| Abstract: | Immunofluorescence staining was used to observe the microtubules in root tip of Camptotheca acuminata seeding,including meristematic zone,elongation zone and maturation zone.Results show that the microtubules of the cells in the meristematic zone are randomly arranged and densely surround the nucleus.The microtubules exist in the two poles of the cells in the elongation zone,and the microtubules of the cells in the maturation zone present an inclined parallel structure or a spiral network structure. |
