Abstract (180 words)Stomatal guard cells are formed through a sequence of asymmetric and symmetric divisions in the epidermis of the sporophyte of most land plants. We show that several D-type cyclins are consecutively activated in the stomatal linage in the epidermis ofArabidopsis thaliana. WhereasCYCD2;1andCYCD3;2are activated in the meristemoids early in the lineage,CYCD7;1is activated before the final division.CYCD7;1expression peaks in the guard mother cell, where its transcription is modulated by the FOUR-LIPS/MYB88 transcription factor. FOUR-LIPS/MYB88 interacts with theCYCD7;1promoter and represses CYCD7;1 transcription.CYCD7;1stimulates the final symmetric division in the stomatal lineage, since guard cell formation is delayed in thecycd7;1mutant epidermis and guard mother cell (GMC) divisions infour-lipsmutant guard mother cells are limited by loss of function ofCYCD7;1. Hence, the precise activation of a specific D-type cyclin, CYCD7;1, is required for correct timing of the last symmetric division that creates the stomatal guards cells, andCYCD7;1expression is regulated by the FLP/MYB pathway that ensures cell cycle arrest in the stomatal guard cells.Summary StatementThe formation of paired guard cells in the epidermis of theArabidopsis thalianashoot, requires the activity of the D-type cyclin CYCD7;1 for the normal timing of the final division.
