Round goby Neogobius melanostomus genome annotation

Annotation file for the round goby genome (sequence deposited as “RGoby_Basel_V2”, BioProject accession PRJNA549924, BioSample SAMN12099445, GenBank genome accession VHKM00000000, release date July 22 2019).  Supplementary Material S1 for Adrian-Kalchhauser et al, BMC Biology, The round goby genome provides insights into mechanisms that may facilitate biological invasions. The round goby genome assembly was annotated using Maker v2.31.8. Two iterations were run with assembled transcripts from round goby embryonic tissue and data from eleven other actinopterygian species available in the ENSEMBL database as well as the SwissProt protein set from the uniprot database as evidence (downloaded March 2, 2016). In addition, an initial set of reference sequences obtained from a closely related species, the sand goby (Pomatoschistus minutus), sequenced by the IMAGO marine genomes project of the CeMEB consortium at University of Gothenburg, Sweden was included. The second maker iteration was run after first training the gene modeler SNAP version 2006-07-28 based on the results from the first run. Augustus v3.2.2 was run with initial parameter settings from zebrafish (Danio rerio). Repeat regions in the genome were masked using RepeatMasker known elements and repeat libraries from Repbase as well as de novo identified repeats from the round goby genome assembly obtained from a RepeatModeler analysis.

Fig. 2 in The marbled goby, Pomatoschistus marmoratus, as a promising species for experimental evolution studies

Fig. 2 Total length (a) and survival probability (b) of the marbled goby larvae at successive dph. White bars represent a family selected for the blue spot on the male dorsal fin and reared at 18 °C; black bars represent a family selected for body size and reared at 18 °C; grey bars represent a family selected for body size and reared in captivity at 24 °C. The warmer line (24 °C) was lost between 130 and 160 dph. Each family has offspring from the same mother and two different fathers (double bars). Since survival and size remained almost constant after 160 dph successive measures between 160 and 360 dph are omitted and only the final values at 360 dph are reported. Error bars in a represent the standard error of the mean

Fig. 4 in Species and shape diversification are inversely correlated among gobies and cardinalfishes (Teleostei: Gobiiformes)

Fig. 4 Phylomorphospace for Gobiiformes. The phylogeny is superimposed on a plot of PC1 vs. PC2, with points color coded as indicated on the figure. Pseudamia is labeled to distinguish it from the other Apogonidae because the phylogeny indicates that it forms a lineage

FIG. 10 in Organization and Ontogeny of a Complex Lateral Line System in a Goby (Elacatinus lori), with a Consideration of Function and Ecology

FIG. 10. Ontogeny of neuromast distribution in E. lori derived from fluorescent images. (A) 0 dph, 3 mm TL; (B) 10 dph, 4.5 mm SL; (C) 20 dph, 6.5 mm SL; (D) 31 dph, 9 mm SL; and (E) 38 dph, 9 mm SL presettlement larva. Pectoral fin removed to facilitate visualization of all neuromasts on the trunk. Yolk sac not drawn. Scale bar ¼ 1 mm. See Figures 3 and 4 for identity of neuromasts.

FIG. 2 in Organization and Ontogeny of a Complex Lateral Line System in a Goby (Elacatinus lori), with a Consideration of Function and Ecology

FIG. 2. Neuromast distributions in E. lori vitally stained with 4-di-2-ASP (lateral view, rostral to the left). (A) 0 dph (3 mm NL; yolk sac larva, fin folds still present) with only nine neuromasts present on head. By 1 dph, the yolk sac is fully absorbed and by 10 dph, flexion has started. (B) 38 dph (9.5 mm SL, pre-settlement) individual with all neuromast lines present on head; only the neuromasts in lines on operculum and mandible have begun to proliferate. Canal neuromasts are still visible (e.g., dorsal to orbit), indicating that the canals are not yet fully ossified. Settlement occurs at ~30–45 dph, 9–11 mm SL. (C) Wild-caught adult (42 mm SL) with lines of proliferated superficial neuromasts on head. (D) Trunk and tail of 20 dph (6 mm SL) larva. The few neuromasts on trunk will proliferate to become short vertical series of superficial neuromasts (see F). A few neuromasts on the caudal fin occur in three lines. (E) Anterior portion of the trunk (adult, 42 mm SL) illustrating several short lines of neuromasts. (F) Posterior portion of the trunk (adult, 42 mm SL) with well-organized vertical lines of neuromasts (''stitches'') on each myomere along horizontal septum. (G) Caudal fin (adult, 42 mm SL) with three lines (lines lc, lc1, and lc2) of densely placed neuromasts extending from the fin base to the tip of the caudal fin on the membranes between fin rays. Caudal-fin membranes are so thin that the neuromasts from both the left (white arrowhead) and right (yellow arrowhead) side are visible within a line. See Figures 3 and 4 for identification of neuromast lines.

FIG. 6 in Organization and Ontogeny of a Complex Lateral Line System in a Goby (Elacatinus lori), with a Consideration of Function and Ecology

FIG. 6. Neuromast and cupular morphology in E. lori. (A) Neuromast showing hair cells in central sensory strip with opposing polarities (hair cell orientation; double-headed arrow). (B) Detail of neuromast, as in A, showing ciliary bundles of individual hair cells (each with kinocilium [kc] and multiple stereocilia [sc]) with opposing polarities. (C) Gelatinous cupula (cu) retained on a neuromast that has the same orientation as neuromast in A; note the ''wing-like'' extensions of the cupula that reaches to the tips (arrows) of the elongate neuromast. (D) Neuromast that appears to be in the process of budding, which is thought to be the mechanism for neuromast proliferation. Double-headed arrows ¼ hair cell orientation.

FIG. 5 in Organization and Ontogeny of a Complex Lateral Line System in a Goby (Elacatinus lori), with a Consideration of Function and Ecology

FIG. 5. Lateral line development in E. lori. (A–E) Supraorbital (SO) canal with canal neuromasts (CNs) between orbits and superficial neuromasts in larvae. (A) CN (arrow) prior to canal enclosure (Stage I) at 0 dph. (B) CN (arrow) in depression as canal formation starts (Stage IIa) at 10 dph (5 mm SL). Nuclei of cells in two layers are visible in the neuromast (upper layer, sensory hair cells; lower layer, non-sensory support cells). (C) Left and right CNs (arrows) in the SO canal in the dorsal midline, with canal walls rising (*, Stage IIb), but not yet enclosing the CNs. (D) Left and right CNs (arrows, as in C; cupula of left neuromast is visible) are enclosed in the ossified SO canal (Stage IV; wild-caught settler, 14 mm SL). (E) Example of a line of densely placed superficial neuromasts (line c2) in wild-caught settler (14 mm SL) in the nasal area; prominent olfactory epithelium (oe). Stages of canal development (I–IV) follow Webb and Shirey (2003). (F–J) Ontogeny of superficial neuromast size and shape in E. lori showing diamond shape and gradual restriction of hair cells to a central, oval sensory strip. Axis of best physiological sensitivity (hair cell orientation) is perpendicular to the long axis of the neuromast. (F) 0 dph—neuromast on trunk is already diamond-shaped, (G) 10 dph—neuromast on trunk, (H) 20 dph—neuromast on cheek, (I) 34 dph—neuromast on cheek, note that sensory strip takes up a smaller portion of area of the neuromast compared to those in F–H. (J) Adult—superficial neuromast on caudal fin. Scale bars: A–E, 50 lm; F–H, 2 lm; I–J, 5 lm.

FIG. 9 in Organization and Ontogeny of a Complex Lateral Line System in a Goby (Elacatinus lori), with a Consideration of Function and Ecology

FIG. 9. Comparison of neuromast size in post-settlement juveniles and adult E. lori. Least squared means of (A) neuromast length and (B) neuromast width and standard error are plotted for each neuromast type (canal neuromasts [CN], canal neuromast homologs [CNH], superficial neuromasts [SN])—Head CN (n ¼ 13), Head CNH (n ¼ 45), Head SN (n ¼ 102), Trunk SN (n ¼ 65), and Tail SN (n ¼ 8)—based on linear measurements of scanning electron micrographs. Statistically significant differences are indicated by brackets (post hoc Tukey's HSD, P, 0.05).
