چکیده

The colonization of plant growth-promoting rhizobacteria (PGPR) along roots in turn facilitates their ability to promote growth and health. In this study, we found that Bacillus subtilis strain WM13-24 from the rhizosphere Haloxylon ammodendron was able both Arabidopsis its host plant. Furthermore, volatile organic compounds (VOCs) could by stimulating lateral root formation hair growth. However, molecular mechanism underlying WM13-24-stimulated development is still unknown. a series mutants defective specific hormone signaling pathways were used as materials preliminarily study effect VOCs released on through genetic pharmacological methods. identified solid-phase microextraction gas chromatography-mass spectrometry (SPME–GC–MS). plant, H. ammodendron. Auxin transport played crucial role changes architectures Arabidopsis. SPME–GC–MS analysis revealed produces various classes compounds. We further showed 2,3-butanediol benzyl alcohol active promoting responses plants two concentration dependent. All these results suggested emitted B. improves depending auxin signaling.

Induced Salt Tolerance of Perennial Ryegrass by a Novel Bacterium Strain from the Rhizosphere of a Desert Shrub Haloxylon ammodendron

Drought and soil salinity reduce agricultural output worldwide. Plant-growth-promoting rhizobacteria (PGPR) can enhance plant growth and augment plant tolerance to biotic and abiotic stresses. Haloxylon ammodendron, a C4 perennial succulent xerohalophyte shrub with excellent drought and salt tolerance, is naturally distributed in the desert area of northwest China. In our previous work, a bacte...

Impact of a Bacterial Volatile 2,3-Butanediol on Bacillus subtilis Rhizosphere Robustness

Volatile compounds, such as short chain alcohols, acetoin, and 2,3-butanediol, produced by certain strains of root-associated bacteria (rhizobacteria) elicit induced systemic resistance in plants. The effects of bacterial volatile compounds (BVCs) on plant and fungal growth have been extensively studied; however, the impact of bacterial BVCs on bacterial growth remains poorly understood. In thi...

Characterization of Bacillus subtilis HC8, a novel plant‐beneficial endophytic strain from giant hogweed

Thirty endophytic bacteria were isolated from various plant species growing near Saint-Petersburg, Russia. Based on a screening for various traits, including plant-beneficial properties and DNA fragment patterns, potential siblings were removed. The remaining isolates were taxonomically identified using 16S rDNA sequences and potential human and plant pathogens were removed. The remaining strai...
