“…As expected, there is a strong correlation between the severity of the disease and our ability to recover isolates, even if we managed to recover a few isolates from asymptomatic panicles, as done in a previous study from China (Zhu et al 2008). Bacteria invaded the panicles and the grain and increased in density during infection (Pedraza et al 2018), which clearly explains our success in recovering more easily isolates from diseased panicles. We were, however, unable to detect any correlation between the genotype of the isolates and the health status of the panicle, although our sampling was not strictly adapted to detect such a link.…”

Bulkholderia glumae is responsible for the panicle blight disease of rice. This disease is present worldwide and can result in significant drop in yields. In order to estimate the genetic diversity of the bacterial strains present in a rice paddy field in Colombia, we sampled 109 strains from infected panicles. In order to detect fine genetic relationships among related haplotypes, and to overcome a very low nucleotide diversity detected in previous studies, we designed primers to amplify and sequence several highly variable minisatellite loci, or Variable Number Tandem Repeats, as well as part of the Toxoflavin toxA gene, in all strains. Results show that (i) the toxA nucleotide diversity defined four lineages and was similar to that detected in several fields in Japan, (ii) data suggest that B. glumae has spread from Asia to America without major loss of genetic diversity, (iii) five VNTR loci discriminated the strains within the field revealing single and multi-infections of the rice panicles with a wide distribution of the haplotypes among the different plots. Even though disease levels vary considerably from year to year, the bacterial genetic diversity is maintained within a field. We do not detect any geographical structuring within the field, nor any effect of the rice cultivar on the observed diversity. The consequences on the origin and evolution of the bacteria are discussed.

“…The rice BPB disease was first reported in Japan; however, it is currently spread in most rice-producing countries, including China, the United States, Malaysia, Sri Lanka, Thailand, South Korea, and Panama [ 5 , 6 ]. The BPB has severely reduced yields of infected rice fields as it causes severe damage, e.g., floret sterility, grain abortion, and milling quality reduction [ 7 , 8 , 9 ].…”

Burkholderia glumae and B. gladioli are seed-borne rice pathogens that cause bacterial panicle blight (BPB) disease, resulting in huge rice yield losses worldwide. However, the excessive use of chemical pesticides in agriculture has led to an increase in environmental toxicity. Microbe-mediated nanoparticles (NPs) have recently gained significant attention owing to their promising application in plant disease control. In the current study, we biologically synthesize zinc oxide nanoparticles (ZnONPs) from a native Bacillus cereus RNT6 strain, which was taxonomically identified using 16S rRNA gene analysis. The biosynthesis of ZnONPs in the reaction mixture was confirmed by using UV–Vis spectroscopy. Moreover, XRD, FTIR, SEM-EDS, and TEM analysis revealed the functional groups, crystalline nature, and spherical shape of ZnONPs with sizes ranging from 21 to 35 nm, respectively. Biogenic ZnONPs showed significant antibacterial activity at 50 µg mL−1 against B. glumae and B. gladioli with a 2.83 cm and 2.18 cm zone of inhibition, respectively, while cell numbers (measured by OD600) of the two pathogens in broth culture were reduced by 71.2% and 68.1%, respectively. The ultrastructure studies revealed the morphological damage in ZnONPs-treated B. glumae and B. gladioli cells as compared to the corresponding control. The results of this study revealed that ZnONPs could be considered as promising nanopesticides to control BPB disease in rice.

“…B. glumae , the causal agent of bacterial grain rot and seedling rot of rice, was isolated from hot and high relative humid areas [ 99 ]. B. glumae was first reported in Japan, but later it was distributed in different countries producing rice such as: Japan, Thailand, Vietnam, South Korea, Malaysia, Philippines, Sri Lanka, United States, Panama, Nicaragua, Costa Rica, and Colombia [ 100 ]. The incidence of B. glumae has been increased recently due to climate changes, as well as the deficiency of appropriate management and biocontrol strategies [ 100 ].…”

Burkholderia is an important bacterial species which has different beneficial effects, such as promoting the plant growth, including rhizosphere competence for the secretion of allelochemicals, production of antibiotics, and siderophores. In addition, most of Burkholderia species have demonstrated promising biocontrol action against different phytopathogens for diverse crops. In particular, Burkholderia demonstrates significant biotechnological potential as a source of novel antibiotics and bioactive secondary metabolites. The current review is concerned with Burkholderia spp. covering the following aspects: discovering, classification, distribution, plant growth promoting effect, and antimicrobial activity of different species of Burkholderia, shedding light on the most important secondary metabolites, their pathogenic effects, and biochemical characterization of some important species of Burkholderia, such as B. cepacia, B. andropogonis, B. plantarii, B. rhizoxinica, B. glumae, B. caryophylli and B. gladioli.
