Rice Mutants Resistant to Amino Acids and Amino Acid Analogs
Despite the fact that rice is one of the easily manipulated cereals in tissue culture whereby plants can be readily regenerated from anther cultures (Niizeki and Oono 1968), from callus cultures (Nishi et al. 1968), and from protoplasts prepared from suspension cultures (Fujimura et al. 1985), only a very limited amount of selection for resistance to amino acids or amino acid analogs has been reported. One would think that rice could be improved in several ways by selecting for amino acid analog resistance since most resistant mutants overproduce the corresponding natural amino acid.
