Lytechinus variegatus
L. variegatus
- Click on any colour tile in the legend to toggle
visibility of that feature on/off
- The radius of the central plot represents the length of
the longest scaffold in the assembly
- The angle subtended by the first (red) segment within this
plot indicates the percentage of the assembly that is in the
longest scaffold
- The radial axis originates at the circumference and
indicates scaffold length, this is on a square-root scale
- Subsequent (grey) segments are plotted from the
circumference and the length of segment at a given percentage
indicates the cumulative percentage of the assembly that is
contained within scaffolds of at least that length
- The N50 and N90 scaffold lengths are indicated
respectively by dark and light orange arcs that connect to the
radial axis for ease of comparison
- The cumulative number of scaffolds within a given
percentage of the genome is plotted in purple originating at the
centre of the plot
- White scale lines are drawn at successive orders of
magnitude from 10 scaffolds onwards
- The fill colour of the circumferential axis indicates the
percentage base composition of the assembly: AT = light blue; GC =
dark blue; N = grey
- Contig length (off by default) is indicated by darker grey
segments overlaying the scaffold length plot
- Contig count (off by default) may be toggled on to be
shown in place of the scaffold count plot
- Partial and complete BUSCO values are shown in light and
dark green, respectively in the smaller plot in the upper right
corner
About L. variegatus
L. variegatus and
S. purpuratus shared a common ancestor about 50 Million years ago and are ideal models for comparative
genomics studies.
L. variegatus is also a broadcast spawner with external fertilization, exhibits rapid development, and can be cultivated in tanks.
