Microfilament bundles associated with tubular endoplasmic Reticulum in fusiform cells in the active cambial zone ofFraxinus excelsior L.
Tóm tắt
In the active cambium ofFraxinus excelsior L. microfilament bundles and tubular endoplasmic reticulum appear always associated with each other in the parietal cytoplasm of fusiform cells. The two associated organelles are parallel to the longitudinal cell axis. The association is absent in small, isodiametric ray cells. It is suggested that the associations are specialized structures related to the strong longitudinal cytoplasmic streaming in active elongated cells.
