Phospholipid analysis of tobacco cell plasma membranes. (A) Percents of different phospholipids of plasma membranes from CM-treated cells relative to control cells. The CM/Control ratio for PS+PI was significantly different from that for PE+PG (p < 0.05). (B) Fatty acid composition of plasma membranes isolated from control and CM-treated cells. Dark grey bars, control cells; light grey bars, CM-treated cells. Values used are averages of two plasma membrane preparations and error bars denote SD.
