Comparative genomics and evolutionary analyses of Sphaeropleales.

ABSTRACT: Sphaeropleales is a diverse group with over one thousand species described, which are found in a wide range of habitats showed strong environmental adaptability. This study presented comprehensive genomic analyses of seven newly sequenced Sphaeropleales strains with BUSCO completeness exceeding 90%, alongside comparative assessments with previously sequenced genomes. The genome sizes of Sphaeropleales species ranged from 39.8 Mb to 151.9 Mb, with most having a GC content around 56%. Orthologous analysis revealed unique gene families in each strain, comprising 2 to 3.5% of all genes. Comparative functional analysis indicated that transporters, genes encoding pyrroline-5-carboxylate reductase and antioxidant enzymes played a crucial role in adaptation to environmental stressors like salinity
