| Research Abstract |
We showed that BiP, an Hsp70 molecular chaperone in the endoplasmic reticulum, function in the fusions of the outer and inner nuclear membranes of the polar nuclei with different sets of J-domain containing partner proteins during the female gametogenesis of A. thaliana. Live imaging analyses showed that the polar nuclei fusion defect can be recovered during the first endosperm nuclear division after fertilization and that the fusion of sperm nuclei at fertilization is required for proper endosperm proliferation. We also identified candidates of nuclear membrane proteins required for the polar nuclei fusion.
