However, the mechanism by which they are quantitatively controlled is unknown. We show that the amount of mature miR-9, a key regulator of neuronal development, increases during zebrafish neurogenesis in a sharp stepwise manner. We characterize the spatiotemporal profile of seven distinct microRNA primary transcripts (pri-mir)-9s that produce the same mature miR-9 and show that they are sequentially expressed during hindbrain neurogenesis. Expression of late-onset pri-mir-9-1 is added on to, rather than replacing, the expression of early onset pri-mir-9-4 and -9-5 in single cells. CRISPR/Cas9 mutation of the late-onset pri-mir-9-1 prevents the developmental increase of mature miR-9, reduces late neuronal differentiation and fails to downregulate Her6 at late stages. Mathematical modelling shows that an adaptive network containing Her6 is insensitive to linear increases in miR-9 but responds to stepwise increases of miR-9. We suggest that a sharp stepwise increase of mature miR-9 is created by sequential and additive temporal activation of distinct loci. This may be a strategy to overcome adaptation and facilitate a transition of Her6 to a new dynamic regime or steady state."}],"has_accepted_license":"1","keyword":["Developmental Biology","Molecular Biology"],"oa_version":"Published Version","article_number":"dev200474","scopus_import":"1","month":"10","file":[{"content_type":"application/pdf","checksum":"d7c29b74e9e4032308228cc704a30e88","file_id":"12438","success":1,"date_created":"2023-01-30T08:35:44Z","date_updated":"2023-01-30T08:35:44Z","creator":"dernst","access_level":"open_access","file_size":9348839,"relation":"main_file","file_name":"2022_Development_Soto.pdf"}],"publication_status":"published","date_updated":"2023-08-04T09:41:08Z","date_created":"2023-01-16T09:53:17Z","language":[{"iso":"eng"}],"issue":"19","publication_identifier":{"eissn":["1477-9129"],"issn":["0950-1991"]},"year":"2022","volume":149,"acknowledgement":"We are grateful to Dr Tom Pettini for the advice on smiFISH technique and Dr Laure Bally-Cuif for sharing plasmids.
