Phenotype
gem1 affects post-meiotic cytokinesis of the microspore at pollen mitosis I, causing altered cell division asymmetry and cell fate. Equal daughter cells resulting from symmetric division at pollen mitosis I both show vegetative cell fate. This produces mature pollen with two 'vegetative' cells and no generative or sperm cells. About 20% of pollen from heterozygote plants show aberrant division phenotypes.
