P.9 2nd paragraph: "Prasinovirus genomes are smaller than most other phycodnavirus genomes, ranging from 184 to 198 kbp (Table 1), compared, for example, to the coccolithoviruses, which can be as large as 415 kbp [refs 12, 76, 77]. The smaller sizes of prasinovirus genomes can be attributed not only to fewer coding DNA sequences (CDSs) but also to a general trend towards smaller CDSs and intergenic regions. For example OtV-2 [ref 33] contains a similar CDS number to the phycodnavirus Heterosigma akashiwo virus, HaV-53 [ref 78], (237 versus 246 CDSs), but has a 110 kbp smaller genome (Table 1). The GC content of prasinovirus genomes is lower than that of their host genomes—37%–45% GC [refs 31, 33] compared to 50%–64% GC [refs 27, 28, 29], respectively (Table 1)." See note beneath table |
