8.1 A. Spikes of Compositum 1 (com1.a) mutant to the left compared to cultivar Bowman. B. A single com1.a spike that has been bent to better visualize the branches of a few small spikes from the rachis at the lower part of the spike. Several thread-like awns are protruding from the cluster of small spikelets. 8.2 Mutant Opposite spikelets 1 (ops1.3) to the left in each photo, displays variable lengths of rachis internodes, which causes an irregular arrangement of spikelets in the spike. A. Spike of ops1.3 compared to Bowman. B. Spikelets have been removed in order to view the rachis nodes and internodes. 8.3 Lateral spikelets at the base of the spike fail to develop or are partially developed in Absent lower laterals 1 (als1.a) mutants (left) compared to Bowman (right)
