Abstract
The molecular pathway of intracellular communication between plastids and the nucleus, and its role in light responses of nuclear gene expression, will be analysed by taking advantage of the unique availability of aplastidic guard cells in the arc6 mutant of Arabidopsis. Using GUS and a newly made GFP construct to report nuclear photogene expression (CAB), we will analyse the basic nature of plastid signalling in relation to the plastid complement (positive versus negative signal, cell autonomy), and the role of this signal in light responses. After generating double mutant combinations, we will further use this system to clearly define the role of GUN and DOC genes previously identified by mutation.
