Expression Pattern :

Pattern  Expression was observed in descendants of both ABalap and MSap. Reproducible beta-galactosidase was first observed in all four ABala granddaughters at the 55-cell (late 32 AB-cell) stage in embryos expressing the lag-2::lacZ reporter. Beta-galactosidase was not detected in any other cells of the AB lineage at this stage in development. Expression of beta-galactosidase was also observed in MSap descendants; at the 87-cell (64 AB-cell) stage, beta-galactosidase was observed in MSapa and MSapp, the daughters of MSap. Beta-galactosidase expression in both the ABala and MSap lineages persists for at least two rounds of cell division. This observation may reflect actual expression of the lag-2 gene, rather than a perdurance of beta-galactosidase protein, because an engineered beta-galactosidase with a short half-life was used in the construction of the translational fusion. No lag-2 expression were observed in ABalap and MSap, the proposed signaling cells of the ABplaa and ABplpa inductions, respectively. Instead, lag-2 expression was first detected at later stages, in descendants of these cells. Primary Identifier  Expr1611
