Haploid plants produced by centromere-mediated genome elimination
Making haploid plants — which inherit chromosomes from only one parent — is useful for genetic research and also, crucially, for plant breeding. A new method for generating haploid Arabidopsis plants is now described, involving the manipulation of a single centromeric protein, CENH3. When cenh3 null plants are crossed with wild-type plants, the mutant chromosomes are eliminated, producing haploid progeny.
