Elucidating the evolutionary dynamics of parasitism in Cuscuta: in-depth phylogenetic reconstruction and extensive plastomes reduction

The study of Cuscuta plastomes reveals the profound impact of parasitism on genome evolution, highlighting the complex interplay of gene retention and loss through phylogenomic approaches. This research enriches our understanding of plant genome evolution and the intricate host-parasite relationships. It also sheds light on the evolutionary history and genomic adaptations of Cuscuta, illustrating the diverse strategies enabling subg. Grammica, Pachystigma, Cuscuta, and Monogynella thrive as parasitic species. These findings provide valuable insights into the molecular mechanisms underlying parasitism and its impact on plastid genome organization.
