Every year, invasive pathogens cause significant damage to crops. Thus, identifying genes conferring broad-spectrum resistance to invading pathogens is critical for plant breeding. We previously demonstrated that OsWRKY114 contributes to rice ( L.) immunity against the bacterial pathovar pv. (). However, it is not known whether OsWRKY114 is involved in defense responses to other pathogens. In this study, we revealed that OsWRKY114 enhances innate immunity in rice against the fungal pathogen , which is the causal agent of bakanae disease. Transcript levels of various gibberellin-related genes that are required for plant susceptibility to were reduced in rice plants overexpressing . Analysis of disease symptoms revealed increased innate immunity against in -overexpressing rice plants. Moreover, the expression levels of genes, which encode negative regulators of jasmonic acid signaling that confer immunity against , were reduced in -overexpressing rice plants. These results indicate that OsWRKY114 confers broad-spectrum resistance not only to but also to . Our findings provide a basis for developing strategies to mitigate pathogen attack and improve crop resilience to biotic stress.

The Cas12j-8 nuclease, derived from the type V CRISPR system, is approximately half the size of Cas9 and recognizes a 5'-TTN-3' protospacer adjacent motif sequence, thus potentially having broad application in genome editing for crop improvement. However, its editing efficiency remains low in plants. In this study, we rationally engineered both the crRNA and the Cas12j-8 nuclease.

Rice salt tolerance is highly anticipated to meet global demand in response to decreasing farmland and soil salinization. Therefore, dissecting the genetic loci controlling salt tolerance in rice for improving productivity is of utmost importance. Here, we evaluated six salt-tolerance-related traits of a biparental mapping population comprising 280 F2 rice individuals (Oryza sativa L.

Maintaining a stable basal level of salicylic acid (SA) is crucial for plant growth, development, and stress response, though basal levels of SA vary significantly among plant species. However, the molecular mechanisms by which basal SA regulates plant growth and stress response remain to be elucidated. In this study, we performed a genetic screen to identify suppressors of the root growth defect in Osaim1, a rice mutant deficient in basal SA biosynthesis.

Rice yield strongly depends on panicle size and architecture but the genetics underlying these traits and their coordination with environmental cues through various signaling pathways have remained elusive. A genome-wide association study (GWAS) was performed to pinpoint the underlying genetic determinants for rice panicle architecture by analyzing 20 panicle-related traits using a data set consisting of 44,100 SNPs. We defined QTL windows around significant SNPs by the rate of LD decay for each chromosome and used these windows to identify putative candidate genes associated with the trait.

Antibiotic resistance genes (ARGs) rebounding during composting cooling phase is a critical bottleneck in composting technology that increased ARGs dissemination and application risk of compost products. In this study, mature compost (MR) was used as a substitute for rice husk (RH) to mitigate the rebound of ARGs and mobile genetic elements (MGEs) during the cooling phase of sewage sludge composting, and the relationship among ARGs, MGEs, bacterial community and environmental factors was investigated to explore the key factor influencing ARGs rebound. The results showed that aadD, blaCTX-M02, ermF, ermB, tetX and vanHB significantly increased 4.
