Prior to division, YFP- LIN-45 expressed from fosmid[yfp-
lin-45] was evident in the cytoplasm of all VPCs. In contrast, at the Pn.px and later stages, YFP-LIN-45 was markedly reduced in the descendants of P6.p compared with the descendants of P5.p and P7.p. YFP-LIN-45 expressed from fosmid[yfp-
lin-45] or the
lin-31p::yfp-
lin-45 tissue-specific reporter stably accumulated in P6.p descendents in a
sel-10(0)-null mutant.Expression of YFP-LIN-45 was stabilized in P6.p in a second null mutant, sel- 10
(ok1632).
