Genome of South African dwarf chameleons decoded
After a reference genome for the panther chameleon (Furcifer pardalis) was recently published for the first time in China, scientists from South Africa have now followed with the genome of two dwarf chameleon species.
For the analyses, a male Bradypodion pumilum from Cape Town and a male Bradypodion ventrale from an introduced population in Johannesburg were taken. Muscle and liver tissue was used for long sequencing (HiC). The genome size of Bradypodion pumilum is 2.43 gigabase pairs (Gb), that of Bradypodion ventrale 2.40 Gb. The BUSCO analysis demonstrated a high completeness with about 97% of all existing coding genes in vertebrates. Furthermore, the current publication confirms the six macrochromosomes already found from the karyotype in Bradypodion thamnobates 2017. Various comparisons with Anolis sagrei were made. It remains open which chromosomes in Bradypodion are sex chromosomes.
The genomes can be viewed in the NCBI BioProject under the number PRJNA9861319 and under the BioSample numbers SAMN35825189 and SAMN35825190 respectively.
