Distal expression of knotted1 in maize leaves leads to reestablishment of proximal/distal patterning and leaf dissection.

Plant physiology - 1 Dec 2009

Ramirez Julio, Bolduc Nathalie, Lisch Damon, Hake Sarah

Abstract excerpt

Maize (Zea mays) leaves provide a useful system to study how proximal/distal patterning is established because of the distinct tissues found in the distal blade and the proximal sheath. Several mutants disrupt this pattern, including the dominant knotted1-like homeobox (knox) mutants. knox genes encode homeodomain proteins of the TALE superclass of transcription factors. Class I knox genes are expressed in the...
