Functional Characterization of Date Palm Aquaporin Gene PdPIP1;2 Confers Drought and Salinity Tolerance to Yeast and Arabidopsis.

ABSTRACT: Recent studies on salinity tolerance in date palm revealed the discovery of salt-responsive genes including PdPIP1;2, a highly conserved aquaporin gene in plants, which was functionally characterized in this study to investigate its precise role in drought and salinity tolerance. Immunoblot assay showed a high level of PIP1 protein accumulation only in the leaves of date palm plants when grown under drought, an observation which may imply the involvement of PIP1;2 in CO₂ uptake. Heterologous overexpression of PdPIP1;2 in yeast (Saccharomyces cerevisiae) improved tolerance to salinity and oxidative stress. While, heterologous overexpression of PdPIP1;2 in Arabidopsis had significantly (p < 0.05) increased biomass, chlorophyll content, and root l
