Gene model revision and synteny analysis. (A) genBlastG-based C. briggsae gene model revision enables the discovery of larger synteny blocks between C. elegans and C. briggsae. Three small synteny blocks were merged into one single larger synteny block that contains all their adjacent synteny blocks. (B) Four C. briggsae gene models, which were revised or discovered in the genBlastG-based gene model revision, are shown at the synteny block break points. (C) A synteny block between C. elegans and C. briggsae is broken down into two smaller synteny blocks. (D) Two hybrid gene models were merged to form a single gene model based on an RNA-seq Illumina intron. (E) RNA-seq evidence supports the merger of two hybrid C. briggsae gene models into a single gene model. (RS) Number of supporting reads.
