Chromosome-level Atlantic switchgrass assemblies reveal a supernumerary B-Chromosome with transcriptional and evolutionary impacts

Supernumerary B-Chromosomes are extra genetic elements that frequently deviate from Mendelian inheritance to ensure their own survival. Their evolutionary origins and biological impacts within natural plant populations remain largely unexplored. Switchgrass (Panicum virgatum) is a model for studies of local adaptation,...

A VIM2/4 deletion, and premature truncations of CMT2 and FBX5, drive DNA methylation changes after colonization of a novel habitat

This study shows that Arabidopsis thaliana colonizing the Cape Verde Islands rapidly evolved altered DNA methylation patterns through high-impact mutations affecting VIM2/4, CMT2 and FBX5, linked to alternative drought adaptation strategies.
