Alignment of group-specific primer set regions

Sequence alignment of DNA regions targeted by the four group-specific primer pairs amplifying Bird, Invertebrate and Plant (mitochondrial and chloroplastic) DNA. Target and non target species were aligned for each group-specific primer pair. Target species were chosen to be as much as possible divergent in order to highlight the potentiality of each primer pair to amplify a wide prey diversity. "N" represents unavailable nucleotide in the existing Genbank sequence, "-" indicates gap and nucleotides between brackets indicate insertions. Note that because Animals do not have chloraplastic DNA, only sequences from target species were aligned for the Plant chloroplastic primer pair.
