Over-expression of genes with effects on silencing.

a– Bold, lines recovered in screens; non-bold, candidate lines.
b– * an genomic insertion site was not identified by iPCR.
c– severity of silencing was scored in ranks from severe silencing (1) to no silencing (6).
d– eye color after w+ knockdown ('++' amount in controls, '+++' increased, '+' reduced).
e– rough eyes.
f– small eyes.
g– lethal in males.
h– pupal lethal.
i– sectors of complete de-repression in a speckled background.
