-ROS accumulation after treatment of barley root pieces with laminarin from either Laminaria digitata (low frequency of β-1,6 linked branches) or E. bicyclis (high frequency of β-1,6 linked branches) was monitored by ROS burst assay. Treatment with Milli-Q water (mock) was used as control. Values represent mean ± SEM from eight wells.
