Abstract
The Arabidopsis multidomain protein SPT5L/KTF1 (which has similarity to the transcript elongation factor SPT5) associates with RNA polymerase V (RNAPV) and is an accessory factor in RNA-directed DNA methylation. The zinc-finger protein SPT4 was found to interact with SPT5L (and SPT5) both in vivo and in vitro. Here, we show that plants depleted of SPT4 relative to wild type display reduced DNA ...
