Helical Growth

Have you ever wondered how vines can wrap around a pole as they grow? Helical growth is an important aspect of plant development, and is determined by specific patterns of cell expansion. Many plants with mutations in microtubule-associated proteins display defects in helical growth patterns. We are currently investigating how specific proteins regulate helical growth.

The ARMADILLO REPEAT KINESIN 2 mutant displays root skewing. We are investigating patterns of cell file rotation and microtubule dynamics to determine the function of this kinesin. Image by Jorge Holguin.
