Forming GSH-Cu complexes. A Cu/Zn-SOD and a GLP were also observed to be upregulated in both varieties. Some GLPs are known to act as SODs, which are metalloenzymes that catalyze the dismutation of the highly reactive superoxide ions (OÁ− 2 ) to H2O2 and O2 [160, 161]. The induction of these proteins with SOD activity in Cu-stressed rice roots implies that they play a role in the first line of defense against ROS. It is also interesting to note that four of the identified differentially expressed proteins were PR proteins which were upregulated in the roots of the Cu-tolerant variety.

Taken together, the enhanced production of citrate and upregulation of PP2A in the roots of 99038 plants might explain its observed tolerance to P starvation compared to the Qi-319 wild type. In rice roots, proteomic analysis revealed ten P starvation responsive proteins involved in metabolism and defense or stress response [176]. One of the two upregulated proteins under low P supply was identified as a member of the PR-10 family, which are generally known to have RNase activity and in most cases, are involved in defense response and plant development [186, 187].

Annexins are expressed throughout the plant body and many have been found in the roots [92, 93]. In Arabidopsis, annexins are responsible for the root epidermal PM Ca2+- and K+ permeable conductance that is activated by extracellular hydroxyl radicals. In a study by Laohavisit et al. [90], annexins were observed to respond to high extracellular NaCl by mediating ROS-activated Ca2+ influx across the PM of root epidermal protoplasts. 2 Cereal Root Proteomics for Complementing the Mechanistic … 29 Roots are the primary tissues affected by salinity stress.
