Plant growth-promoting rhizobacteria (PGPR) have emerged as key players in sustainable agriculture due to their ability enhance plant growth, nutrient uptake, and disease resistance. A significant aspect of PGPR is the emission volatile organic compounds (VOCs), which serve signaling molecules that influence various physiological processes plants. This review article explores complex interactions between rhizobacterial VOCs soil health, focusing particularly on role cycling within agricultural ecosystems. By investigating mechanism production release by rhizobacteria, along with impacts properties microbial communities. We aim highlight potential (VOCs) for management. Additionally, we discuss promoting root enhancing processes. providing insights into these mechanisms, this offers tailored strategies exploring optimize availability, fertility, address environmental challenges agriculture. Exploring presents an opportunity establish resilient systems significantly global food security promote stewardship.

As salt stress has a negative impact on plant growth and crop yield, it is very important to identify develop any available biotechnology which can improve the tolerance of plants. Inoculation with plant-growth-promoting rhizobacteria (PGPR) proven environmentally friendly biotechnological resource for increasing plants potential in-field application. In addition, bacterial volatile organic compounds (mVOCs) are signal molecules that may have beneficial roles in soil-plant-microbiome ecosystem. We investigated effects mVOCs emitted by Pseudomona putida SJ46 SJ04 Mentha piperita grown under different levels NaCl evaluating their growth-promoting capacity increase effects. Furthermore, we evaluated control conditions biocontrol ability VOCs both these strains inhibit Alternaria alternata Sclerotium rolfsii. The did not lead an significant improvement peppermint growth.

Abstract Volatile organic compounds (VOCs) released by bacteria during proliferation have the potential to be used for rapid bacterial identification. VOCs change rapidy proliferation. However, current studies are mostly based on single-point or long-time-interval sampling, which may lead omission of metabolic information. In this study, we developed an integrated device culture-headspace injection-mass spectrometry detection. Using device, conducted high temporal resolution detection and analysis headspace from E. coli , P. aeruginosa S. aureus . The interval was 10 min. results showed that three caused elevation 30 ions in mass spectrum. These exhibited complex regular changes each bacterium. While changing trends some significantly different among bacteria. For a pattern initially increasing then decreasing, widening sampling can crucial information being missed. This important factor contributing differences previous studies. Therefore, method study more accurately trace trend provide technical support identification methods VOC

Endophytic nitrogen-fixing bacteria are versatile and widely distributed in plants. Numerous strains of endophytic used as biofertilizers to minimize the utilization chemical fertilizers, improve nutrient use efficiency, increase crop productivity, reduce environmental pollution. However, mechanism underlying interaction between plants is still unclear. So, present study was planned assess effects on sugarcane by analyzing changes physiological biochemical activities. In current study, Klebsiella variicola DX120E, an bacterium, inoculated varieties B8 ROC22 evaluate nitrogen carbon metabolism-related enzymatic activity biomass. Results showed that DX120E inoculation improved activities related gluconeogenesis metabolism increased plant's height, cane juice Brix, biomass, chlorophyll, soluble sugar content sugarcane. Metabolomics analysis revealed metabolome modules were highly enriched metabolic pathways strain-affected than uninoculated control.

However, chemical characteristics of aromatic substances in are still mostly unknown. This study aimed identify key volatile aroma compounds biosynthetic pathways possibly involved their formation Thai varieties, thus leading search for genetic markers breeding colored better properties. Twenty-three four categories: white, black, non-aromatic red, were investigated (n=10 per variety). Seed husks removed before analysis aromas by static headspace gas chromatography-mass spectrometry. Untargeted metabolomics approach was used discover rice. Forty-eight detected. Thirty-eight 48 significantly differed among groups at p<0.05, 28 which p<0.0001, black red containing much lower content most constituents than Focusing on samples appeared contain high level both compound aldehydes (3-methylbutanal, 2-methylbutanal, 2-methylpropanal, pentanal, hexanal) alcohols (butane-2,3-diol, pentan-1-ol, hexan-1-ol). Biosynthetically, these distinctive black-rice proposed be formed from metabolic degradation branched-chain amino acids (L-leucine, L-isoleucine L-valine) polyunsaturated fatty (linoleic acid α-linolenic acid), involving aminotransferases keto-acid decarboxylases 9-lipoxygonases 13-lipoxygeases, respectively.
