Method P.322 left column 2nd paragraph: "Here, [Researchers] report the structome of S. cerevisiae strain S288c determined by freeze substitution and serial ultrathin-sectioning electron microscopy."
Comments P.330 left column bottom paragraph to right column 2nd paragraph: "The plasma membrane and membrane systems: The plasma membrane was ∼15.6 nm thick and consisted of three leaflets (Fig. 1a, Table 4). The outer leaflet was electron dense, the middle leaflet was electron transparent and the inner leaflet was electron dense. They measured ∼4.6, 3.8 and 7.3 nm, respectively (Table 4). The plasma membrane was invaginated into cytoplasm in certain places (Fig. 1b). There were 20–45 invaginations in each cell (Table 1). Membranes of S. cerevisiae might be classified into two groups according to their thickness. The first group had a thickness of 16–19 nm (Table 4) and included the plasma membrane (Fig. 1a), vacuolar membrane (Fig. 1o), membranes of autophagosomes (Fig. 1d) and multivesicular body (Fig. 1e). The second group had a thickness of 13–14 nm (Table 4) and included the outer and inner nuclear envelope (Fig. 1m), ER/Golgi membranes (Fig. 1a and g) and mitochondrial outer membrane (Fig. 1c)."
