RT-PCR analysis with UGPase1-specific primers. As a result of each RT-PCR using the UGP1-PRT primer set (left) and the UGP1-FRT primer set (right), wild-type (wt) Hwacheong displayed only the expected size fragment in both reactions; whereas the ms-h mutant contained two fragments, one similar to the wt and a second, longer fragment. The same banding pattern was observed in both leaf and panicle. The arrows pointing upwards indicate the fragment size of the wt Hwacheong, and the arrows pointing left represent the fragment size of the ms-h mutant. Abbreviations: FL, fertile leaf; ML: male-sterile leaf; FP, fertile panicle; MP, male-sterile panicle.
