Abstract excerpt
Land plants secrete a protective outer cuticular layer with diverse functions. Barley (Hordeum vulgare L.) develops two cuticular specialisations: the β-diketone rich wax bloom on vegetative tissues and an adherent grain surface which sticks to the hulls, leading to barley's distinctive 'covered' grain phenotype. Two barley SHINE transcription factors, HvWIN1 and NUD, promote the wax bloom and covered grain...
