Drosophila Staged follicles

ABSTRACT: Gene expression analysis of yw follicles at S9/10a, S10B, S12, and S14; Gene expression analysis of pxt mutant follicles (f01000 and EY03052) at S10B, S12, S14 Drosophila ovarian follicles complete development using a spatially and temporally controlled maturation process in which they resume meiosis and secrete a multi-layered, protective eggshell before undergoing arrest and/or ovulation. Microarray analysis revealed more than 150 genes that are expressed in a stage-specific manner during the last 24 hours of follicle development. These include all 30 previously known eggshell genes, as well as 19 new candidate chorion genes and 100 other genes likely to participate in maturation. Mutations in pxt, encoding a putative Drosophila cyclooxygenase, cause many transcripts to begin expression
