Phenotype of dlf1 mutant plants. A, A wild-type sib plant (left, red arrow) compared to a dlf1 mutant plant (right, red arrowhead) in the field after flowering of the wild-type plant. Note the dlf1 mutant is taller, with extra leaves, and the tassel has not yet fully extended from the upper whorl of leaves. B, Close-up of a dlf1 tassel with increased branch number and lower branches bearing pistillate flowers enclosed in husk-like leaves (white arrow). Compare to the wild-type tassel in A. C, Close-up of dlf1 with extra ears born at the top ear-bearing node. Wild-type plants bear only single ears at one or two nodes.
