Spinach is one of the most nutritious green-leaf vegetables. In the spinach production, diseases cause a significant loss in both yield and quality. Improving disease resistance is one of the major challenges in spinach breeding. Arabidopsis nucleoporin CONSTITUTIVE EXPRESSER OF PATHOGENESIS-RELATED GENES 5 (CPR5) functions as a negative regulator of plant cell death and immunity ascpr5mutant exhibits spontaneous cell death and heightened immunity. In addition, CPR5 play a role in trichome development as the majority ofcpr5mutant trichomes are branchless whereas wild type trichomes are often three-branched. In the spinach genome, we identified a homolog of Arabidopsis CPR5, referred to asSpinacia oleraceaCPR5 (SoCPR5). To investigate the function of SoCPR5, we introducedSoCPR5into Arabidopsiscpr5mutant. Our data showed that both spontaneous cell death and heightened immunity were suppressed in theSoCPR5-transgeniccpr5mutants, verifying that SoCPR5 functions as its Arabidopsis counterpart in plant cell death and immunity. SoCPR5 also fully restored wild type trichome phenotype of thecpr5mutant. Our study therefore indicates that the function of SoCPR5 is conserved between plant species and SoCPR5 can be applied for genetic manipulation of plant immunity in spinach.
