In this study we have identified the proteins that interacts with LUH by yeast two-hybrid assay. We have isolated the CSTF77 and subunit 7 Pol V mutants and will investigate its role in abiotic stress response. The SLK1, SLK2 and LUH is expressed ubiquitiously in all the plants tissue evidenced by the promoter fusion to the GUS reporter. SLK1, SLK2 and LUH are induced by osmotic, cold and dehydration stress conditions. Furthermore, these proteins are localized in the nucleus of the cell.
