Canalization of auxin flow by Aux/IAA-ARF-dependent feed-back regulation of PIN polarity
Original language description
Plant development is characterized by a profound ability to regenerate and form tissues with new axes of polarity. An unsolved question concerns how the position within a tissue and cues from neighbouring cells are integrated to specify the polarity of individual cells. The canalization hypothesis proposes a feed-back effect of the phytohormone auxin on the directionality of intercellular auxin flow as a means to polarize tissues. Here we identify a cellular and molecular mechanism for canalization. Local auxin application, wounding or auxin accumulation during de novo organ formation lead to rearrangements in the subcellular polar localization of PIN auxin transport components. This auxin effect on PIN polarity is cellspecific, does not depend on PINtranscription and involves the Aux/IAA-ARF signalling pathway. Our data suggest that auxin acts as polarizing cue which links individual cell polarity with tissue and organ polarity through control of PIN polar targeting. This feedback re

Kanalizace toku auxinu zpětnovazební regulací polarity PIN závislou na Aux/IAA-ARF
Czech description
Vývoj rostlin je charakterizován schopností regenerovat a vytvářet pletiva s novými osami polarity. Nevyřešenou otázkou zůstávalo, jak poloha buňky v pletivu a signály z okolních buněk jsou integrovány a určují polaritu jednotlivých buněk. Kanalizační hypotéza navrhuje zpětnovazební působení fytohormonu auxinu na usměrňování mezibuněčného toku auxinu jako prostředek pro polarizaci pletiv. V této práci byl identifikován buněčný a molekulární mechanismus kanalizace.
