M. auteur aut IRD text journalArticle eng text/pdf born digital access In rice, inflorescence architecture is established at early stages of reproductive development and contributes directly to grain yield potential. After induction of flowering, the complexity of branching, and therefore the number of seeds on the panicle, is determined by the activity of different meristem types and the timing of transitions between them. Although some of the genes involved in these transitions have been identified, an understanding of the network of transcriptional regulators controlling this process is lacking. To address this we used a precise laser microdissection and RNA-sequencing approach in Oryza sativa ssp. japonica cv. Nipponbare to produce quantitative data that describe the landscape of gene expression in four different meristem types: the rachis meristem, the primary branch meristem, the elongating primary branch meristem (including axillary meristems), and the spikelet meristem. A switch in expression profile between apical and axillary meristem types followed by more gradual changes during transitions in axillary meristem identity was observed, and several genes potentially involved in branching were identified. This resource will be vital for a mechanistic understanding of the link between inflorescence development and grain yield. specialized inflorescence development rice reproductive meristems RNA sequencing 076 86 1 75-88 2016 0960-7412 https://www.documentation.ird.fr/hor/fdi:010066855 10.1111/tpj.13147 0960-7412 [F B010066855] https://www.documentation.ird.fr/hor/fdi:010066855 https://www.documentation.ird.fr/intranet/publi/2016/05/010066855.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2016-06-02 2017-08-23 fdi:010066855 fre
