Length1 means the length of nucleotide sequence determined by primer walking. Length2 is the length excluding the uncertain regions after a multiple alignment using MAFFT and TrimAl with a “gappyout” option
^aThe sequence that includes a gap of unknown length (see also DDBJ database: Accession number LC121029)
