The dotplot is a tool for visualising synteny between the chromosomes of different species.
Plot settings:
You can pick the 'query' and 'subject' species to by selecting them using the relevant dropdown menus below.
Plot navigation:
The plot displays the chromosomes of the query species (x-axis) and the subject species (y-axis). Each box
represents a chromosome-chromosome comparison. Blue dots show ohnologous relationships between chromosomes.
These will be displayed as orange if the query/subject gene is in the current selection (see data download
below). Unbroken diagonal lines are indicative of microsynteny while clouds of dots represent macrosynteny.
Right-clicking on any of the boxes will open a context menu. From here, all the genes in the current box, row,
or column can be added to the current selection. Alternatively, 'free selection' can be enabled producing a
selection box than can be moved and resized. Genes selected this way will also appear as selected in the table
and vice versa. The selection can be cleared by pressing the 'cancel' button above the gene table.
Data download:
Genes that appear in the plot will be displayed in a table below. All gene data can be downloaded by pressing
the 'download' button above the table. Alternatively, inidividual gene data can be downloaded by selecting the
desired rows. This can be done by clicking the checkbox next to each gene name. The selection can be cleared by
pressing the 'cancel' button above the table.
Table navigation:
The 'protein' column provides a link to the relevant pages in our microsynteny and gene tree viewer utilities
respectively. The 'source' column provides a link to the external database from which each gene was sourced.
