From: Internal ammonium excess induces ROS-mediated reactions and causes carbon scarcity in rice
Biological and physiological analyses of NH4+ excess responses of rice. Rice seedlings aged 7 d were subjected to NH4+ treatments for 14 d (a-c, e). a Fresh biomasses of roots and shoots. b Root-shoot ratios. c Free NH4+ content and e Total ROS content in response to NH4+ treatments. d Acute NH4+ excess simulation by treating with high NH4+ for 4 h in the presence of 1 mM MSX. Rice seedlings used for this experiment were 10 d old. Values indicated means ± SE of three independent replicates. ** and *** represented statistical significances at p<0.01 and 0.001, respectively
