[Mineral composition of cultured Ginseng cells].

The contents of macroelements and microelements in ginseng roots and callus cultures was determined by atom absorption spectroscopy. Ginseng cells and tissues were shown to accumulate considerable amounts of microelements. The content of six of eleven mineral components studied (K, Ca, Na, Mo, Mn, and Cr) in callus cultures was higher than that in roots of agricultural ginseng plants.

[The interaction of Yersinia, Listeria and Salmonella with plant cells].

The results of the interaction of bacteria of the genera Yersinia, Listeria and Salmonella, pathogenic for humans and animals, with callus cultures of different plant species are presented. As revealed in this study, complicated interactions developed between bacteria and plant cells. Plant cells were shown to be highly sensitive to the action of bacteria.
