摘要


DNA damage occurs in all cells and can hinder chromosome stability and cell viability. Structural Maintenance of Chromosomes5/6 (SMC5/6) is a protein complex that functions as an evolutionarily conserved chromosomal ATPase critical for repairing DNA double-strand breaks (DSBs). However, the mechanisms regulating this complex in plants are poorly understood. Here, we identified the transcriptional coactivator ALTERATION/DEFICIENCY IN ACTIVATION2B (ADA2b) as an interactor of SMC5 in Arabidopsis (Arabidopsis thaliana). ADA2b is a conserved component of the Spt-Ada-Gcn5 acetyltransferase complex, which functions in transcriptional regulation. Characterization of mutant and knockdown Arabidopsis lines showed that disruption of either SMC5 or ADA2b resulted in enhanced DNA damage. Both SMC5 and ADA2b were associated with γ-H2AX, a marker of DSBs, and the recruitment of SMC5 onto DSBs was dependent on ADA2b. In addition, overexpression of SMC5 in the ada2b mutant background stimulated cell death. Collectively, our results show that the interaction between ADA2b and SMC5 mediates DNA repair in plant cells, suggesting a functional association between these conserved proteins and further elucidating mechanisms of DNA damage repair in plants.
