  1. 1The C in the first anticodon position of trnI(cau) is assumed to be post-transcriptionally converted to lysidine, which pairs with A.
  2. 2trnfM(cau) transfers formylmethionine and therefore is assumed to recognize only the AUG start codon. The genome also contains a gene with homology to the chloroplast trnM gene (which recognizes internal AUG codons), but it has experienced a large expansion in its anticodon loop, making its functionality (and its anticodon) uncertain (Additional File 2).
  3. 3The genome contains a native trnP(ugg) gene as well as a homolog of the chloroplast trnP(ugg) gene. The chloroplast-derived copy is likely a pseudogene in S. latifolia, as it is believed to be in some other angiosperm mitochondrial genomes [90, 93]. Its anticodon loop has experienced multiple substitutions, including one that converts the ancestral UGG anticodon to AGG (Additional File 2).
