Abstract

Rhamnolipids are glycolipid biosurfactants naturally produced by Pseudomonas and Burkholderia bacteria, well-known for their surface-active properties and eco-friendly advantages. Indeed, these compounds efficiently reduce the surface and interface tensions, possess potent biological activities against pathogens, and display low toxicity. Rhamnolipids thus hold significant promise for various industrial applications, including agriculture, which is in need of a transition to greener and more sustainable practices by reducing synthetic inputs. This review describes the knowledge about the antimicrobial properties of rhamnolipids against different phytopathogens, mainly fungal species, as well as their ability to trigger plant defense mechanisms and phytoprotection efficacy in different species. The recent literature investigating rhamnolipids as potential plant biostimulation agents, thanks to their abilities to improve soil health and plant tolerance to abiotic stresses, is also addressed. Finally, the prospect of rhamnolipids as a biopesticide and their overall contribution to sustainable agricultural practices is discussed.

期刊介绍： The journal Plant Stress deals with plant (or other photoautotrophs, such as algae, cyanobacteria and lichens) responses to abiotic and biotic stress factors that can result in limited growth and productivity. Such responses can be analyzed and described at a physiological, biochemical and molecular level. Experimental approaches/technologies aiming to improve growth and productivity with a potential for downstream validation under stress conditions will also be considered. Both fundamental and applied research manuscripts are welcome, provided that clear mechanistic hypotheses are made and descriptive approaches are avoided. In addition, high-quality review articles will also be considered, provided they follow a critical approach and stimulate thought for future research avenues. Plant Stress welcomes high-quality manuscripts related (but not limited) to interactions between plants and: Lack of water (drought) and excess (flooding), Salinity stress, Elevated temperature and/or low temperature (chilling and freezing), Hypoxia and/or anoxia, Mineral nutrient excess and/or deficiency, Heavy metals and/or metalloids, Plant priming (chemical, biological, physiological, nanomaterial, biostimulant) approaches for improved stress protection, Viral, phytoplasma, bacterial and fungal plant-pathogen interactions. The journal welcomes basic and applied research articles, as well as review articles and short communications. All submitted manuscripts will be subject to a thorough peer-reviewing process.
