadian rhythm of sensitivity to light. In support for this hypothesis, we have identified flowering time mutants of Arabidopsis with altered circadian clock properties. The late elongated hypocotyl (lhy) mutant shows phenotypes indicative of poor light reception and is much later flowering than wild-type plants. We have obtained evidence that LHY plays an essential role in circadian clock mechanisms. This grant proposal aims to test whether LHY functions as a cog of the circadian clock or whether altered light signal transduction pathways result in aberrant clock function. In addition, we will determine whether the flowering phenotype is a direct consequence of the disruption of circadian rhythms in the lhy mutant, or whether it results from the constitutive inhibition of a light-dependent, floral promoting pathway.
