Plant Meristems: A Layered Defense Against Mutations
New research reveals that mutation rates within a plant's stem cells vary significantly by layer, with germline-progenitor cells experiencing lower rates than surface cells. This suggests plants actively protect their germline and optimize mutation accumulation based on cellular context, balancing genetic stability with adaptability.
