sh1 is a novel allele of hei10. A hei10 (A) and sh1/hei10 biallelic (B) plant after heading. Scale bars = 10 cm. A hei10 (C) and sh1/hei10 biallelic (D) spikelet at maturity. Scale bars = 1 mm. A hei10 (E) and sh1/hei10 biallelic (F) flower after removing the palea and lemma. Scale bars = 1 mm. I2–KI staining of hei10 (G) and sh1/hei10 biallelic (H) mature pollen grains. Scale bars = 0.1 mm. A hei10 (I) and sh1/hei10 biallelic (J) panicle at maturity. Scale bars = 5 cm. Mature plant (K), spikelet (L), flower (M), and I2–KI stained pollen (N) of a HEI10-gDNA;sh1 complementation line. Scale bars = 1 cm (K), 2 mm (L, M) and 0.2 mm (N)
