Genome Assembly of Gangetic Dolphin (Platanista gangetica) Reveals Signature of Regressive Evolution.

ABSTRACT: The Gangetic dolphin (Platanista gangetica), an endangered freshwater cetacean endemic to the Indian subcontinent, exhibits distinctive morphological and physiological adaptations to riverine habitats. Here, we present a high-quality draft genome assembly of P. gangetica. The assembled genome is 2.53 Gb in size, with a scaffold N50 of 116.1 Mb and a scaffold L50 of 9. Genome completeness assessed using BUSCO against the mammalia_odb10 dataset indicated a genome completeness of 97.73%. We predicted 27,983 protein-coding genes, and 19,616 were confidently mapped to eggNOG ortholog groups. Phylogenetic reconstruction placed the divergence of P. gangetica from the common bottlenose dolphin (Tursiops truncatus) at approximately 30.9 million years ago. Furthermore, we identified 66 positively se
