“…Treatment with BVCs can improve crop quality and yields, including seed, fruit, tuber, biomass, essential oil, secondary metabolite and sugar yields. Bacillus subtilis GB03 volatiles and benzaldehyde increase biomass and essential oil contents in medicinal plants Codonopsis pilosula and Atractylodes lancea , respectively ( Wu et al , 2016 ; Zhou et al , 2016 ). The accumulation of sugars such as glucose, sucrose and starch is necessary for the quality of crops such as potato and sugar beet.…”

BackgroundBacterial volatile compounds (BVCs) are important mediators of beneficial plant–bacteria interactions. BVCs promote above-ground plant growth by stimulating photosynthesis and sugar accumulation and by modulating phytohormone signalling. These compounds also improve below-ground mineral uptake and modify root system architecture.ScopeWe review advances in our understanding of the mode of action and practical applications of BVCs since the discovery of BVC-mediated plant growth promotion in 2003. We also discuss unanswered questions about the identity of plant receptors, the effectiveness of combination of two or more BVCs on plant growth, and the potential side effects of these compounds for human and animal health.ConclusionBVCs have good potential for use as biostimulants and protectants to improve plant health. Further advances in the development of suitable technologies and preparing standards and guidelines will help in the application of BVCs in crop protection and health.

“…Historically, the ability of microbes to influence seed dormancy has not been well supported by data (Baskin and Baskin 2000), although many crop studies indicate that so-called plant growth-promoting bacteria can increase seed germination (Lucy et al 2004;Wu et al 2016). Many soil microbes are either pathogenic to seeds or they may protect seeds from pathogens.…”

Successful re-introduction of native species through ecological restoration requires understanding the complex process of seed germination. Soil microbes play an important role in promoting native establishment, and are often added to restoration sites during seed sowing. We tested the role of soil and lab-grown bacterial inoculants on germination timing and percent germination for nineteen species of plants commonly found in coastal California. Each species exhibited a different response to inoculant treatments, but overall time-to-germination was longer and percent germination was lower with soil inoculant compared to control or other treatments.The invasive species in our study had the highest percent germination of all species and germinated faster than all native shrubs. Germination timing was negatively correlated with percent germination and with seed weight. Our results suggest that lab grown inoculant and chemical treatment are effective at increasing germination in some native species, while soil inoculant is not. Given differences in germination timing between native and invasive species, restoration practitioners could consider using herbicide to treat areas seeded with native shrubs immediately following germination of invasive species without harming most natives, although germination timing and herbicides need further study in relation to microbial effects on seed germination.

Aim This study aimed to isolate Pseudobrickellia brasiliensis endophytic bacteria and evaluate the production of hydrolytic enzymes and antibiotics by these bacterial strains. The study also measured the antibacterial activity of P. brasiliensis. Methods and Results Thirteen endophytic bacteria strains were isolated from stem and leaf fragments of P. brasiliensis. Extracellular enzyme production by the isolated endophytic bacteria was evaluated in an agar plate‐based assay. The highest protease production was achieved by Bacillus subtilis P4 in alkaline medium. Antimicrobial activity of endophytic bacteria and P. brasiliensis extracts was investigated using microbroth dilution. An MIC value of 1000 μg ml−1 against Pseudomonas aeruginosa was found for B. subtilis P3, B. subtilis P5, Pseudomonas sp. P8 and Pseudomonas sp. P12. Leaf extract of P. brasiliensis showed the highest antibacterial activity against P. aeruginosa, with an MIC value of 0·781 mg ml−1. Conclusions Pseudobrickellia brasiliensis is a source of bacterial endophytes, which can produce antibacterial compounds and enzymes. This work also demonstrated the antibacterial potential of P. brasiliensis. Significance and Impact of the Study This is the first study that revealed the antibacterial activity of P. brasiliensis and bioactive metabolite production by P. brasiliensis endophytic bacteria.
