  • Key message
    • A significant number of genes involved in lipid metabolism and protection against oxidative stress appear to be up-regulated by OsCPK4 in roots of overexpressor plants
    • Taken together, our data show that OsCPK4 functions as a positive regulator of the salt and drought stress responses in rice via the protection of cellular membranes from stress-induced oxidative damage
    • Meanwhile, OsCPK4 overexpression has no effect on the expression of well-characterized abiotic stress-associated transcriptional regulatory networks (i
    • Overexpression of OsCPK4 in rice plants significantly enhances tolerance to salt and drought stress
    • Compared with control plants, OsCPK4 overexpressor plants exhibit stronger water-holding capability and reduced levels of membrane lipid peroxidation and electrolyte leakage under drought or salt stress conditions
    • Moreover, a plasma membrane localization of OsCPK4 was observed by transient expression assays of green fluorescent protein-tagged OsCPK4 in onion (Allium cepa) epidermal cells
    • Here, we report that OsCPK4 expression is induced by high salinity, drought, and the phytohormone abscisic acid
    • Also, salt-treated OsCPK4 seedlings accumulate less Na(+) in their roots
    • Enhancing blast disease resistance by overexpression of the calcium-dependent protein kinase OsCPK4 in rice.
    • It shows that overexpression of OsCPK4 gene in rice plants enhances resistance to blast disease by preventing fungal penetration
    • Altogether, our findings indicate that OsCPK4 is a potential molecular target to improve not only abiotic stress tolerance, but also blast disease resistance of rice crops
    • Given that OsCPK4 overexpression was known to confer also salt and drought tolerance in rice, the results reported in this article demonstrate that OsCPK4 acts as a convergence component that positively modulates both biotic and abiotic signalling pathways
    • OsCPK4 overexpression leads also to constitutive increased content of the glycosylated salicylic acid hormone in leaves without compromising rice yield
    • In this work, the isoform OsCPK4 of the rice calcium-dependent protein kinase family is reported as a regulator of rice immunity to blast fungal infection
    • The constitutive accumulation of OsCPK4 protein prepares rice plants for a rapid and potentiated defence response, including the production of reactive oxygen species, callose deposition and defence gene expression
