Detection of DNA fragmentation by the TUNEL assay. Green fluorescence indicates TUNEL-positive signals for DNA fragmentation, red fluorescence indicates staining of spikelets and with propidium iodide (PI), and yellow fluorescence results from overlay of green signals of TUNEL and red signals of PI staining. a1–c1: Top spikelets of WT in panicle length at 7 cm. a2–c2 enlargement of region (a1–c1). d1–f1: Top spikelets of paa3 in panicle length at 7 cm. d2–f2 enlargement of region of (d1–f1). g1–i1: Top spikelets of WT in panicle length at 11 cm. g2–i2 enlargement of region (g1–i1). j1–l1 Top spikelets of paa3 in panicle length at 11 cm. j2–l2 enlargement of region of (j1–l1). m1–o1: Top spikelets of WT in panicle length at 15 cm. m2–o2, enlargement of region (m1–o1). p1–r1: Top spikelets of paa3 in panicle length at 15 cm. p2–q2 enlargement of region of (p1–q1). Bars: (a1–r1) 50 μm; (a2–r2) 10 μm. st: stamens; gy: gynoecium; sl: sterile lemma; le: lemma; pa: palea
