Autoradiograph of TD gels of mGing (a) and mPing (b) in anther culture. A single inbred plant of rice cultivar Jiahua No. 1 (Group I, lane 1) was selected as the source of anther culture. The gDNA samples were digested with PstI and ligated to the PstI cassettes for TD. Group I, gDNAs from tiller leaves of 10 randomly selected paddy plants; Group II, gDNAs from 14 anther-derived calli; Group III, gDNAs from 14 independent plantlets regenerated from anther-derived calli. White arrows indicated newly appearing bands.
