Characterization of a barley ( L.) mutant with multiple stem nodes and spikes and dwarf () and fine-mapping of its causal gene.

Introduction: Multiple nodes and dwarf mutants in barley are a valuable resource for identifying genes that control shoot branching, vegetative growth and development.

Methods: In this study, physiological, microscopic and genetic analysis were conducted to characterize and fine-map the underling gene of a barley mutant with Multiple Stem Nodes and Spikes and Dwarf (), which was selected from EMS- and Co-treated barley . Edamai 934.
