Abstract excerpt
Left-right asymmetry in plants can be found in helices of stalks, stems and tendrils, and in fan-like petal arrangements. The handedness in these asymmetric structures is often fixed in given species, indicating that genetic factors control asymmetric development. Here we show that dominant negative mutations at the tubulin intradimer interface of alpha-tubulins 4 and 6 cause left-handed helical growth and...
