- Key message
- The expression of water channel protein RWC3 mRNA was increased in upland rice at the early response (up to 4 h) to the 20% polyethylene glycol (PEG) 6000 treatment, whereas there was no significant expression changes in lowland rice
- Partial silencing of the water channel genes, OsPIP1;1 and OsPIP1;3, reduced seed germination while over-expression of OsPIP1;3 promoted seed germination under water-stress conditions
- Moreover, spatial expression analysis indicates that OsPIP1;3 is expressed predominantly in embryo during seed germination
- Exogenous NO stimulated the transcription of OsPIP1;1, OsPIP1;2, OsPIP1;3 and OsPIP2;8 in germinating seeds
- The up-regulation of RWC3 in upland rice fits well with the knowledge that upland rice adopts the mechanism of drought avoidance
- These results indicated that RWC3 probably played a role in drought avoidance in rice
- The role of aquaporin RWC3 in drought avoidance in rice
- Immunocytochemistry showed that OsPIP1;3 majorly accumulated on the proximal end of the endodermis and the cell surface around xylem
- Further experiment suggested that heterologous expression of OsPIP1;3 in cyanobacterium promoted bacterial growth in the condition with different CO2 gas supply
- Here, from a drought-resistant rice cultivar, we isolated an OsPIP1;3 gene SNP which is mostly expressed in rice roots, and is strongly responsive to drought stress
- Expression of GFP-OsPIP1;3 alone in Xenopus oocytes or rice protoplasts showed OsPIP1;3 mislocalization in ER-like neighborhood, whereas co-expression of OsPIP2;2 recruited OsPIP1;3 to the plasma membrane and led to a significant enhancement of water permeability in oocytes

- LP2, RWC3~OsPIP1;3, Plasma membrane receptor-like kinase leaf panicle 2 acts downstream of the DROUGHT AND SALT TOLERANCE transcription factor to regulate drought sensitivity in rice, In addition, LP2 was identified as a functional kinase localized to the plasma membrane and interacted with the drought-responsive aquaporin proteins OsPIP1; 1, OsPIP1; 3, and OsPIP2; 3.
- OsPIP2;2, RWC3~OsPIP1;3, Rice aquaporin OsPIP2;2 is a water-transporting facilitator in relevance to drought-tolerant responses, In concomitant tests of all OsPIPs, four genes (OsPIP1;3, OsPIP2;1, OsPIP2;2, and OsPIP2;4) were induced to express in leaves of rice plants following a physiological drought stress, while OsPIP2;2 was expressed to the highest level
- OsPIP2;2, RWC3~OsPIP1;3, Rice aquaporin OsPIP2;2 is a water-transporting facilitator in relevance to drought-tolerant responses, After de novo expression in tobacco protoplasts, OsPIP2;2 exceeded OsPIP1;3, OsPIP2;1, and OsPIP2;4 to support H2O transport across the plasma membranes
