Additional Descriptive Data
fs(1)Yb transcripts are detected in all stages tested on northern blots (third instar larvae, pupae, and adults). In females, they are detected weakly in third instar larvae, are more abundant in pupae, and decrease in adults. In males, they are highest in third instar larvae and decrease in the pupal and adult stages. fs(1)Yb transcripts are detected by in situ hybridization in ovarioles in the terminal filament and the epithelial sheath that envelopes the terminal filament.

          Other Comments
          fs(1)Yb is required for both germline stem cell and somatic stem cell divisions in the ovary.
          fs(1)Yb is required for the maintenance of germline stem cells during oogenesis. The function of fs(1)Yb is soma-dependent.
          fs(1)Yb is required in the soma for ovary follicle cell differentiation and to support later stages of egg maturation. Mutations at fs(1)Yb show genetic interactions with the N group of neurogenic genes.
          Mitotic germline recombination demonstrates that fs(1)Yb is soma- dependent.
          fs(1)Yb gene product affects the asymmetric division of the female germline stem cell (GSC).
          fs(1)Yb is required for oogenesis and embryogenesis. It is tightly linked to fs(1)Ya.
