Ocean Metagenome from The Andaman Islands
Investigating the microbiome composition in the coastal waters of the Andaman Islands.We investigated the microbiome composition in the coastal waters of the Andaman Islands using 16S rRNA gene amplicon and metagenomic shotgun sequencing approaches. A comparative analysis was done using data from the Tara Oceans Consortium. In the coastal waters, a significantly higher abundance and diversity of Synechococcus species was observed, along with a higher diversity of photosynthesis pigment-related genes to adapt to variable light conditions and nutrition. In contrast, Prochlorococcus species showed higher abundance in open ocean water samples of the Indian Ocean region, with a relatively limited functional diversity. We also updated the ocean microbiome gene catalog.
