Anther of an Arabidopsis plant in which a pollen killer is present
This pollen killer, observed within local natural populations of Arabidopsis thaliana, cheats Mendel’s inheritance laws in the progeny of hybrids because an allele possessing poison and antidote genes provokes the death of the pollen grains that do not carry them. Here, Alexander staining of the anther reveals the pollen viability: pollen grains with the killer allele are viable and colored in red while dead pollen grains appear blue. See Ricou et al.
