Comparative Analysis of Transposable Element Evolution in Crustaceans.

ABSTRACT: Transposable elements (TEs) are pivotal in driving genome evolution, playing a significant role in generating genetic diversity, modulating genome size, and inducing chromosome structural changes. Despite extensive research in model species, studies on TE evolution and structure in crustaceans are notably limited. This study offers an in-depth analysis of TEs diversity and its impact on representative crustacean genomes' genome structure and function. Our results revealed substantial variation in TE content among crustacean species, with levels ranging from 16.19% in Daphnia pulex to a high of 63.36% in Procambarus clarkii. Notably, species with larger genomes, such as P. clarkii and Homarus americanus, show a higher proportion of TEs, which implies that TE proliferation may be a major fac
