Mealybug Chromosome Cycle as a Paradigm of Epigenetics
Figure 4
P. citri male meiosis. Meiotic sector from a testis of a third instar male. (a) DAPI-staining; (b) the same tissue patch, stained for DNA (pseudocolored in red) and for meiotic spindle, by an antibody against α-tubulin (pseudocolored in green). The DNA staining shows the metaphase I (arrow) and metaphase II (arrowheads) plates that can be distinguished on the basis of their different sizes (see Bongiorni et al., 2004, [37]). The meiotic spindle immunostainingstaining shows that meiosis II metaphase plates are associated with a monopolar spindle. Bar represents 10 μm.
