Unequal redundancy in maize knotted1 homeobox genes.

Abstract excerpt

The knotted1 (kn1) homeobox (knox) gene family was first identified through gain-of-function dominant mutants in maize (Zea mays). Class I knox members are expressed in meristems but excluded from leaves. In maize, a loss-of-function phenotype has only been characterized for kn1. To assess the function of another knox member, we characterized a loss-of-function mutation of rough sheath1 (rs1). rs1-mum1 has no...
