T2T genome assemblies of Chlorella sorokiniana NS4-2 and Chlorella pyrenoidosa DBH. A Micrograph of C. sorokiniana NS4-2, with bar length = 20 μm; (B) Karyotype diagram indicating that C. sorokiniana NS4-2 has 12 chromosomes; (C) Hi-C contact map of the C. sorokiniana NS4-2 T2T assembly; (D) Circular plot showing the principal genomic features of both the C. sorokiniana NS4-2 and C. pyrenoidosa DBH assemblies: karyotype distribution (track a); GC density (track b); gene density (track c); LINE element density (track d); LTR element density (track e); putative centromeric loci (track f). Densities were calculated in 50 Kb windows. The innermost of the circular plots represents the synteny relationship between C. sorokiniana NS4-2 and C. pyrenoidosa DBH
