Cell polarity and PIN protein positioning in Arabidopsis require STEROL METHYLTRANSFERASE1 function.

The Plant cell - 1 Mar 2003

Willemsen Viola, Friml Jirí, Grebe Markus, van den Toorn Albert, Palme Klaus, Scheres Ben

Abstract excerpt

Plants have many polarized cell types, but relatively little is known about the mechanisms that establish polarity. The orc mutant was identified originally by defects in root patterning, and positional cloning revealed that the affected gene encodes STEROL METHYLTRANSFERASE1, which is required for the appropriate synthesis and composition of major membrane sterols. smt1(orc) mutants displayed several conspicuous...
