Differential expression of sodium membrane transport pumps in P. polycephalum under salt stress. (a) Up-regulated sodium transporters located in the plasma membrane and vacuolar membrane, facilitating sodium ion efflux to maintain intracellular ion homeostasis (fold changes: 3.86, 2.96). (b) Down-regulated sodium transporters in the plasma membrane, likely reducing sodium influx to prevent further intracellular accumulation (fold changes: -2.34, -2.60). Arrows indicate the direction of sodium ion movement across the membrane.
