A module controlling endoreduplication and cell growth in Arabidopsis
Jiang 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…

Grow less or Grow more, That is the Question
Longkumer et al. explore how plant growth is regulated during drought.
