Genome size and GC content of myxomycetes.

More than 1272 myxomycetes species have been described, accounting for more than half of all Amoebozoa species. However, the genome size of only three myxomycetes species has been reported. Therefore, we used flow cytometry to present an extensive survey and a phylogeny-based analysis of genome size and GC content evolution in 144 myxomycetes species. The genome size of myxomycetes ranged from 18.7 Mb to 470.3 Mb, and the GC content ranged from 38.7% to 70.1%. Bright-spored clade showed larger genome sizes and more intra-order genome size variations than the dark-spored clade. GC content and genome size were positively correlated in both bright-spored and dark-spored clades, and spore size was positively correlated with genome size and GC content in the bright-spored clade. We provided the first genome size data set in Myxomycetes, and our results will provide helpful information for future Myxomycetes studies, such as genome sequencing. Copyright © 2023 Elsevier GmbH.
