text: Coordinated cell polarization in developing tissues is a recurrent theme in
multicellular organisms. In plants, a directional distribution of the plant hormone
auxin is at the core of many developmental programs. A feedback regulation of
auxin on the polarized localization of PIN auxin transporters in individual cells
has been proposed as a self-organizing mechanism for coordinated tissue polarization,
but the molecular mechanisms linking auxin signalling to PIN-dependent auxin transport
remain unknown. We performed a microarray-based approach to find regulators of
the auxin-induced PIN relocation in the Arabidopsis thaliana root. We identified
a subset of a family of phosphatidylinositol transfer proteins (PITP), the PATELLINs
(PATL). Here, we show that PATLs are expressed in partially overlapping cells
types in different tissues going through mitosis or initiating differentiation
programs. PATLs are plasma membrane-associated proteins accumulated in Arabidopsis
embryos, primary roots, lateral root primordia, and developing stomata. Higher
order patl mutants display reduced PIN1 repolarization in response to auxin, shorter
root apical meristem, and drastic defects in embryo and seedling development.
This suggests PATLs redundantly play a crucial role in polarity and patterning
in Arabidopsis.
