Abstract
We have discovered clear, repeatable effects of white and red light signals on the labelling pattern of phosphonositides in dormancy-breaking in turions of Spirodela polyrhiza. We propose to test the hypothesis that phosphoinositide headgroup turnover and Ins (1,4,5) P3 are involved in the transduction of light signals by studies of the action spectra, a full analysis of turnover using the labelling patterns of individual compounds from (3H) Ins and (32P) Pi, and binding assays for Ins (1,4,5) P3. The investigation will be extended to other well- characterised light-responses of duckweeds: circadian clock phase re-setting and photoperiodicinduction in Lemna gibba and L. paucicostrata.
