A gain-of-function mutation in IAA18 alters Arabidopsis embryonic apical patterning.

Development (Cambridge, England) - 1 May 2009

Ploense Sara E, Wu Miin-Feng, Nagpal Punita, Reed Jason W

Abstract excerpt

Lateral organ emergence in plant embryos and meristems depends on spatially coordinated auxin transport and auxin response. Here, we report the gain-of-function iaa18-1 mutation in Arabidopsis, which stabilizes the Aux/IAA protein IAA18 and causes aberrant cotyledon placement in embryos. IAA18 was expressed in the apical domain of globular stage embryos, and in the shoot apical meristem and adaxial domain of...
