Periodic Reporting for period 1 - GainGrain (Understanding genetic hubs in rice inflorescence architecture to increase grain yield)
Reporting period: 2019-05-01 to 2021-04-30
Domesticated rice (Oryza sativa L.) is a staple crop and by far the most convenient model cereal for research. Often, the knowledge and tools developed in rice can be transferred and validated in other common and ‘orphan’ cereals.
Rice has a complex inflorescence (panicle) whose architecture is established by iterations of branching, and is built by a group of undifferentiated, actively dividing cells forming the inflorescence meristem. The more branched is the inflorescence, the more grain it can produce. Therefore, if we could control inflorescence meristem activity to make more branched and/or longer inflorescence, with more room to set grain, we should be able to produce significant yield increases. Several genes that regulate rice inflorescence meristem activity have been already discovered, but only a very few of them could be used to make more productive plants. To fully exploit the potential of these genes for crop breeding, we need to advance our theoretical knowledge about how they work and are connected, which is the aim of this action, ‘GainGrain’.
