Abstract: Rice (Oryza sativa) is one of the most vital food crops globally, and its yield plays a crucial role in ensuring food security. However, various diseases affecting rice pose significant threats to this security. Among these, rice blast, bacterial blight, and sheath blight are the three predominant diseases impacting global rice production. Consequently, there is an urgent need to breed and cultivate rice varieties with broad-spectrum disease resistance. In recent years, substantial advancements have been made in understanding the regulatory mechanisms underlying disease resistance in rice. This paper reviews these mechanisms from multiple perspectives, including the plant’s intrinsic immune responses and the functional dynamics of resistance genes. Furthermore, it highlights pressing issues that require immediate attention to facilitate broad-spectrum disease-resistant breeding efforts for rice.

Key words: rice, disease resistance regulation mechanism, plant immune response
