Differentially expressed orthologous genes exhibiting a conserved expression profile in rainbow trout and Xenopus. (A) Supervised clustering of expression profiles in the somatic layers of the ovarian follicle in rainbow trout and Xenopus during oocyte developmental competence acquisition: developmentally incompetent or poorly competent prophase I oocytes (NC1), developmentally competent prophase I oocytes (C1), and developmentally competent metaphase II oocytes (C2). For each species, the number of differentially expressed orthologous genes is indicated. (B) The expression profiles of specific genes are shown.
