Genome of the wild crucian carp from Norway. (a) Wild crucian carp specimen collected in Tjernsrudtjernet pond (Oslo), by our research group during autumn. (b) Genomescope k-mer spectra that shows the fingerprint of a diploid without contamination. (c) Snail-plot visualization of the crucian carp assembly metrics. (d) Visualisation of chromatin contact points after mapping of Hi-C reads. After Juicebox curation, 50 scaffolds that were significantly larger than remaining scaffolds emerged, corresponding to the 50 chromosomes. (e) Collinearity analysis of the 50 scaffolds and synteny plotting reveals a pairing of the 50 scaffolds into two sub-genomes, which is expected in the crucian carp genome (collinearity blocks filtered with E value 1e-10 and minimum 7 genes). Note that in this figure, chromosomes named ccar-ua1 to ccar-ua25 in the assembly and annotation files are referred to as wc1 to wc25, while ccar-ub1 to ccar-ub25 are referred to as wc26-wc50 (due to requirements of MCScanX and Synvisio that were used for plotting).
