| Study Title | Endophytic bacteria are key players in the modulation of the secondary metabolome of Lithospermum officinale L. |
| Study Summary | Endophytic bacteria influence plant growth and development and therefore are an attractive resource for applications in agriculture. However, little is known about the impact of these microorganisms on secondary metabolite (SM) production by medicinal plants. Here we assessed, for the first time, the effects of root endophytic bacteria on the modulation of SMs in the medicinal plant Lithospermum officinale (Boraginaceae family), with a focus on the naphthoquinones alkannin/shikonin (A/S). The study was conducted using a newly developed in vitro system as well as in the greenhouse. Targeted and non-targeted metabolomics approaches were used and supported by expression analysis of the gene PGT, encoding a key enzyme in the A/S biosynthesis pathway. Three bacterial strains, Chitinophaga sp. R-73072, Xanthomonas sp. R-73098 and Pseudomonas sp. R-71838 induced a significant increase of diverse SMs, including A/S, in L. officinale in both systems, demonstrating the strength of our approach for screening A/S derivative-inducing bacteria. Our results highlight the impact of root-endophytic bacteria on secondary metabolism in plants and indicate that production of A/S derivatives in planta likely involves cross-modulation of different metabolic pathways that can be manipulated by bacterial endophytes. |

Sample Preparation:
| Sampleprep ID: | SP002150 |
| Sampleprep Summary: | The lyophilised roots were ground to a fine powder using a ball mill (Fritsch Pulverisette 0, Germany). For each powdered sample, a subsample of 35 mg was placed into microcentrifuge tubes for SMs extraction with 1.5 ml of methanol (LC-MS grade, Honeywell Riedel de Haën, USA) in an ultrasound bath at 10% power for three hours (Bandelin Sonorex Digital 10P, Berlin, Germany) followed by centrifugation for 10 minutes at 12500 rpm (Hermle Z 216 MK, Wehingen, Germany). The supernatants were collected and subjected to Ultra-High-Performance Liquid Chromatography-High Resolution Mass Spectrometry (UHPLC-HRMS) analysis, after filtering with 0.22 μm polytetrafluorethylene (PTFE) filters. |
