Abstract excerpt
An Arabidopsis mutant named defective repression of OLE3::LUC 1 (drol1) was originally isolated as a mutant with defects in the repression of OLEOSIN3 (OLE3) after seed germination. In this study, we show that DROL1 is an Arabidopsis homolog of yeast DIB1, a subunit of the U5 small nuclear ribonucleoprotein particle (snRNP) in the spliceosome. It is also part of a new subfamily that is specific to a certain class...
