Extended Data Fig. 3: Synteny evolution in Gnathifera.
From: The genomic origin of the unique chaetognath body plan
‘Oxford’ synteny plots showing the pairwise synteny relationship between the chaetognath P. gotoi, the sea star Asterias rubens (a), the sea scallop Pecten maximus (b), the amphioxus Branchiostoma Floridae (c), the rotifer Adineta vaga (d). A direct comparison between rotifers (e, Adineta saga; f, Brachionus manjacavas) and sea scallop highlights the lack of direct correspondence and the loss of ALGs in rotifers. Orthologuous genes are computed as mutual-best-hits (MBH) and coloured according to the inferred ALGs. Dots in pairs of chromosomes that show a reciprocal enrichment using Fisher’s exact test (p < 0.05, one-sided) are coloured according to their ALG assignments (a,b,d) or arbitrarily (c).
