Lateral roots emerge from the primary root at right angles but briefly grow asymmetrically to set a distinct growth angle. Here Waidmann et al. show that cytokinin acts as an anti-gravitropic signal that impairs growth on the upper side of emerged la

Directional organ growth allows the plant root system to strategically cover its surroundings. Intercellular auxin transport is aligned with the gravity vector in the primary root tips, facilitating downward organ bending at the lower root flank. Her

Time-lapse imaging of roots is highly suitable for depicting gravitropic growth behaviors. However, roots may show faster or slower bending kinetics when compared to control as a result of differences in overall root growth. Accordingly, conditions t
