| Popis: | The presence of extracellular microtubules on the microvillar surface of the intestine of a number of aphids was noted as early as 1972. The authors stated, “At present there is little evidence as to the true nature of these extracellular microtubules. We have used the term microtubule in the broad sense.” These microtubules are smaller than cytoplasmic microtubules reported earlier.In the present investigation we have studied the intestinal epithelium of the green pea aphid, A. pisum, using transmission electron microscopy. The epithelium consists of a single layer of pyramidal shaped cells with a striated border. In the anterior part of the intestine the striated border consists of a microlabyrinth (Fig. 1) similar to that previously described for the green peach aphid, Myzus persicae. In some regions of the microlabyrinth the microtubules are arranged at right angles to the length of the infoldings; in other regions microtubules run parallel to the length of the infoldings giving support to this structure. |
