trans-splicing of transcripts for the chloroplast psaA1 gene. In vivo requirement for nuclear gene products
Journal of Biological Chemistry
Photosystem I-deficient Chlamydomonas reinhardtii mutants M18 and F27 lack mature mRNA for the psaA1 gene of photosystem I but accumulate unspliced and partially spliced psaA1 transcripts. Analysis of these transcripts indicate that 1) exon 1 of psaA1 is transcribed separately from exon 2, 2) exon 2 is cotranscribed with the psbD gene, and 3) at least two nuclear gene products are required for exon 1-exon 2 trans-splicing. In addition, analysis of chloroplast transcription in permeabilizedpmid:3049581 fatcat:plabvjhvavcbrit47nfmyw3gxq
