To assess the functional importance of ribosomal protein rpA1 gene expression during development of Drosophila melanogaster, we have transformed into the fly's genome an antisense rpA1 gene driven by a heat shock promoter. Antisense rpA1 expression severely disrupted oogenesis and produced a 'small egg' female-sterile phenotype. The severities of these defects were proportional to the level of antisense rpA1 expression. Anti-rpA1 expression did not affect larval or pupal development. Quantitative RNA analysis suggested that high anti-rpA1 expression results in a general decrease of mRNA in the ovary.
