A transcriptomic hourglass in brown algae.

ABSTRACT: Complex multicellularity has emerged independently across a few eukaryotic lineages and is often associated with the rise of elaborate, tightly coordinated developmental processes^1,2. How multicellularity and development are interconnected in evolution is a major question in biology. The hourglass model of embryonic evolution depicts how developmental processes are conserved during evolution, and predicts morphological and molecular divergence in early and late embryogenesis, bridged by a conserved mid-embryonic (phylotypic) period linked to the formation of the basic body plan^3,4. Initially found in animal embryos^5-8, molecular hourglass patterns have recently been proposed for land plants and fungi^9,10. However, whether the hourglass pattern is
