EARLY IN SHORT DAYS 7 (ESD7) encodes the catalytic subunit of DNA polymerase epsilon and is required for flowering repression through a mechanism involving epigenetic gene silencing.

Abstract excerpt

We have characterized a mutation affecting the Arabidopsis EARLY IN SHORT DAYS 7 (ESD7) gene encoding the catalytic subunit of DNA polymerase epsilon (epsilon), AtPOL2a. The esd7-1 mutation causes early flowering independently of photoperiod, shortened inflorescence internodes and altered leaf an...
