Description
  • Embryo sac formation is a fundamental step in plant sexual reproduction. However, the key players driving female gametophyte development remain elusive. We show that mutants in CKI1, a gene coding for a putative receptor histidine kinase, prematurely terminate female gametophyte development after completion of all mitotic divisions. CKI1 expression pattern indicates that a chain of molecular and subcellular events resulting in the phenotype manifestation can be triggered concomitantly with completion of meiotic division that yields a functional megaspore. A highly specific CKI1 expression pattern after fertilization suggests a role for CKI1 in early endosperm development as well.
