title: Plant development: small RNAs and the metamorphosis of leaves.
abstract: In many plant species, the degree of serration and complexity in successive leaves increases. A new study suggests that small-RNA-mediated licensing of competitive interactions between transcription factors links the developmental clock regulating vegetative phase change with leaf morphology.
