Abstract:
Exquisitely regulated trafficking and fusion of vesicles is crucial for proper cell function. The molecules that regulate vesicle fusion are highly conserved among eukaryotes, but they have also undergone expansion and specialization within single genomes. With diversity comes the potential for functions in unique cell processes, and recent work in Arabidopsis reveals how a member of the SEC1 family, KEULE, functions in plant cell cytokinesis.
