Figure 1. Immunogold labeling of Pma1 in the plasma membrane of S. cerevisiae SEY6210.

(A) – glucose-starved cells, Pma1 was distributed in the membrane as single structures; (B) – cells that had metabolized glucose for 15 min, Pma1 formed large bunch-like complexes; (C) – enlarged fragment of photograph (B) CW = cell wall; PM = plasma membrane.
