Deletion mutations in the αN helix of the CENH3 histone fold domain result in haploid induction on outcrossing

Plants carrying the mutant allele transgenically and null for the endogenous gene were pollinated by a CENH3 wild‐type Ler gl1‐1 pollen donor. Haploids were scored using the glabrous phenotype as a proxy. Haploids were scored using the glabrous phenotype, and % is among viable offspring.
