TY - T1 - Apoplastic Hydrogen Peroxide in the Growth Zone of the Maize Primary Root. Increased Levels Differentially Modulate Root Elongation under Well-Watered and Water-Stressed Conditions SN - / UR - http://hdl.handle.net/10138/315777 T3 - A1 - Voothuluru, Priya; Mäkelä, Pirjo; Zhu, Jinming; Yamaguchi, Mineo; Oliver, Melvin J.; Simmonds, John; Sharp, Robert A2 - PB - Y1 - 2020 LA - eng AB - Reactive oxygen species (ROS) can act as signaling molecules involved in the acclimation of plants to various abiotic and biotic stresses. However, it is not clear how the generalized increases in ROS and downstream signaling events that occur in response to stressful conditions are coordinated to modify plant growth and development. Previous studies of maize (Zea mays L.) primary root growth under water deficit stress showed that cell elongation is maintained in the apical region of the growth ...
