Drought induces oxidative stress in pea plants
Jose F. Moran,Manuel Becana,Inaki Iturbe-Ormaetxe,Silvia Frechilla,Robert V. Klucas,Pedro M. Aparicio-Tejo +5 more
TL;DR: In this article, it was shown that increased levels and decompartmentation of catalytic metals occurring during water stress are responsible for the oxidative damage observed in vivo in leaves, i.e., increased levels of ascorbate, H2O2, and catalytic metal ions in leaves.

Rice Hemoglobins (Gene Cloning, Analysis, and O2-Binding Kinetics of a Recombinant Protein Synthesized in Escherichia coli)
Raúl Arredondo-Peter,M S Hargrove,Gautam Sarath,Jose F. Moran,J Lohrman,John S. Olson,Robert V. Klucas +6 more
TL;DR: The cloning and analysis of two rice hb genes, hb1 and hb2, that code for plant Hbs, suggest that this protein probably does not function to facilitate the diffusion of O2, and a mutation of the distal His demonstrates that this residue coordinates the heme Fe of ferric and deoxyferrous rHb 1 and stabilizes O2 in oxy-rHb1.

Crystal structure of a nonsymbiotic plant hemoglobin.
Mark S. Hargrove,Eric Allen Brucker,Boguslaw Stec,Gautam Sarath,Raúl Arredondo-Peter,Robert V. Klucas,John S. Olson,George N. Phillips +7 more
TL;DR: The bis-histidyl heme coordination found in riceHb1 is unusual for a protein that binds O(2) reversibly, however, the distal His73 is rapidly displaced by ferrous ligands, and the overall O( 2) affinity is ultra-high (K(D) approximately 1 nM).

Oxidative responses of resistant and susceptible cereal leaves to symptomatic and nonsymptomatic cereal aphid (Hemiptera: Aphididae) feeding.
Xinzhi Ni,Sharron S. Quisenberry,Tiffany Heng-Moss,John Markwell,Gautam Sarath,Robert V. Klucas,Frederick P. Baxendale +6 more
TL;DR: Different enzymatic responses in wheat, barley, and oat to D. noxia and R. padi feeding indicate the cereals have different mechanisms of aphid resistance, suggesting oxidative stress in plants is likely.
