Dixon et al. (2020) report a novel role for the TB1 transcription factor gene in wheat, controlling plant height. This gene and its orthologues have long been known to affect branching in a number of crops and plant species. Its involvement in the determination of plant height opens up new avenues for the modification of this key trait, which affects multiple agronomic aspects of annual crops, from emergence to harvest index.
