MLH1 Immunolocalization in PMCs of the ArAr Diploid ([A]–[C]), ArAr′CoCo Allotetraploid ([D]–[F]), and ArAr′Co Allotriploid ([G]–[L]) Hybrids.
Chromosomes at diakinesis stage were stained with DAPI (red) and the Arabidopsis MLH1 antibody (green). (C), (F), (I), and (L) were generated by merging DAPI and anti-MLH1. Arrows indicate multivalents, and asterisks show univalents. Bars = 10 μm.
