Division Tracheophyta (Vascular Plants) 3. <> These five chondromes plus the two from the hornworts Phaeoceros laevis and Megaceros aenigmaticus for the first time allowed comprehensive comparative analyses of structure and organization of mitochondrial genomes both within and across the three major lineages of bryophytes. When they unite, the resulting cell is diploid and the ensuing embryo continues its development as a diploid individual. In bryophytes, the mitochondrial genomes of two liverworts, one moss and two hornworts have been completely sequenced, and their size range varies roughly by two times (Table 7.1).The smallest chondrome sequenced so far (105,340 base pairs (bp)) is found in the moss Physcomitrella patens (Terasawa et al.
