| Outline of Final Research Achievements |
To reveal the establishment and colonisation processes of the bryoflora of the Japanese Archipelago, haplotype variation in the chloroplast genome was studied. Identification of immigrant propagule samples from aerial sources was also attempted based on DNA barcoding. Some key new genetic markers for the chloroplast genome were identified and obtained. Analysis of the results revealed: a greater diversity of potential immigrant taxa than are represented in the established bryoflora; in addition to bryophytes, some ferns and green algal taxa were detected using DNA barcoding. Pseudotaxiphyllum pohliaecarpum, one of the dominant bryophyte species in aerial samples, showed four distinct chloroplast haplotypes in Japanese samples, most likely representing separate historical colonisation events. To effectively monitor the aerobiota and potential advent of additional taxa in the Japanese bryoflora there is an urgent need to enrich and expand the DNA barcoding library for bryophytes.
