Bacterial endophytes are a crucial component of the phytomicrobiome, playing an essential role in agriculture and industries. Endophytes are a rich source of bioactive compounds, serving as natural antibiotics that can be effective in combating antibiotic resistance in pathogens. These bacteria interact with host plants through various processes such as quorum sensing, chemotaxis, antibiosis, and enzymatic activity. The current paper focuses on how plants benefit extensively from endophytic bacteria and their symbiotic relationship in which the microbes enhance plant growth, nitrogen fixation, increase nutrient uptake, improve defense mechanisms, and act as antimicrobial agents against pathogens. Moreover, it highlights some of the bioactive compounds produced by endophytes.

Background: Clubroot, caused by Plasmodiophora brassicae, significantly impacts cruciferous crop production worldwide. Biocontrol is an environmentally friendly and promising approach for clubroot management. Endophytic bacteria are known for their ability to promote plant growth and induce resistance against plant diseases.

Herein, we report the isolation and characterization of an endophytic bacterium associated with the Berberis aristata roots to uncover bioactive compounds, particularly Antimicrobials, using submerged culture. The bacterial isolate was identified via 16S rDNA sequence analysis and characterized using morphological, microscopic, and biochemical techniques. It was identified as Bacillus toyonensis strain BAR1, a motile, gram-positive, halotolerant bacterium capable of producing yellow pigments.

Citrus Huanglongbing (HLB), caused by "Candidatus Liberibacter asiaticus" (CLas), is a destructive disease threatening global citrus industry. Although citrus cultivars differ in HLB sensitivity, how infection alters endophytic bacterial communities in cultivars with contrasting susceptibility remains unclear. Here, we compared endophytic microbiome shifts in leaf and root tissue of HLB-susceptible Shatangju mandarin (C.

The taxonomic status of two bacterial strains, KW56 and 2063, isolated from root nodules of (Spanish broom), was investigated using a polyphasic approach. Both isolates belong to the genus , yet exhibit significant genotypic and phenotypic differences from all currently described species. Whole-genome comparisons revealed that strain KW56 is most closely related to PETP 02, while strain 2063 is related to strains STM 196 and 29-15.
