Plant polarity articles from across Nature Portfolio

Plant polarity refers to the asymmetric distribution of cellular components along a particular axis within a cell, and is essential for processes such as intercellular communication, cell division, cell morphogenesis and differentiation. Polarised cells are involved in the patterning of plant tissues and organs, and therefore contribute to the overall shape of the plant.

    Pollen apertures are the manifestation of distinct plasma membrane domains on the pollen surface. A new study discovered two proteins in rice that are localized specifically to the aperture domains in the membrane of developing pollen and are involved in aperture formation.

    Roots must sort the good from the bad and distinguish the inside from the outside. In endodermal cells, a ring-like apoplastic diffusion barrier called the Casparian strip is established, splitting the cells down the middle into inner and outer lateral halves. Its integrity and polarity depends on a novel protein kinase called SCHENGEN1.
