Researchers from Cold Spring Harbor Laboratory (CSHL) and global collaborators identified over 2.3 million conserved non-coding sequences (CNSs) across 314 plant genomes from 284 species, using a new computational tool called Conservatory. These ancient 'DNA switches' originated before flowering plants diverged from non-flowering ancestors more than 400 million years ago, with some confirmed essential for developmental functions through genetic editing. The discovery provides a comprehensive atlas for plant biology, aiding crop breeders in addressing drought and food shortages by fine-tuning traits. CSHL's Zachary Lippman described it as 'a new window into the evolution of life across eons.'
