The maize transcription factor KNOTTED1 directly regulates the gibberellin catabolism gene ga2ox1.

The Plant cell - 1 Jun 2009

Bolduc Nathalie, Hake Sarah

Abstract excerpt

KNOTTED1 (KN1)-like homeobox (KNOX) transcription factors are involved in the establishment and maintenance of plant meristems; however, few direct targets of KNOX proteins have been recognized. Using a combination of double mutant analysis and biochemistry, we found that in maize (Zea mays), KN1 negatively modulates the accumulation of gibberellin (GA) through the control of ga2ox1, which codes for an enzyme...
