Sh. Woo et al., Isolation of protoplasts from viable sperm cells of common buckwheat (Fagopyrum esculentum Moench.), CAN J PLANT, 80(3), 2000, pp. 583-585
Protoplasts from sperm cells were isolated. Sperm cells from germinated pol
len placed in solution were released, sieved and removed after sucrose dens
ity gradient centrifugation. The isolated cells were spherical and approxim
ately 5.0-6.0 mu m in diameter. Cytological observations confirmed that spe
rm cells of common buckwheat are true protoplasts.
