Overexpression of OsHAK5 potassium transporter enhances virus resistance in rice (Oryza sativa).

ABSTRACT: Intracellular potassium (K⁺ ) transported by plants under the action of a number of transport proteins is crucial for plant survival under distinct abiotic and biotic stresses. A correlation between K⁺ status and disease incidence has been found in many studies, but the roles of K⁺ in regulating disease resistance to viral diseases remain elusive. Here, we report that HIGH-AFFINITY K⁺ TRANSPORTER 5 (OsHAK5) regulates the infection of rice grassy stunt virus (RGSV), a negative-sense single-stranded bunyavirus, in rice (Oryza sativa). We found the K⁺ content in rice plants was significantly inhibited on RGSV infection. Meanwhile, a dramatic induction of OsHAK5 transcripts was observed in RGSV-infected rice plants and in rice plants with
