Evidence that the Arabidopsis nuclear gibberellin signalling protein GAI is not destabilised by gibberellin.

The Plant journal : for cell and molecular biology - 1 Dec 2002

Fleck Barbara, Harberd Nicholas P

Abstract excerpt

Plant growth is regulated by bioactive gibberellin (GA), although there is an unexplained diversity in the magnitude of the GA responses exhibited by different plant species. GA acts via a group of orthologous proteins known as the DELLA proteins. The Arabidopsis genome contains genes encoding five different DELLA proteins, the best known of which are GAI and RGA. The DELLA proteins are thought to act as...
