The complete mitogenome of the Antarctic moss Bartramia patens Brid

Abstract

The complete mitogenome (106,827bp) of the Antarctic moss Bartramia patens Brid. (Bartramiaceae) was analyzed. It consists of 40 proteincoding genes, three ribosomal RNAs and 24 transfer RNAs. The phylogenetic tree based on the combined amino acids sequences of 32 mitochondrial genes showed B. patens to have a sister relationship with B. pomiformis. The size of the mitochondrial genome of B. patens was 629 bp larger than that of B. pomiformis due to the expansion of the intronic region. This phenomenon is very characteristic and requires more comparative studies with the mitogenomes of other bryophytes.
