XA21 is a receptor-like kinase protein in rice (Oryza sativa) that confers gene-for-gene resistance to specific races of the causal agent of bacterial blight disease, Xanthomonas oryzae pv oryzae. We identified XA21 binding protein 3 (XB3), an E3 ubiquitin ligase, as a substrate for the XA21 Ser and Thr kinase. The interaction between XB3 and the kinase domain of XA21 has been shown in yeast an...
WRKY proteins play important roles in transcriptional reprogramming in plants in response to various stresses including pathogen attack. In this study, we functionally characterized a rice WRKY gene, OsWRKY67, whose expression is upregulated against pathogen challenges. Activation of OsWRKY67 by T-DNA tagging significantly improved the resistance against two rice pathogens, Magnaporthe oryzae a...
Clustered regularly interspaced short palindromic repeat (CRISPR) is a bacterial immunity system that requires a perfect sequence match between the CRISPR cassette spacer and a protospacer in invading DNA for exclusion of foreign genetic elements. CRISPR cassettes are hypervariable, possibly reflecting different exposure of strains of the same species to foreign genetic elements. Here, we deter...
The rice (Oryza sativa) gene xa13 is a recessive resistance allele of Os-8N3, a member of the NODULIN3 (N3) gene family, located on rice chromosome 8. Os-8N3 is a susceptibility (S) gene for Xanthomonas oryzae pv oryzae, the causal agent of bacterial blight, and the recessive allele is defeated by strains of the pathogen producing any one of the type III effectors AvrXa7, PthXo2, or PthXo3, whi...
Potential of MoSM1, encoding for a cerato-platanin protein from Magnaporthe oryzae, in improvement of rice disease resistance was examined. Transient expression of MoSM1 in rice leaves initiated hypersensitive response and upregulated expression of defense genes. When transiently expressed in tobacco leaves, MoSM1 targeted to plasma membrane. The MoSM1-overexpressing (MoSM1-OE) transgenic rice ...
Crops carrying broad-spectrum resistance loci provide an effective strategy for controlling infectious disease because these loci typically confer resistance to diverse races of a pathogen or even multiple species of pathogens. Despite their importance, only a few crop broad-spectrum resistance loci have been reported. Here, we report the identification and characterization of the rice bsr-k1 (...
HDB disease is caused by Xanthomonas oryzae pv.oryzae, an important in rice plants. Recently, many organic compounds based antibacterial agents like chitosan are being developed. The potential raw materials for producing Black Soldier Fly (BSF) exuviae. At the development, was formulated with other ingredients such as kipahit leaves (Tithonia diversifolia) extract. This study aimed to synthesiz...
Xanthomonas oryzae pv. (X. oryzae) is a bacterial pathovar of rice diseases all over the world. Owing to emerging antibacterial resistance, phage therapies have gained significant attention treat various infections. Nevertheless, comprehensive research needed for their use as safe biocontrol agent. In this study, isolation and characterization novel Xoo-sp15, that infects X. was ascertained thr...
The Arabidopsis gene RESISTANCE TO POWDERY MILDEW8.1 (RPW8.1) confers resistance to virulent fungal and oomycete pathogens that cause powdery mildew and downy mildew, respectively. However, the underlying mechanism remains unclear. Here, we show that ectopic expression of RPW8.1 boosts pattern-triggered immunity (PTI) resulting in enhanced resistance against different pathogens in both Arabidop...
