Expression Pattern :

Pattern  In addition to recapitulating previously reported expression patterns [in the gonad from mid-L1 larval stage until around the L1/L2 molt in both sexes and from the L3 larval stage through adult in the hermaphrodite gonad in the spermatheca and sheath cells], this new construct revealed expression of FKH-6::GFP in 2-4 male gonadal cells in the L3 larval stage. This is the first report of FKH-6 expression in males after the L1/L2 molt. The expression of FKH-6::GFP in the gonad of the L3 male is reproducible, appearing in 54 of the 58 male animals observed during this time period, but the expression is short-lived, and coincides with the period when the proximal region of the migrating male gonad is extending past the distal tip of the gonad.
