Green anole (Anolis carolinensis)

Although they are closely related to iguanas, the green anole has the ability to change color like the chameleon. Read more about green anoles on the Wikipedia page.

Draft

The chromosome-length genome assembly is based on the draft assembly AnoCar2.0 (GCA_000090745.2), credited below.

Alföldi, J., Di Palma, F., Grabherr, M., Williams, C., Kong, L., Mauceli, E., Russell, P., Lowe, C.B., Glor, R.E., Jaffe, J.D., Ray, D. A., Boissinot, S., Shedlock, A.M., Botka, C., Castoe, T.A., Colbourne, J.K., Fujita, M.K., Moreno, R.G., ten Hallers, B.F., Haussler, D., … Lindblad-Toh, K., 2011. The genome of the green anole lizard and a comparative analysis with birds and mammals. Nature, 477(7366), 587-591. https://doi.org/10.1038/nature10390.

Method

3D Assembly was performed using 3D-DNA pipeline (Dudchenko et al., Science, 2017). The genome was reviewed using Juicebox Assembly Tools  (Dudchenko et al., bioRxiv, 2018). See Methods for more information.

Hi-C sample

The primary fibroblasts sample for in situ Hi-C preparation was donated by a female individual, and obtained from T.C. Hsu Cryo-Zoo at the University of Texas MD Anderson Cancer Center.

Hi-C Contact maps

Hi-C data was aligned to the draft reference using Juicer (Durand, Shamim et al., Cell Systems, 2016), and contact maps visualizing the alignments with respect to the draft and the new reference were built using 3D-DNA (Dudchenko et al., Science, 2017). The contact maps can be explored below via Juicebox.js interactive tool (Robinson et al., Cell Systems, 2018). To explore the assembly in greater detail, please download the .hic and .assembly files from the data release folder and use Juicebox Assembly Tools  (Dudchenko et al., bioRxiv, 2018).
