Location is everything for plant cell differentiation

During development, plant cell differentiation is guided by location rather than lineage. Now, researchers from Osaka University have shown that the accumulation and intracellular localization of regulatory protein ATML1, which controls the expression of genes associated with epidermal cell identity, are also critical for the differentiation of plant cells into an epidermal layer.
