We also determined the protein level of BADH and CMO-like in the sixth leaf blades and roots of L. chinensis and barley plants treated with 0 and 300 mM NaCl for 72 h. The protein level of BADH and CMO-like was greater in the leaves of both plants than in the roots (Figure 6b). The amount of BADH and CMO-like proteins was greater in L. chinensis than in barley under normal conditions. On the other hand, the expression level of BADH protein was increased in barley but not in L. chinensis in the presence of NaCl. We also determined BADH activity using crude protein extracted from the sixth leaf blades of L. chinensis plants. The BADH activity in L. chinensis leaves under normal and saline conditions was 0.51 and 0.54 nmol min−1 mg−1 protein, respectively, which was much higher than the activity in barley leaves (0.03 and 0.11 nmol min−1 mg−1 protein under normal and saline conditions, respectively) (Ishitani et al. [1993]) (Table 3).
