Characteristics of abortion spikelets. a: Representative images of WT (left) and paa3 (right) developing panicles, showing different stages as indicated by panicle length:1 cm (a1), 3 cm (a2), 5 cm (a3), 7 cm (a4), 9 cm (a5), 11 cm (a6), 13 cm (a7), 15 cm (a8) and 17 cm(a9). b: The apical developing panicles, showing different stages as indicated by panicle length: 9 cm (b1, b2),11 cm (b3, b4),13 cm (b5, b6),15 cm (b7, b8),17 cm (b9, b10). c: Top spikelet in paa3 mutants and WT; Total spikelet(c1), Spikelet without lemma(c2). (panicle length = 11 cm): d: Scanning electron microscopy observation of top spikelet in paa3 mutant and WT: total spikelet of WT(d1), total spikelet of paa3(d2), WT lemma (d3), paa3 lemma (d4), WT palea (d5). paa3 palea (d6). e: Analysis of the aborted panicle in paa3: The image of the primary branch of paa3 panicle; Arabic numerals (1–9) denote the serial number of PBs(e1), Analysis of degenerated spikelets in each primary branch of paa3 in e1(e2). Bars: (a1–a9, e1)1cm; (b1–b10 and c1–c2)5mm; (d1–d2) 2 mm; (d3–d4) 120 μm
