Fig. 5: The organization of cowpea centromeres during microgametogenesis.
From: Unequal contribution of two paralogous CENH3 variants in cowpea centromere function
a, b CENH3.1 (green) and CENH3.2 (red) localize in the centromeres of early-stage mononucleate pollen. Further enlarged nuclei are shown as insets. c, d In mature binucleate pollen, the vegetative nucleus shows no centromeric CENH3.1 (green) and CENH3.2 (red). Centromeric CENH3.1 (green) localizes in the generative nucleus of mature pollen (c), while CENH3.2 (red) does not (d), suggesting specific removal.
