Ribosome content in wheat triticum aestivum shoot apex cells in the vegetative phase and during transition to the generative phase



Ribosome content in wheat triticum aestivum shoot apex cells in the vegetative phase and during transition to the generative phase



Tsitologiya i Genetika 13(4): 252-257



Changes in ribosome density, in the amount of polysomes and attached ribosomes were studied in EM photographs in different zones of wheat shoot apex during ontogenesis, from a seed embryo to the beginning of spike formation. Ribosome density decreases in the apical zone during the decrease in its activity at the vegetative phase and considerably increases at the prefloral phase, before the transition to the generative development. At that time changes in the nucleolus structure and an increase in RNA and protein contents were also observed.
