Meloidogyne graminicola is a significant pathogen of rice (Oryza sativa L) . The serious epidemic of M. graminicola is a significant global concern, as it significantly impacts the safe production of rice. Understanding the pathogenesis of M. graminicola and the resistance mechanisms of rice to it has been a key research focus in recent years, as it provides the foundation for developing new strategies for the prevention and control of rice root-knot nematodes. In recent years, with the rapid development of molecular biology and genomics sequencing technologies, the genome of M. graminicola has been successfully sequenced, and the multiple effectors have been explored. Additionally, the resistance of rice root knot nematodes was analyzed, and multiple quantitative trait loci (QTLs) were identified within its chromosomes, and the first rice gene, MG1, resistant to root knot nematodes has been successfully cloned. Furthermore, rice possesses the capability to modulate hormonal signaling cascades, including those involving jasmonic acid and ethylene. This activation initiates a regulatory cascade, enabling the rice plant to effectively counter the nematode's pathogenicity and parasitism. These significant research findings provide scientific evidence, deepening our understanding of M. graminicola's pathogenic mechanism and rice's resistance mechanism against root-knot nematodes. This paper presents a review of recent research progress on the pathogenic mechanisms of M. graminicola and the response mechanisms of rice and highlights potential future directions in the interaction between M. graminicola and its host.
