De novo assembly and annotation of Tetradesmus sp. strain 198, a green algal from dryland soil | Microbiology Resource Announcements Tetradesmus sp. strain 198, a newly described strain of the Chlorophyceae class within the Scenedesmaceae family, has been identified as belonging to the Tetradesmus bajacalifornicus clade based on reference 1. It was isolated from a bare soil sample in an arid region of Australia’s east coast (34.71686, 144.77065), during the Biodesert global dryland survey (2). The strain was cultivated in an Erlenmeyer flask containing 50 mL of modified Bold Basal Medium (3) under continuous light at 22°C and 100 photons m−2 s−1 for 2 weeks. DNA extraction was performed using the NucleoSpin Plant II kit (Macherey-Nagel, Düren, Germany) according to the manufacturer’s instructions. Two sequencing libraries were prepared: a Nanopore long-read library, sequenced on the ONT MinION system (15 Gbp of raw reads) and an Illumina short-read library, sequenced on the NovaSeqX Plus platform (6.75 Gbp of raw paired-end reads). https://journals.asm.org/doi/full/10.1128/mra.01015-24
