Distribution of
origin-unknown tRNACys(GCA) gene in plant
mitochondria
We have identified novel tRNACys(GCA) gene whose origin is neither native
(i.e. originated from proto-mitochondria) nor plastid
(some plant mitochondrial tRNA genes are plastid origin) (Kitazaki
et al. 2011). As nucleotide sequences of plant mitochondrial DNA have mounted, additional
instances of plant species having this tRNACys(GCA)
are found. Below we summarize the presence of this tRNACys(GCA)
sequence based on the results of BLASTN search.
