Transmembrane ATPases are a class of plasma membrane-bound enzyme that catalyze the decomposition of ATP to ADP, leading to the liberation of free phosphate ions (Heguera and Beauge, 1997). ATPases are also involved in the import and export of various metabolites for different cellular functions and play important roles in overcoming various types of stresses to maintain cellular metabolism (Malofeeva et al., 2012). P. sojae ATPase was significantly up-regulated from 6 h after treatment (48% and 9% in treatment and control, respectively), indicating that the extract might act as stress in P. sojae.
