Description
Gabriele Panicucci and co-authors show that oxygen gradients steer how a young leaf takes shape, in a 2026 paper. Growing tissues are not evenly aired: plant embryos and shoot tips sit in low-oxygen pockets, and a dedicated sensing pathway reads those levels through the stability of key transcription factors. What oxygen does once a leaf starts forming was unknown.
The team found a moving oxygen gradient across the developing leaf, read by that same sensing machinery. Early low oxygen restrained cell expansion. Then a wave of oxygenation, running from tip to base, cleared a set of response factors, unlocking special cell fates and pacing cell division. Oxygen, they conclude, acts as a positional signal in normal growth.
