Abstract

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 de..
