Cell position is the primary determinant of cell identity in the uniseriate filament of the brown alga Ectocarpus

The brown alga Ectocarpus is a morphologically simple organism, with cells in the growing filament changing shape and position over time.

The brown alga Ectocarpus is a morphologically simple organism, with cells in the growing filament changing shape and position over time. In this study, we investigated the roles of cell shape, position, and age in establishing cell identity in Ectocarpus. Using laser capture…
