Phylogenetic diversity and functional potential of large and cell-associated viruses in the Bay of Bengal
ABSTRACTThe Bay of Bengal (BoB) is the world’s largest bay, offering essential services like fishing and recreation while holding significant economic value for coastal communities. However, the BoB faces environmental challenges from monsoons, freshwater inputs, rising sea levels, and intensified c...
