Summary: Introduction of different pest and disease resistance genes is crucial for successful cultivation of transgenic rice strains with broad-spectrum resistance. In this study, resistance rice lines with stacked resistance genes were produced and evaluated for their resistance to multiple pathogens. The findings suggest that stacking of rice resistance genes through molecular marker-assisted backcross breeding can confer broad spectrum and multiple resistance in differently genetic backgrounds.

Summary: Dimetindene maleate was effective in inducing systemic acquired resistance in rice plants, improving resistance to blast disease in both glasshouse and field conditions. The expression of certain genes (OsWRKY45 and OsNPR1) indicated the activation of the SA defense pathway, contributing to the enhanced resistance observed.

Summary: This study dissects the JA-dependent defense signaling in rice for both compatible and incompatible interactions by using JA-deficient mutants cpm2 and hebiba. The results demonstrate the pivotal role of JA in the basal immunity of rice in its resistance to the Rice Blast Fungus in both types of interactions.

Summary: This study utilized UHPLC/Q-TOF-MS to identify altered metabolites in transgenic rice infected with M. oryzae, revealing organic acids, organic oxygen compounds, lipids, and lipid-like molecules. The research showed that carbohydrate and amino acid metabolic pathways were involved in plant defense responses and resistance strengthening. The study also found that the identified metabolites could be utilized as an optimal marker for M.oryzae defense in rice.

Summary: Bacillus subtilis JN005 shows growth promotion and biocontrol efficacy against rice blast, improving germination and growth of rice seeds, enhancing defense enzyme activities in rice leaves, and reducing disease incidence by 79% and 76% in curative and preventive treatments, respectively. Additionally, field experiments demonstrate that spraying with JN005 suspension at 1x10(7) cfu/mL can effectively control rice blast and increase rice production yield.

Summary: The study identified two metalloproteinase enzymes, MoMca1 and MoMca2, in M. oryzae, which play significant roles in fungal growth and development, potentially regulating stress responses. The absence of these enzymes resulted in delays in fungal morphogenesis and insights into the mechanisms of M. oryzae pathogenicity.

Summary: This study investigates the diversity, composition, and assembly of microbial communities associated with the rhizosphere soils and endosphere of Piz-t-KJ201 and NPB-KJ201. The host genotype and inoculation pattern of M.oryzae played dominant roles in determining the microbial community assemblage. Metabolomics analysis revealed that some metabolites may influence changes in bacterial communities.

Summary: DNA methylation plays a role in regulating the expression of coding and non-coding regions in plants. A study using whole-genome bisulfite sequencing revealed temporal DNA methylation changes in rice after infection with Magnaporthe oryzae, showing a slight increase in global DNA methylation levels compared to Arabidopsis. Over 38,000 differentially methylated regions (DMRs) were identified, with hypermethylated DMRs dominating over hypomethylated DMRs, most of which were located in transposable element regions. Transcription of NBS-LRR family genes was affected by changes in DNA methylation, indicating the essential role of DNA methylation in rice response to M. oryzae infection.
