A Simple Gene-expression System for the Small Subunit of Ribulose Bisphosphate Carboxylase in Leaves OfNicotiana Sylvestris
Overview
Affiliations
InNicotiana sylvestris only four transcripts coding for the small subunit of RUBISCO are present in leaves. They are very closely related as they are identical in the nucleotide sequence of the non-coding regions and show only three silent point differences in the region coding for the mature peptide.The main difference among these four transcripts lies in the length of the non-coding regions. Half of the SmRNA population as confirmed by direct RNA sequencing has an additional nucleotide sequence in the leader region. Two cDNAs have an additional nucleotide sequence at the end of the 3' non-coding region. Based on these criteria the transcripts were classified into two groups:.group I has a 73-nucleotide-long leader sequence and the nucleotides T, A and C at position 327, 432 and 519 in the coding region..group II has a 60-nucleotide-long leader sequence and the nucleotides C, G and T at these positions in the coding region.The two cDNAs showing a difference in the length of the 3' non-coding region belong to group II.The study of all these transcripts argues for the possibility that only two families of genes are expressed in leaves ofN. sylvestris.
