Bottom Line: Westag 97 has larger capacity of Cd accumulation in roots which prevents Cd from translocating into stems and leaves; conversely, AC Hime has smaller capacity of Cd accumulation in roots; more Cd is transported into stems and leaves.The different capacity of Cd in roots between Westag 97 and AC Hime causes the different Cd concentration in seeds.Meanwhile, according to the different expression levels of RSTK, ISCP, and H(+)-ATPase between Westag 97 and AC Hime, RSTK may be involved in transporting Cd into stems and leaves; H(+)-ATPase may be correlated to the capacity of Cd accumulation in roots; and Cd caused some changes of fundamental life process which leaded to the different expression patterns of ISCP between Westag 97 and AC Hime.

ABSTRACT
Westag 97 has larger capacity of Cd accumulation in roots which prevents Cd from translocating into stems and leaves; conversely, AC Hime has smaller capacity of Cd accumulation in roots; more Cd is transported into stems and leaves. The different capacity of Cd in roots between Westag 97 and AC Hime causes the different Cd concentration in seeds. Meanwhile, according to the different expression levels of RSTK, ISCP, and H(+)-ATPase between Westag 97 and AC Hime, RSTK may be involved in transporting Cd into stems and leaves; H(+)-ATPase may be correlated to the capacity of Cd accumulation in roots; and Cd caused some changes of fundamental life process which leaded to the different expression patterns of ISCP between Westag 97 and AC Hime.

Mentions: The Cd concentrations of all samples collected from the control (0 μM) treatment were below the detectable limit. As shown in Figure 1, the amount of Cd accumulation in roots of Westag 97 (19.820 ± 0.554 mg/kg) was significantly higher (P = 0.0002) than that of AC Hime (9.730 ± 1.253 mg/kg) on the 17th d after Cd treatment. Conversely, the Cd concentration in leaves and stems of AC Hime (0.803 ± 0.164 mg/kg and 2.343 ± 0.541 mg/kg, resp.) was significantly higher (P = 0.0014 and 0.0052, resp.) than that in leaves and stems of Westag 97 (0.03 ± 0.011 mg/kg and 0.393 ± 0.272 mg/kg, resp.). Similar results were detected on the 22nd d. The Cd concentration in the roots of Westag 97 (23.277 ± 0.460 mg/kg) was also significantly higher (P = 0.00013) than that in roots of AC Hime (6.887 ± 0.611 mg/kg). The Cd concentration in leaves and stems of AC Hime (0.517 ± 0.0151 mg/kg and 0.940 ± 0.330 mg/kg, resp.) was significantly higher (P = 0.00014 and 0.0213, resp.) than that in leaves and stems of Westag 97 (0.033 ± 0.0571 mg/kg and 0.117 ± 0.200 mg/kg, resp.).
