Natural extracts from Marchantia polymorpha against plant pathogens growth inhibition

Abstract

The health of plants, animals, and humans is seriously threatened by the production of toxins by bacteria and fungi. The aim of the current work is to find a dependable and eco-friendly microorganism biocontrol technique to alleviate this concern. In this work, the antibacterial abilities of Marchantia polymorpha (liverwort) extracts were examined. These extracts were collected from several altitudinal ranges in the Kumaon region in Uttarakhand province, India, in the western Himalayas. Using microbroth dilution methods, the minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC), and minimum fungicidal concentration (MFC) of the crude extracts were determined. The results demonstrated that the Marchantia polymorpha extracts exhibited potent antifungal activity against Macrophominaphaseolina, Fusarium oxysporum, Rhizoctonia solani, and Colletotrichum acutatum, as well as antibacterial activity against Pseudomonas syringae, Xanthomonas campestris, Staphylococcus aureus, and Bacillus subtilis. According to the study results, Marchantia polymorpha extracts may have applications as natural antimicrobials in a number of sectors, including medications, agriculture, and preserving food. The research we performed demonstrates the potential of liverwort extracts as a promising biocontrol agent against bacterial and fungal diseases and as an inducer of plant disease resistance, providing a safer and more environmentally friendly alternative to synthetic chemicals that is beneficial to both human health and the environment.
