Ortholog hit ratio of transcripts with ORF comparing to zebrafish protein database.

(A) ortholog hit ratio against target protein length, showing the relationship of the completeness of transcripts with lengths. (B) Ortholog hit ratio distribution for all transcripts with ORF. A ratio of 1 means the transcript thoroughly covers the target in zebrafish protein database, and a value larger than 1 implies a possible gene extension.

(A) 针对目标蛋白长度的直系同源匹配率（ortholog hit ratio），用于展示转录本完整性与其长度之间的相关性。(B) 所有携带开放阅读框（Open Reading Frame, ORF）的转录本的直系同源匹配率分布情况：当匹配率为1时，代表该转录本可在斑马鱼蛋白数据库中完全覆盖目标蛋白；若匹配率大于1，则暗示该转录本存在基因延伸的可能性。
