CC   -!- FUNCTION: Required for normal spindle orientation at male meiosis II
CC       and normal formation of tetrad of microspores. Not involved in female
CC       meiosis. {ECO:0000269|PubMed:19043546}.
CC   -!- DISRUPTION PHENOTYPE: Diploid pollen grains (dyads of spores instead of
CC       tetrads) due to defective meiosis II. Abnormal spindle orientation at
CC       meiosis II. {ECO:0000269|PubMed:19043546}.
CC   -!- MISCELLANEOUS: Diploid male spores in sp1 mutants give rise to viable
CC       diploid pollen grains and spontaneous triploid plants in the next
CC       generation. {ECO:0000269|PubMed:19043546}.
