Researchers identify key genes controlling rice tiller angle

Rice tiller angle is an important trait affecting population structure, light utilization, planting density, and yield potential. Although several genes affecting tiller angle have been reported, the upstream regulatory networks connecting gravity sensing and hormone distribution have remained largely unknown. Researchers from the Hefei Institute of Physical Science of the Chinese Academy of Sciences have identified a key molecular module that regulates rice plant architecture. Their study is published in Plant Communications.
