Molecular genetic study reveals that OsWRKY13 overexpression enhances broad-spectrum disease resistance in rice, indicating its utility as a target for crop breeding.

Key Points

To determine the biological role and regulatory mechanism of the transcription factor OsWRKY13 in mediating rice immunity against bacterial and fungal pathogens.
Generated OsWRKY13-overexpressing rice lines and evaluated disease resistance to bacterial blight and fungal blast across seedling and adult growth stages.
Assessed plant fertility traits and quantified the transcript levels of genes involved in salicylic acid (SA) and jasmonic acid (JA) synthesis and signaling.
Investigated the promoter-binding activity of OsWRKY13 across target genes in SA and JA pathways following pathogen challenge.
Overexpression of OsWRKY13 conferred enhanced resistance to both bacterial blight and fungal blast at seedling and adult stages without adversely affecting plant fertility.
Transgenic expression led to the upregulation of SA biosynthesis and response genes, paired with the suppression of JA biosynthesis and response genes.
OsWRKY13 directly bound to the promoters of its own gene and at least three other genes within the SA and JA pathways, with binding activity modulated by pathogen infection.
