I checked the NCBI FTP site: ftp://ftp.ncbi.nih.gov/genomes/ Here the no. of organisms reported is approximately 389 (for eukaryotes I guess) and there is separate directory for viruses However, this link: https://www.ncbi.nlm.nih.gov/genome/browse/ shows something 7313 for prokaryotes (if I keep only complete genome) and 35 for eukaryotes (keeping complete genome). and 7150 for viruses. So what data should one report as total number of organisms sequenced till date and submitted to NCBI? If anyone can help me with the number and source (with breakage of Eukaryotes,Prokaryotes and Virusesis is even better).
