Seed production requires the transfer of nutrients from the maternal seed coat to the filial endosperm and embryo. Because seed coat and filial tissues are symplasmically isolated, nutrients arriving in the seed coat via the phloem must be exported to the apoplast before reaching the embryo. Proteins implicated in the transfer of inorganic phosphate (Pi) from the seed coat to the embryo are unknown despite seed P content being an important agronomic trait.

The study by Bi and colleagues [5] adds to the emerging picture drawn for eukaryotic cells in which the nuclear periphery offers a functional compartment for genome regulation, unveiling antagonistic chromatin contexts in Arabidopsis.
