Coleorhiza‐enforced seed dormancy: a novel mechanism to control germination in grasses

What is it about?

'Knowing when to grow' depends on plant tissue interactions with hormonal signals and biochemical cell wall remodeling to weaken or stiffen mechanical tissues. The coleorhiza, a sheath-like organ that surrounds the root in grass seed embryos, confers dormancy and controls germination through modulation of its cell wall mechanical properties.
