Abstract
Abstract Zinc deficiency remarkably depressed the growth of cultured tobacco cells. When the zinc concentration in the cells decreased to a level of less than 70 μg/g DW, the 80S ribosome content of the cells was remarkably reduced. The decrease in the zinc concentration to a level of less than 50 μg/g DW caused a decrease in the protein content. SDS-PAGE patterns of proteins showed that the composition of the protein remained almost unchanged, although the amount was remarkably reduced.
