Extrachromosomal Circular DNA: A Dynamic Regulator of Genome Plasticity and Adaptation in Plants
Extrachromosomal circular DNA (eccDNA) is an emerging class of mobile genetic elements that exist independently of linear chromosomes. Initially recognized for its role in cancer pathogenesis, eccDNA is now gaining traction in plant genomics as a potent driver of genome plasticity. In this Review, we summarize the la...
