Bacterial leaf streak disease caused by Xanthomonas oryzae pv. Oryzicola (Xoc) is a serious threat to rice production worldwide. Like most bacterial phytopathogens, Xoc also contains multiple regulators involved in the complex regulatory networks to ensure its virulence. In this study, we found two genes, FE36_09860 and FE36_06255, through quantita...

Strawberry (Fragaria × ananassa Duch), known as the “queen of fruits,” is an economically important crop widely cultivated globally and known for its unique taste and nutritional value. In China, Yunnan Province (25° 3′ 0″ N, 101° 52′ 0″ E) is famous for its unique environment and is favorable for the development of the strawberry industry. During...

The present study aimed to evaluate transcriptional activator-like effector (TALE) genes in 86 Xanthomonas oryzae pv. oryzicola strains collected from 8 rice-growing regions in Yunnan, and to examine the relationship between TALE genotypes and virulence in 6 differential rice lines. Besides, the geographical areas, distribution of these genotypes w...
Article
Bacterial leaf streak caused by Xanthomonas oryzae pv. oryzicola (Xoc) is one of the most destructive diseases affecting rice production worldwide. In this study, we extracted and purified phenazine substances from the secondary metabolites of Lysobacter antibioticus 13-6. The bacteriostatic mechanism of phenazine substances against Xoc was investi...
Article
Bacterial leaf streak (BLS) caused by Xanthomonas oryzae pv. oryzicola (Xoc), impacts the production of rice. However, several rice cultivars displayed resistance to Xoc in the field, but scarce information is available about the role of endophytic microbiota in disease resistance. In the present study, the endophytic bacterial communities of resis...
Article
Bacterial leaf streak caused by Xanthomonas oryzae pv. oryzicola (Xoc) is a devastating disease of rice worldwide, including China. The second messenger c-di-GMP plays an important role in the transduction of intercellular signals. However, little is known about the function of EAL domain protein in c-di-GMP that regulates the virulence in Xoc. In...

... In our previous study, B. velezensis CFS treatment might have led to an energy shortage in P. olsonii, which accelerated alternative carbon metabolism, and the decreased energy status further disturbed cell homeostasis . Similarly, other antifungal agents have also been reported to affect energy metabolism and reduce the pathogenicity of pathogens (Chen et al., 2020;Owens and Doyle, 2021;Liu et al., 2022;Wijnants et al., 2022). Thus, damage to the cell membrane system and disturbance of energy metabolism might ultimately accelerate cell death, which partly explains the antifungal effects of B. velezensis CFS treatment. ...
... Rice stands as an essential food crop, serving as the staple food for over half of the world's population (Kong et al., 2020;Yang et al., 2021). Despite utilizing only 11% of the world's cropland, it contributes to 21% of global calorie consumption (Syahri & Somantri, 2023). ...
... 1,2 As a critical staple food crop feeding more than 3.5 billion people worldwide, rice production deeply suffers from plant pathogens at all stages. 3 For example, rice bacterial leaf streak (BLS) caused by the pathogen Xanthomonas oryzae pv. oryzicola (Xoc) is a devastating disease for rice. ...
