Xanthomonas oryzae pv. oryzae is a bacterial pathogen that gives rise to diseases in rice all over the world. A bacteriophage infecting this bacterium was isolated from rice fields in China. Here, we report the complete genome sequence of this phage, which has a linear dsDNA genome of 309,023 bp and a G + C content of 42.43%. It contains 401 open reading frames and encodes 28 tRNAs. It belongs to the family Myoviridae and has a broad host range, making it a possible candidate for phage therapy.

In the intricate molecular warfare between plants and pathogens, bacteria deploy sophisticated strategies to subvert host defenses. Xanthomonas oryzae pathogens, which cause devastating bacterial blight (BB) and bacterial leaf streak (BLS) in rice, utilize transcription activator-like effectors (TALEs) to manipulate host gene expression. Secreted by the type III secretion system and translocated by the type III translocon into host cells, TALEs directly bind specific DNA sequences (effector-binding elements, EBEs) in the 5'-terminal untranslated regions (UTRs) or within the promoter regions of host genes to activate transcription of these genes, including SWEETs sugar transporters and negative regulators of plant immunity (Xue et al.

Background: Global crop yields suffer severe losses due to pathogenic infections, and the drug resistance of traditional fungicides has become a prominent issue. Developing new fungicides with high efficiency, environmental friendliness, and low toxicity has become an important task in agricultural plant protection, which also promotes natural product-derived green pesticides to become a research hotspot.
Results: 30 formononetin derivatives incorporating isopropanolamine moieties were rationally designed and synthesized as potential plant disease control agents.

Rice blast is one of the main diseases of rice, causing severe economic losses to agricultural production; thus, the search for blast resistance is a top priority for rice breeding. When challenged by the blast causal fungus the expression level of gene in rice cultivar Nipponbar was found to increase significantly. Such an induction was also found in a different genetic material, cultivar Shufanggaonuo, indicating that plays an important role in blast disease response.

Bacterial leaf blight (BLB) is a major threat to global rice production, leading to yield losses of up to 40% despite extensive disease management practices. The persistence of pv. (Xoo) necessitates an eco-friendly and effective alternative to synthetic pesticides.

Background: Rumex nervosus Vahl is a phenomenal plant from Arabian Peninsula and East African areas. It potentially contains massive therapeutic phytochemicals, including Omeprazole, sitosterols, fatty acids, flavonoids and carotenes. Omepazole (a commercial drug) is used to treat stomach ulcers, gastroesophageal reflux and cardiac disorders.
