Do microtubules influence growth responses to environmental stimuli in plants? Microtubules (MTs) have numerous roles in plant development and these functions are assisted by Microtubule Associated Proteins (MAPs). To further explore MT function we study a MAP called END BINDING 1 (EB1). Previous analysis of eb1 mutants indicates root defects in responses to mechanical stimulation (MS) and/or gravity. To determine whether EB1 activity contributes to root responses to MS or gravity or both, two approaches were taken. First, I analyze the effects of altering the type and amount of MS perceived by the root. Second, I analyzed double mutants between eb1b and plants carrying mutations in genes associated with responses to MS and gravity. Results from both approaches suggest that EB1 has a role in root responses to MS and an indirect role in responses to gravity.
