Annulate lamellae in phloem cells of virus-infected Sonchus plants

The occurrence of annulate lamellae (AL) in differentiating phloem of Sonchus oleraceus (Compositae) singly infected with sowthistle yellow vein virus (SYVV) and doubly infected with a combination of SYVV and beet yellow stunt virus is documented by electron microscopy. Cell types in which AL were found were immature sieve elements and phloem parenchyma cells. AL were found only in cells that a...

Annulate Lamellae in Sarcoma I Cells

Annulate lamellae have been observed in eggs of marine invertebrates (1, 6, 12, 13, 18), rat spermatids (11, 17), crayfish spermatocytes (15), the amphibian pancreas (17), the adrenal cortex of the fetal rat (14), Sarcoma 37 cells (4), HeLa cells (5), Ehrlich and Yoshida ascites tumor cells (20), m ammary carcinoma cells of the rat (16), and cells of a chicken fibrosarcoma (3). Neither the orig...

Annulate lamellae: comparison of antigenic epitopes of annulate lamellae membranes with the nuclear envelope

Annulate lamellae (AL) are a membranous structure frequently observed in differentiating gametes and tumor cells. In spite of numerous morphological studies, the function and biochemical composition of this membrane system are not well understood. In this study, we have examined the AL membrane system of vinblastine-treated mouse L cells using immunocytochemistry and Western blot analysis. Our ...

Fine Structure of Annulate Lamellae

Annulate lamellae represent a poorly understood class of cytomembranes (see references 14-18). The structural resemblance and proximity (in some cases) between the nuclear envelope and annulate lamellae have led to the concept that the annulate lamellae represent a product of the nuclear envelope although the methods propoundedly involved in the morphogenesis of annulate lamellae are indeed var...

The Fine Structure of Annulate Lamellae

Certain lamellar structures have been described from snail (Otala) and clam (Spisula) oocytes, the acinar cells of amphibian (Ambystoma) pancreas, and from rat spermatids. These structures are alike in possessing numerous rings or annuli, resembling those in the nuclear membrane. Thus the name "annulate lamellae" has been proposed for them. It is suggested that they may function in the transfer...
