EB1 reveals mobile microtubule nucleation sites in Arabidopsis

Jordi Chan , Grant M. Calder , John H. Doonan & Clive W. Lloyd

In plants, it is unclear how dispersed cortical microtubules are nucleated, polarized and organized in the absence of centrosomes. In Arabidopsis thaliana cells, expression of a fusion between the microtubule-end-binding protein AtEB1a and green fluorescent protein (GFP) results in labelling of spindle poles, where minus ends gather.
