Suppression of nopo by mnk. (A-E)
Representative mitotic spindles in syncytial embryos from wild-type (A),
nopoZ1447 (B) and mnk nopoZ1447
females (C-E). (A-C) Microtubules are in green, DNA in red, and centrosomes in
blue. nopo (B) is suppressed by mnk, as evidenced by the
restoration of elongated spindles with attached centrosomes (C). (D,E)
Microtubules are in green and DNA in red. Aberrant mitotic figures with DNA
shared by two spindles are observed in mnk nopo-derived embryos.
(F,G) Cellularized embryos (2-3 hours). Actin is in green and
DNA in red. Developmental arrest of nopo is suppressed by
mnk. Cellularized mnk nopoZ1447-derived embryos
show large DNA masses (G) compared to wild type (F). Scale bars: 10 μm in
A-E; 20 μm in F,G.
