Chloroplast DNA sequence of the green alga Oedogonium cardiacum (Chlorophyceae): Unique genome architecture, derived characters shared with the Chaetophorales and novel genes acquired through horizontal transfer

Table 4 Introns in Oedogonium cpDNA

^a Insertion sites of introns in genes coding for tRNAs and proteins are given relative to the corresponding genes in Mesostigma cpDNA; insertion sites in rrs and rrl are given relative to E. coli 16S and 23S rRNAs, respectively. For each insertion site, the position corresponding to the nucleotide immediately preceding the intron is reported.
^b Group I introns were classified according to Michel and Westhof [38], whereas classification of group II introns was according to Michel et al. [39].
^c L followed by a number refers to the loop extending the base-paired region identified by the number; D refers to a domain of group II intron secondary structure.
^d For the group I intron ORFs, the conserved motif in the predicted endonuclease is given, with the number of copies of the LAGLIDADG motif indicated in parentheses. For the psbI intron ORF, RT and X refer to the reverse transcriptase and maturase domains of group II intron-encoded proteins.
