Figure 1. Immunogold labeling of basal bodies and flagella of land plants.

A. Centrin localization in the lamella strip (ls) that subtends the band of microtubules (mt) and basal bodies (b) of Phaeoceros carolinianus, a hornwort. B. In the seed plant, Ginkgo biloba, centrin epitopes are localized in the lamellar strip (ls), amorphous zone (az) where the basal bodies insert and stellate pattern (sp) of the transition zone. C. Longitudinal section of the long stellate pattern in Ceratopteris basal bodies that label with anti-centrin. A faint outline of the stellate pattern is visible at the arrow. D. Cross section at the basal body of Ceratopteris showing centrin localizations in the stellate pattern and amorphous zone around the basal body. E. In Ceratopteris spermatogenous cells, gamma tubulin (arrows) localizes around the periphery of the blepharoplast following oryzalin treatment. Bars = 0.1 µm.
