A module controlling endoreduplication and cell growth in Arabidopsis
The Plant Cell: In a NutshellJiang et al. discover a module controlling endoreduplication, a process in which DNA replication occurs in the absence of mitosis.
Background: Organ size is coordinately regulated by both cell number and cell size. Endoreduplication is often associated with cell size in plants and animals, but the…
