Identification of candidate regulators of the mitotic-to-meiotic transition. A) The Stra8 expression pattern throughout embryonic ovary and postnatal testis development. Pink, embryonic ovary; blue, postnatal testis. B) Microarray expression profiles for all 142 Stra8-like candidate transcripts. C) The embryonic ovary and postnatal testis expression profiles for Esco2 (yellow), Setdb2 (blue), and Uba6 (green). For A–C, raw or normalized expression values recorded from the Affymetrix chip are given on the Y axis, with the X axis depicting sample sex and/or age. e, embryonic day; d, postnatal day.
