ALBA proteins were discovered in Archaea more than 30 years ago. They were gradually identified to be well conserved in Eucaryotes as well. A functional dimeric form of these proteins with DNA and RNA-binding capability was claimed in both mentioned domains of organisms. However, their roles diversified during evolution and vary in between organisms. In Archaea, ALBAs are involved in the genome organization and RNA-protein interactions. In Eukaryotes, there are presented two different subfamilies of ALBA proteins - Rpp20 and Rpp25 subfamily. A sole protein from each subfamily was identified in some organisms though they were multiplied in plants, respectively. These proteins can interact with each other and participate in ontogenetic development and stress responses. According to several studies, ALBA proteins were found to be involved in DNA stability maintenance or pre-rRNA splicing in the nucleus of Arabidopsis thaliana. However, they have been shown to play a role in the cellular metabolism and stress responses in cytoplasm. Six ALBA proteins were identified in the genome of A. thaliana, three from each subfamily. In this study, all heterodimeric protein- protein interactions were investigated by the bimolecular fluorescence complementation (BiFC) assay which revealed positive results in...
