Details:       "For neither can live while the other survives: Cell
	       death during plant reproductive development"
	       
	       ABSTRACT
	       Programmed cell death (PCD) comprises a variety of
	       actively controlled, genetically encoded self-destruct
	       mechanisms of the cell. While many forms of PCD have
	       been recognized and meticulously dissected in animals,
	       to date only little is known about the molecular control
	       of PCD processes in plants. Nevertheless, plant PCD is
	       an essential component of a plant’s reaction to its
	       biotic and abiotic environment, and a central theme
	       during plant development. Plant reproduction in
	       particular involves many instances of developmentally
	       controlled PCD, and tight spatial and temporal control
	       of PCD in reproductive tissues is crucial for successful
	       fertilization and seed set.
	       
	       We are investigating a selection of cell death events in
	       /Arabidopsis thaliana/ to create knowledge about the
	       molecular mechanisms that control the initiation and
	       execution, as well as the prevention of cell death
	       during plant reproductive development. Candidate PCD
	       events include abortion of unfertilized ovules, central
	       endosperm cell death during mid-seed development, and
	       aleurone cell death during seed germination. To analyze
	       these small, inaccessible, and intricately connected
	       tissues, we developed and adapted several forward and
	       reverse genetics strategies, making the Arabidopsis
	       reproductive tissues accessible for cutting-edge –omics
	       approaches. First results on candidate modulators as
	       well as on the development of ovule and seed specific
	       genetics, cell biological and genomics tools will be
	       presented.
