Additional Descriptive Data

During oogenesis, yemα transcript is first detected in germarium region 2, in the presumptive oocyte. Before stage 8, expression is detected in the posterior pole of the oocyte, while expression is detected in the anterior pole at stages S8-S10A. From stage S10B on, expression is uniform in the oocyte.

(Capri et al., 1997)

The 4.5 kb yemα transcript is maternal. It is abundant in the ovary and in pre-gastrulation embryos.

(Ait-Ahmed et al., 1990)

The 4.5 kb yemα transcript localizes to the periphery of the oocyte nucleus at stage S7 of oogenesis. By stage S8, when the nucleus starts migrating dorsally, transcripts are localized anteriorly. The anterior localization is maintained until at least stage S10A of oogenesis. At stage S10B, localization becomes uniform. The transcripts are localized uniformly in the preblastoderm embryo. Transcript levels are lower in the syncytial blastoderm embryo, barely detectable during gastrulation, and not detected after gastrulation.
