Abstract

ORIG CZ

V originále

The directional transport of the plant hormone auxin is a unique process mediating a wide variety of developmental processes. Auxin movement between cells depends on AUX1/LAX, PGP and PIN protein families that mediate auxin transport across the plasma membrane. The directionality of auxin flow within tissues is largely determined by polar, subcellular localization of PIN auxin efflux carriers. PIN proteins undergo rapid subcellular dynamics that is important for the process of auxin transport and its directionality. Furthermore, various environmental and endogenous signals can modulate trafficking and polarity of PIN proteins and by this mechanism change auxin distribution. Thus, the subcellular dynamics of auxin transport proteins represents an important interface between cellular processes and development of the whole plant. This review summarizes our recent contributions to the field of PIN trafficking and auxin transport regulation.

In Czech

Transport rostliného hormonu auxinu reguluje různé vývojové procesy. Auxinový transport závisí na AUX1/LAX, PGP and PIN proteinech, které pumpují auxin přes buněčnou membránu. Polarita auxinového toku závisí na polární buněčné lokalizaci PIN transporterů, které vykazují permanentní vnitrobuněčnou dynamiku. Toto review sumarizuje nejnovější příspěvky a poznatky k této problematice.
