Outline of Final Research Achievements

Two brown algae Tinocladia crassa and Sphaerotrichia firma were provided from NBRP algae, and were sequenced Illumina MiSeq and NovaSeq. Furthermore, we developed new methods which enabled sequence using Oxford Nanopore Technology minion.
Analyzing the obtained data, we succeeded in assembling the draft genome sequences and collecting the DNA information about likely symbiosis bacteria of those brown algae. Isolation of bacteria from each mozuku species resulted in at least 77 colonies. These are likely to be useful for the development of mozuku species in the future.
