From: YA is needed for proper nuclear organization to transition between meiosis and mitosis in Drosophila
Phospho-histone H3 distribution on chromatin of wildtype and YA-deficient embryos. Immunostaining of 0–15 minute old wildtype and Ya2 embryos. DNA shown in red, phospho-histone H3 in green. Embryos shown had three peripheral nuclei (not shown) and two nuclei apposed in the mid-anterior region. Apposed nuclei are shown. (A) Wildtype, (B) Synchronous apposed nuclei in a Ya2 embryo (70% of Ya2 embryos with apposed nuclei showed this phenotype), (C) Asynchronous apposed nuclei in a Ya2 embryo (30% of Ya2 embryos with apposed nuclei showed this phenotype). Wildtype n = 22 embryos with apposed pronuclei. Ya2 n = 27 embryos with apposed nuclei. Bar = 10 μm.
