Red and blue light antagonistically regulate tomato root system architecture by the auxin-mediated SlARF18-SlDRO1 module.
Root system architecture (RSA) is critical for water and nutrients uptake and is affected by light. However, the precise mechanisms by which light quality regulates RSA remain obscure. Here, we showed that red light (R) caused shorter primary root, larger lateral root angle and lower expression of DEEPER ROOTING 1 (SlD...
