Figure 2. Transcript analyses for action of Mmt1. Total leaf RNAs were prepared, and RNA from 2.5 g tissue was blotted to membranes and probed with the atp4 clone pHT160 (Tang et al., 1996a). A. Male-fertile BC11F3 resulting from pollination of A3Tx398 with IS1112C; B. A3Tx398; C. S05-37, #30; D. S05-38, #40; E. S05-36, #167; F. S05-37, #167; G. S05-37, #67; and H. S05-38, #48. The population of 1044-nt transcripts is partially cleaved in the presence of Mmt1, generating the 832-nt transcript.
