RNAi of <i>Nxt1</i> in spermatocytes phenocopies the <i>Nxt1^z2-0488</i> defect.

<p>(A) Expression of an <i>Nxt1</i> RNAi hairpin construct in the male germline causes a highly penetrant meiotic arrest phenotype. (B) Q-RT-PCR reveals that expression of <i>Nxt1</i> target genes is reduced in <i>Nxt1</i> RNAi testes (dark bars), and that the effect is similar to that seen in <i>Nxt1^z2-0488</i>/<i>Nxt1^DG05102</i> mutant testes (light bars).
