Transcript Pattern of the psbB-psbT-psbH-petB-petD Transcription Unit and psbN in the Mutants hcf107-1 and hcf107-2.
Eight micrograms of total leaf RNA from 3-week-old mutant and wild-type (WT) seedlings was analyzed in each RNA gel blot hybridization ([A] to [H]). The hybridization probes and their locations are indicated with arrows and letters (A to H) at the top. The introns of petB and petD are marked as IB and ID. Sizes of the transcripts (in nucleotides) referred to in the text and their genic compositions are indicated.
