Chromochloris

Chromochloris zofingiensis is an emerging model organism for studying triacylglycerol (TAG) and secondary carotenoid (astaxanthin) accumulation, photoprotection, regulation of metabolism, and cell biology of green algae. Chr. zofingiensis (formerly known as Chlorella zofingiensis) exhibits one of the highest levels of TAG accumulation among microalgae and is under development as a model alga, making it a promising feedstock for economically viable and sustainable production of algal biofuels. In collaboration with Matteo Pellegrini and Sabeeha Merchant (UCLA), we have sequenced the nuclear and organelle genomes and transcriptome of Chr. zofingiensis. Data from short Illumina reads, long PacBio reads, and whole-genome restriction fragment length optical mapping were used to generate a high quality, chromosome-level nuclear genome assembly (http://genomes.mcdb.ucla.edu/Chromochloris/index.html). Chr. zofingiensis has a compact ~58 Mbp genome with 19 chromosomes and ~15,000 protein-coding genes (https://phytozome.jgi.doe.gov/pz/portal.html#!info?alias=Org_Czofingiens...).
