Function
In the dominant gain-of-function mutant tawawa1-D, the activity of the inflorescence meristem (IM) is extended and spikelet specification is delayed, resulting in prolonged branch formation and increased numbers of spikelets. In contrast, reductions in TAWAWA1 (TAW1) activity cause precocious IM abortion and spikelet formation, resulting in the generation of small inflorescences. TAW1 encodes a nuclear protein of unknown function and shows high levels of expression in the shoot apical meristem, the IM, and the branch meristem (BMs). TAW1 expression disappears from incipient spikelet meristems (SMs). It is demonstrated that members of the SHORT VEGETATIVE PHASE subfamily of MADS-box genes function downstream of TAW1. Thus, TAW1 is proposed as a unique regulator of meristem activity in rice and regulates inflorescence development through the promotion of IM activity and suppression of the phase change to SM identity [1].
Expression
Please input expression information here.
Evolution
TAW1 function might have evolved to ensure the production of sufficient numbers of spikelets. Unraveling the molecular function of TAW1 will provide an opportunity for a greater understanding of meristem activity and identity, which is a fundamental issue in plant biology. Furthermore, such knowledge could be exploited to further increase crop yields. In addition, TAW1 is of great interest with respect to the evolution of inflorescence architecture. TAW1 function may be essential for the development of compound inflorescences, in which the branching pattern is crucial [1].
