Ectopic expression of the knox homeo box gene rough sheath1 alters cell fate in the maize leaf.

Abstract excerpt

Rough sheath1 (Rs1) is a dominant mutation that alters cell fate and causes unregulated cell division and expansion in the maize leaf. A knox (Kn1 like-homeo box gene) sequence closely linked to the Rs1-O mutation was cloned and shown by transposon mutagenesis to encode the rs1 gene. The deduced amino acid sequence of the RS1 protein is highly similar to KN1 in the homeo domain but contains a unique...
