Phenotype of pap2-1 in spikelet development. (A–C) Spikelets in the wild-type (A) and pap2-1 (B, C). Rudimentary glumes (red arrowheads) and sterile lemmas (yellow arrowheads) elongate in pap2-1. An ectopic organ (blue arrowhead) often developed in the axil of the rudimentary glume in pap2-1 (B, C). Scale bars = 1 mm. (D–F) SEM analysis of the spikelet of wild-type (D) and pap2-1 (E, F). Scale bars = 500 μm. (G and H) Number of rudimentary glumes (G) and sterile lemmas (H) in the wild-type and pap2-1. Sample size, n = 40. (I and J) Surface of sterile lemmas in the wild-type (I) and pap2-1 (J). Scale bars = 100 μm. (K and L) Floral organs in the wild-type (K) and pap2-1 (L) spikelets. (M) Schematics of spikelets from the wild-type (left) and pap2-1 (right). rg, rudimentary glume; sl, sterile lemma; fi, filamentous organ; le, lemma; fl, floret.
