CelL EliminAtion iN Seeds: Mechanisms and Functions – CLEANSE

Submission summary

The complete developmental elimination of cells is a repeated theme in multicellular organisms. Cell elimination events are particularly prevalent in developing Angiosperm ovules and seeds, suggesting they may represent a useful developmental strategy, requisitioned multiple times during the evolution of these structures. Here we aim to refresh the global understanding of cell elimination in the seed context by focusing on cell elimination in the distal nucellus and in the transient endosperm. Exploiting the power of Arabidopsis as a genetic model with seeds small enough for microscopic visualisation, we will address the genetic regulation of cell elimination, and the cellular mechanisms underlying this process, including how cell elimination is “contained” within specific tissues. We will also explore the physiological functions of cell elimination by testing the hypothesis that cell elimination is an important mechanism underlying sink-source transitions in the developing seed.
