All authors analysed data. S.P. microinjected the majority of siRNA mixes, and identified, validated and characterized most genes; M.P. microinjected siRNA mixes, compared the developmental capacity and expression profile of oocytes grown in vitro and in vivo, and identified, validated and characterized several genes; V.K. microinjected siRNA mixes and wrote software in OriginPro to quantify phenotypes; T.T. validated and characterized Dusp7; B.S. did all bioinformatics analyses; V.K. and M.S. developed and established the strategy of the screen; M.S. wrote the manuscript; S.P., M.P., T.T. and B.S. commented on and edited the manuscript; M.P. and M.S. prepared the revised manuscript; M.S. supervised the study.
