title: A role of phosphorylase in the potato minituber function under altered gravity.
abstract: The goal of our work was a role of phosphorylase (EC. 2.4.1.1) in starch accumulation in plastids of storage parenchyma cells in potato minitubers forming under clinorotation. An increased enzyme activity under the influence of simulated microgravity has been revealed by using the biochemical and electron cytochemical methods. The obtained results suggest the correlation between an increase in phosphorylase activity and acceleration growth rate and senescence of plant storage organs in microgravity.
