Brassinosteroid signaling delimits root gravitropism via sorting of the Arabidopsis PIN2 auxin transporter

Brassinosteroid signaling can regulate auxin transport by influencing the sorting and accumulation of PIN auxin efflux carriers. Here, the authors show that in roots, brassinolide can modulate vacuolar degradation and endocytic sorting of PIN2, delimiting root curvature in response to gravity.
