Gene Details:

• MSU gene ID: LOC_Os07g48630
• RAPdb gene ID: Os07g0685700
• Gene Symbol: OsEIL2
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• In rice, however, lack of MHZ6/OsEIL1 or OsEIL2 functions improves salt tolerance, whereas the overexpression lines exhibits salt hypersensitivity at seedling stage, indicating that MHZ6/OsEIL1 and OsEIL2 negatively regulate salt tolerance in rice.
• MHZ6/OsEIL1 and OsEIL2 Regulate Ethylene Response of Roots and Coleoptiles and Negatively Affect Salt Tolerance in Rice.
• Disruption of MHZ6/OsEIL1 caused ethylene insensitivity mainly in roots, whereas silencing of the closely-related OsEIL2 led to ethylene insensitivity mainly in coleoptiles of etiolated seedlings.
• Together, our study provides insights for functional diversification of MHZ6/OsEIL1 and OsEIL2 in ethylene response and finds a novel mode of ethylene-regulated salt stress response which could be helpful for engineering salt-tolerant crops.
• Furthermore, this negative regulation by MHZ6/OsEIL1 and OsEIL2 in salt tolerance is likely in part attributable to the direct regulation of OsHKT2;1 expression and Na+ uptake in roots.
• Transgenic plants of overexpressing OsEIL2 (OsEIL2-OX) show reduced tolerance to salt and drought stress compared with the controls.
• Taken together, these results revealed a new mechanism of OsEIL2 in abiotic stress responses.
• OsEIL2 is a nuclear-localized protein with transactivation activity in the C-terminus (amino acids 344-583) and can be induced by NaCl, polyethylene glycol (PEG), dark, and abscisic acid (ABA) treatment.
