Studies have shown that of the organic acids, citrate is one of the most effective in solubilizing P in the soil [183]. Furthermore, the amount of phosphoprotein phosphatase 2A (PP2A) isoform 4 significantly increased in 99038 roots compared to Qi-319. In Arabidopsis, PP2A was shown to participate in hormone-mediated growth regulation, control of cell shape and plant morphology, regulation of the cell cycle, and elongation of root cortex cells [184, 185]. 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.

Many of these aquaporins show a cell-specific expression pattern in the root. It has been shown that aquaporins play a major role in facilitating the roots’ capacity to alter their water permeability in response to stress [69]. These rapid changes are accounted for by the aquaporin-mediated changes in cell membrane permeability [70]. In rice, the PM aquaporin RWC3 was upregulated in upland rice 10 h after the water deficit, possibly by providing the cell with increased water uptake to maintain cell turgor during deficit [71].

In the same study, it also showed upregulation during rice blast fungus infection [40]. A more recent study reported the increased expression of PR10 in the roots during drought stress and ABA-treatment [41]. Amino acid sequence of RSOsPR10 revealed homology with another protein OsPR10a/PBZ and showed similar functions during stress; however, the latter is expressed in the shoots, indicating organ-specific regulation [40]. MALDI-TOF MS was also used to identify 22 major proteins that were significantly upregulated during drought [42].
