    • 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

    • OsEBF1, OsEIL2, Phytochrome B mediates dim-light-reduced insect resistance by promoting the ethylene pathway in rice., In addition, we found that nuclear OsphyB stabilizes Ethylene Insensitive Like2 (OsEIL2) by competitively interacting with EIN3 Binding F-Box Protein (OsEBF1) to enhance ET signaling in rice, which contrasts with previous findings that phyB blocks ET signaling by facilitating Ethylene Insensitive3 (EIN3) degradation in other plant species
