Sorghum Dw2 Encodes a Protein Kinase Regulator of Stem Internode Length

Abstract Sorghum is an important C4 grass crop grown for grain, forage, sugar, and bioenergy production. While tall, late flowering landraces are commonly grown in Africa, short early flowering varieties were selected in US grain sorghum breeding programs to reduce lodging and to facilitate machine...
