OsEL2 Regulates Rice Cold Tolerance by MAPK Signaling Pathway and Ethylene Signaling Pathway.

ABSTRACT: Low temperature stress represents a significant abiotic stress factor affecting rice yields. While the structure and some of the functions of cell cycle protein-dependent protein kinase inhibitor (CKI) family proteins have been the subject of study, their relevance to cold tolerance in rice has been less investigated. In this study, we cloned OsEL2 (LOC_Os03g01740) and constructed anti-expression lines of this gene. The resulting lines exhibited significant cold sensitivity and displayed greater oxidative damage than wild type Nippobare (Nip). However, the activities of antioxidant enzymes, such as catalase (CAT), were significantly elevated in OsEL2-AX plants in comparison to Nip following exposure to 4 °C stress. RNA sequencing revealed the presence of 18,822 differe
