Transcriptional Co-Repressor Response Of Arabidopsis Thaliana To Different Abiotic Stress, Bhuwan Guragain
University of New Orleans Theses and Dissertations
Plants adapt to the complex environmental challenges by regulating their gene expression. Analyses of plant genomes have identified many genes that are either expressed or repressed during environmental stress. However we do not have much information on gene repression. Transcriptional repression in Arabidopsis thaliana is caused by co-repressors that lack the DNA binding domain and are recruited by transcription factors to regulate target gene expression. The Sridhar lab has identified co-repressors SLK1, SLK2, and LUH, which prevent the expression of stress response genes under non-stress conditions. Arabidopsis transgenic lines expressing the GUS under the control of co-repressor’s promoter were ...
