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…

Bypassing reproductive barriers in hybrid seeds
The Plant Cell: In a NutshellHuc et al. discover a method for bypassing the triploid block via chemically induced epimutagenesis using 5-Azacytidine.
Background: Hybridization of plants with different chromosome numbers is often hindered by reproductive barriers established after fertilization. This is because the correct balance…
