Functional parameters (Added by XJTU-China 2021)

As is shown in Fig.1 (Yin et al., 2017), the strength of Pgas is mainly dependent on the pH, while limited influenced by the types of acids.

(C) Fold changes in CAD expression at different pHs. Error bars represent the standard errors of the means of results for three biological replicates.

The author gives an equation with linear regression analysis to describe the relationship between the relative expression level and pH:
