Figure 2. Essential and lethal genes.

Figure 2

(a) For more than 56% of the injected genes, phenotypes were observed. The pupal injection screen revealed phenotypes for a larger portion of genes compared with the larval injection screen. (b) Death of the injected animals was scored 22 days post injection (larval injection; blue circle) and 11 days post injection (pupal and larval injection; dark green and hatched blue circles). Note that embryonic lethality is based on maternal and zygotic gene knockdown. ‘Parental lethal': death of the injected animal. (c) Selected phenotypic categories after pupal injection. Embryonic lethal injections are further categorized showing that more than half of the embryonic lethal genes lead to abortion of embryogenesis before cuticle secretion. (d) Phenotypic categories after larval injection. ‘Defects during the process of metamorphosis': metamorphosis not completed or entered precociously. Insets: relations to the entire data set.
