Interactive effects of exogenous melatonin and selenium on the enzyme activities and phosphate/silicon transporters. Effects of different treatments of exogenous melatonin (MT) (0 μM, 50 μM and 100 μM) and selenium (Se) (0 μM, 50 μM, 100 μM and 200 μM) on the activities of (a) superoxide dismutase (SOD), (b) catalase (CAT), (APX) ascorbate peroxidase (APX), and (d) glutathione reductase (GR) in the leaves and roots, and (e) phosphate (OsPT2)/silicon influx (Lis2) transporters in the roots of Brassica napus cv.
