A rice DELLA protein OsSLR1 positively regulates rice resistance to southern rice black-streaked dwarf virus infection.
Background: In the course of long-term confrontation with pathogens, plants have developed complex defense mechanisms to protect themselves from various pathogens. Previous studies have reported that the gibberellin (GA) signaling pathway negative regulator SLENDER RICE 1 (SLR1) in rice activates jasmonic acid (JA)-mediated broad-spectrum antiviral immunity, but the exploration regarding whether OsSLR1 exerts effects on alternative antiviral immune pathways remains limited.
Results: Here, we identified that OsSLR1 was significantly induced after virus infection and overexpression of OsSLR1 in rice enhance the resistance of rice to southern rice black-streaked dwarf virus (SRBSDV) in rice. Transcriptome analysis revealed that a total of 2,336 differentially expressed genes (DEGs) were detected upon overexpression of OsSLR1 in rice, including 1,607 upregulated genes and 729 downregulated genes. Gene ontology (GO) enrichment analysis and RT-qPCR analysis revealed that genes related to JA and reactive oxygen species (ROS) were significantly upregulated, while genes associated with abscisic acid (ABA) were significantly downregulated.
Conclusions: These results suggest that OsSLR1 positively regulates the antiviral immunity of rice by modulating multiple pathways.
