Fig. 8. ifa1 ids1 double mutant phenotype. Individuals are from a family segregating for the ifa1 ids1 double mutant phenotype. (A) ids1-mum1 ear. (B) ifa1-r ear. (C-F) ifa1-r ids1-mum1 ear. Each spikelet forms an ectopic inflorescence. (E) ifa1-r ids1-mum1 spikelet pair. Both spikelets in a pair are affected. (F) ifa1-r ids1-mum1 spikelet with three florets and an ectopic inflorescence. The ectopic inflorescence forms spikelet pairs along its axis (arrow points to a spikelet pair). (G-I) ifa1-r ids1-mum1 tassel. (H) Spikelet pair of an ifa1-r ids1-mum1 plant. Many more spikelets form than in normal plants. (I) A series of spikelets form inside the glumes of the spikelet. sp, spikelet; sp*, extra spikelet; f, floret; g, glume; sm*, ectopic inflorescence that arises from an SM.
