Summary: Orphan genes are commonly found in genomes, but their functions are largely unknown. In this study, a defense-related orphan gene Xio1 was identified and found to play an important role in rice's defense mechanism, providing a new resource for crop breeding.

Summary: The phytohormone abscisic acid (ABA) regulates the immune response of rice to Xanthomonas oryzae pv. oryzae (Xoo). This study identified OsWRKY114 as a negative regulator of ABA, reducing the susceptibility of rice to Xoo infection and affecting the expression of ABA-associated genes.

Summary: This study found that ethylicin (ET) inhibited the proliferation of Xanthomonas oryzae pv. oryzae (Xoo) by increasing the content of defense enzymes and chlorophyll in rice. It was also discovered that ET activated the abscisic acid (ABA) signal pathway and made the protein kinase OsCPK24 more active, enhancing the resistance of rice to Xoo.

Summary: Through a genome-wide association study approach, this research identified a complex genetic interaction system between rice and the bacterial pathogen Xanthomonas oryzae pv. oryzae, characterized by genome-wide interactions between rice quantitative resistance genes and Xoo virulence genes. This genetic system may lead to dynamic coevolutionary consequences during the reciprocal adaptation of rice and Xoo.

Summary: This study aimed to investigate the co-evolution of bacterial pathogens with their host plants as well as with their bacterial viruses. Through experiments, several genes associated with both phage sensitivity and host pathogenicity were identified, and three genes were found to play a key role in bacterial virulence and phage resistance.

Summary: Bacterial leaf blight (BLB) and bacterial leaf streak (BLS), caused by Xanthomonas oryzae pv. oryzae (Xoo) and Xanthomonas oryzae pv. oryzicola (Xoc), can be effectively controlled using lytic broad-spectrum phages pXoo2106 and pXoo2107. These phages inhibit the growth of Xoo and Xoc and have strong biocontrol potential against BLB and BLS in field applications.

Summary: The overexpression of OsNPR1 enhances rice resistance to Xanthomonas oryzae pv. oryzae (X-oo) by bidirectionally regulating gene expression in rice and X-oo. In X-oo-infected OsNPR1-OE plants, rice genes involved in cell wall biosynthesis, SA signaling pathways, and PR genes are upregulated, while X-oo genes involved in energy metabolism, oxidative phosphorylation, biosynthesis, and transportation are repressed. The downregulation of virulence genes, including components of type III and other secretion systems, is observed in X-oo due to OsNPR1 overexpression.

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.

Summary: In this study, combinations of four BB resistance genes were pyramided into populations derived from a widely planted Indonesian rice variety crossed with an IRBB60 resistant variety. Promising recombinants with high yield potential and broad spectrum resistance were identified through marker-assisted selection. The developed BB-resistant RILs have the potential to be further developed for cultivation or as sources of BB resistance for varietal improvement in other rice lines.

Summary: Bacterial leaf blight (BB) of rice, caused by Xanthomonas oryzae pv. oryzae (Xoo), poses a threat to global food security and the livelihood of small-scale rice producers. Despite robust global rice trade, Xoo strains from different regions show complete continental segregation. Unprecedented BB outbreaks were discovered in Tanzania, caused by Xoo strains carrying Asian-type TAL effectors and iTAL effectors, unlike endemic African Xoo strains. In order to protect African rice production from this emerging threat, a hybrid CRISPR-Cas9/Cpf1 system was developed to edit TALe-binding elements in SWEET promoters. The edited lines displayed broad-spectrum resistance against Asian and African Xoo strains.

Summary: In this study, a novel dominant gene Xa39, which confers broad-spectrum resistance for bacterial blight (BB), was successfully introgressed into restorer lines of rice through marker-assisted introgression breeding method. The newly developed BB-resistant restorers and their hybrids with sterile lines exhibited similar resistance levels as the resistant donor. This study provides important reference information for utilizing the Xa39 gene in rice breeding program.

Summary: Xanthomonas oryzae pv. oryzae (Xoo) is a plant pathogen that causes bacterial blight in rice. The study shows that early response genes of Xoo are related to cell motility, inorganic ion transport, and effectors. The comparison of transcriptome and proteome reveals differences in transcriptional and translational expression peaks in many genes during Xoo pathogenesis.

Summary: This study investigated the influence of DNA (de)methylases on DNA methylation and gene expression of Arabidopsis ET pathway genes. The results showed that CG methylation within gene body regions of some genes is regulated by MET1 and other (de)methylases, and that CG methylation is essential for the ET pathway in Arabidopsis.
