TISSUE CULTURE STUDIES AT PRESENT

Tissue Culture Studies

The content of ribo- and desoxyribonucleic acids in chick heart cultures at regular intervals after implanting has been determined both with standard culture medium and with Tyrode's solution alone. With an inadequate medium, both nucleic acids dropped in a consistent manner but ribonucleic acid was affected to a much greater extent. When the medium was adequate for growth, both fractions rose ...

Tissue Culture of Rubber: Past, Present and Future Prospects

In rubber, the current propagation method of grafting on to unselected seedlings, maintains intraclonal heterogeneity for vigour and productivity and hence a great improvement may be expected by using micropropagation in vitro. Micropropagation with nodal and shoot tip explants derived from seedlings are possible as with mature clonal explants. The major problem in using clonal material from ma...

Oxidative Stress Studies in Plant Tissue Culture

Higher plants are sessile therefore are continuously exposed to different environmental stress factors, such as drought, salinity, heavy metals, nutritional disorders, radiation without any protection. Most of these stresses produce certain common effects on plants, like induced oxidative stress by overproduction of reactive oxygen species (ROS), besides their own specific effects (Rao, 2006). ...

Tissue Culture Studies on Bacterial Hypersensitivity

1. Mononuclear exudative cells, obtained from tuberculous guinea pigs by the intrapleural injection of parowax, exhibited characteristic sensitivity to the toxic action of tuberculin when tested in tissue culture. 2. Experiments with these cells, practically free of body fluids, show conclusively that sensitivity to tuberculin is an inherent characteristic of mesenchymal cells from tuberculous ...
