提取甘薯叶肉细胞的原生质体至今未见报道。虽然Bidney等(1980)提取了甘薯叶柄细胞的原生质体并形成了愈伤组织,但没能提取甘薯叶肉细胞的原生质体。最近,我们不仅提取和培养了甘薯叶肉细胞的原生质体,而且 Protoplasts extracted from sweet potato mesophyll cells have not been reported. Although Bidney et al. (1980) extracted protoplasts from sweet potato petiole cells and formed callus, they failed to extract protoplasts from sweet potato mesophyll cells. Recently, we have not only extracted and cultured protoplasts of sweet potato mesophyll cells, but also
