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.

Figure 2
The expression pattern of RSTK, H+-ATPase, ISCP, UCP1, and UCP2 in tissues of AC Hime and Westag 97 exposed to different Cd concentrations at different times. Control: 0 μM Cd, High: 1.6 μM Cd, two sampling times at the 2 and 22 h. Each data point is the mean of the two biological replicates with three technical replicates. The bar represents the standard error (n = 3). The value that is statistically different at P < 0.05 is indicated by ‡ (AC Hime) and ∗ (Westag 97), respectively.

Expression stability (M) and ranking of ten candidate reference genes after two soybean cultivars were exposed to different Cd concentrations for two time courses. M values were calculated by geNorm following stepwise exclusion of the least stable gene (highest M value) across all 24 samples.
