Texas Rat snake genome
We assembled linked reads of 10x Genomics sequencing to obtain a high-quality genome for the Texas Rat snake (Pantherophis obsoletus lindheimeri). The assembly is accessible on NCBI. You can access our own Texas Rat snake annotation via our JBrowse.
The high continuity of this genome (see statistics in the table below), coupled with extensive annotation, already helped us to identify a candidate variant for different Texas Rat snake color morphs and compare them with the variants identified in the corn snake color morphs.
One example is our recently-published study in which we suggest that differential expression of MITF might be responsible for the Leucistic Texas Rat snake phenotype.
