Phenotypic Analysis of Osrdr6-mei.

(A) From left to right: wild-type (WT; top) and Osrdr6-mei (bottom) plants, spikelets with the lemma and palea removed, pollen grains, and embryo sac. ac, antipodal cell; cc, central cell; ec, egg cell. Bars = 500 μm for spikelets; bars = 50 μm for pollen and embryo sacs.

(B) Meiotic chromosome behavior of meiocytes from wild-type (WT) and Osrdr6-mei plants. In Osrdr6-mei meiocytes, arrowheads indicate unpaired chromosomes at pachytene and univalents at diakinesis. Bars = 5 μm.

(C) Transverse section analysis of anthers from the wild type (WT) and Osrdr6-mei. The images are cross sections of a single locule. Bars = 20 μm.
