Summary

Syringolin A from pathogens activates rice immunity by upregulating OsNAC78 and Pir7b gene expression, leading to blast resistance. This pathway involves reactive oxygen species (ROS) accumulation.

Area of Science:

Plant Pathology
Molecular Plant-Microbe Interactions
Plant Immunity

Background:

Non-host pathogens induce broad-spectrum plant resistance.
Syringolin A activates the defense gene Pir7b in rice, but the mechanism is unclear.

Purpose of the Study:

Investigate the role of OsNAC78 in the plant immune pathway.
Elucidate the mechanism of syringolin A-induced rice immunity.

Main Methods:

Transgenic rice lines (OsNAC78 overexpression/knockout, Pir7b overexpression/knockout) were created.
Plants were inoculated with Magnaporthe oryzae.
Promoter activity and gene expression were analyzed under syringolin A treatment.

Main Results:

OsNAC78 acts as a positive regulator of blast resistance.
Pir7b confers blast resistance.
Syringolin A activates the OsNAC78-Pir7b module, enhancing promoter activity and inducing Pir7b transcription.
OsNAC78 is essential for Pir7b expression and syringolin A-induced immunity.
Reactive oxygen species (ROS) accumulation is involved in the induced resistance.

Conclusions:

Syringolin A induces rice immunity via the OsNAC78-Pir7b pathway.
OsNAC78 regulates Pir7b expression, triggering blast resistance.
This study reveals a non-host pathogen-induced immune signaling mechanism in rice.
