Profile

The Laboratory of Structural Biology at NIPGR is interested in understanding various plant DNA repair and recombination mechanisms from structural and biochemical perspectives. Recently, we identified At-HIGLE, a GIY-YIG endonuclease, as a possible plant Slx1 with resolve Holliday Junction (four-way DNA molecules) resolving potential.

Current Focus Areas

  • DNA repair and recombination in plants
