      Comments

      Expression of one copy of SmnF70S.T:Zzzz\FLAG partially rescues the larval lethality seen in homozygous SmnX7 mutants.

      Co-expression of one copy each of SmnG210V.T:Zzzz\FLAG and SmnF70S.T:Zzzz\FLAG partially rescues the larval lethality seen in homozygous SmnX7 mutants, but results in more severe phenotype than when SmnF70S.T:Zzzz\FLAG is expressed alone; a few adults eclose but most animals reach the pupal stage.
