Malate exudation rate in soybean hairy roots and Arabidopsis overexpressing SgMDH1. A, Malate exudation rate in soybean hairy roots. CK indicates soybean hairy roots transformed with the empty vector. OX indicates soybean hairy roots overexpressing SgMDH1. B, Malate exudation rate in Arabidopsis. WT indicates the wild-type Columbia ecotype of Arabidopsis. OX1, OX2, and OX3 are three transgenic lines overexpressing SgMDH1. Each bar represents the mean of four independent replicates with se. Asterisks indicate significant differences between the control and the SgMDH1 overexpression lines at the P = 0.05 level. A single asterisk indicates 0.01 < P < 0.05. FW, Fresh weight.
