A Novel Transcription Factor in Arabidopsis thaliana Abiotic Stress Response

Weerathunga Arachchilage, Achira S 18 December 2015 (has links)
Plants respond to environmental stress by altering their gene expression. Under stress conditions some genes are activated and some genes are repressed. Even though a lot of work has been done to understand mechanisms of gene activation under abiotic stress very little information is available on how stress responsive genes are kept repressed under normal growth conditions. Recent work has revealed that plants use transcriptional repression as common mechanism of gene repression. Transcriptional repression is achieved by recruitment co-repressor complexes to the target genes. Recent studies have revealed that the co-repressor LUH complexes with SLK1 and SLK2 to silence Arabidopsis thaliana stress responsive genes. However, the transcription factors involved in the recruitment of this complex to its target genes are not known. In this study, we identified SLK2INT1, as a novel transcription factor that is involved in silencing of select Arabidopsis thaliana stress responsive genes by recruiting the LUH-SLK2 complex.
