We have identified mutants for five AtyCA genes. In this report we present two null mutants mapping at yCA5 loci and yCA5 loci. Homozygous and heterozygous null mutants were isolated and examined for phenotypic characteristics over at least two generations. Vegetative growth is not apparently affected while reroductive phace is impaired, mainly in pollen development.Anthers are full of pollen grains that apparently are arrested at tetrad stage.
