Atpase Localization

Adenosine triphosphatase (ATPase) activity has been shown to be associated with numerous physiological processes in both plants and animal cells. Biochemical studies have shown that in higher plants ATPase activity is high in cell wall preparations and is associated with the plasma membrane, nuclei, mitochondria, chloroplasts and lysosomes. However, there have been only a few ATPase localization studies of higher plants at the electron microscope level. Poux (1967) demonstrated ATPase activity associated with most cellular organelles in the protoderm cells of Cucumis roots. Hall (1971) has demonstrated ATPase activity in root tip cells of Zea mays. There was high surface activity largely associated with the plasma membrane and plasmodesmata. ATPase activity was also demonstrated in mitochondria, dictyosomes, endoplasmic reticulum and plastids.

The effect of colchicine on microtubules has been investigated in numerous cell types. In this present study we have used different concentrations of colchicine to determine if the two major groups of microtubules in plant cells, plasma membrane associated and mitotic, are differentially sensitive to this drug.Tomato seeds “Michigan forcing” were germinated on filter paper saturated with distilled water. Radicles 1.5 to 2.0cm were selected and placed into either distilled water or colchicine, 0.001, 0.01, 0.03, 0.04, 0.05, 0.1%, for 20 hrs. During this time they were kept at 20°C in dim light. Root tips were fixed in 3% glutaraldehyde in phosphate buffer at pH7.2 for lh at 4°C. After 5 rinses in buffer they were placed in 1% OsO4 in phosphate buffer at pH7.2 for 1h at 4°C. Root tips were then dehydrated in ethanol, treated with propylene and embedded in Epon.No growth occurred in any of the colchicine treated radicles. Observation of thin sections of control cells revealed many plasma membrane associated microtubules, many cells in division stages and the usual arrangement of cell organelles.

It is known that the product of the Golgi apparatus vesicles is deposited at and localized in the cell wall. This is accomplished by the formation of the hypertrophied dictyosomes and the subsequent movement of these vesicles to the plasma membrane (Fig. 1). After fusion with the plasma membrane, the secreted material is released into the cell wall area and, in some plants under appropriate conditions, moves outward through the cell wall and appears as a droplet on the root tip.In primary roots of Pisum sativum, var. Alaska (common garden pea) the Golgi apparatus vesicle product accumulates between the plasma membrane and the cell wall, particularly in those cells at the extreme tip of the root. These cells are formed at the acropetal end of the columella cells.
