摘要

Rhizospheric microbial symbiotic networks play a crucial role in maintaining plant fitness and development. Any disruption in these microbial community networks can adversely affect both plants and the soil ecosystem. Plant invasion is a major threat to global biodiversity, yet its impact on soil microbial communities’ disruption remains underexplored. Invasive species are highly aggressive and capable of suppressing native vegetation through competition or by secreting allelochemicals, which may interfere with soil functioning and alter soil physicochemical properties. In this study, we investigated the impact of Lantana camara L. invasion on the native medicinal plant Ocimum sanctum L., focusing on rhizospheric soil properties and microbial communities. We examined how Lantana camara presence affects Ocimum growth, soil physicochemical characteristics, and substrate utilization profiles using Average Well Colour Development (AWCD), along with metagenomic, nonculturable, and culturable analyses of rhizospheric bacterial communities associated with OS-0 (Ocimum without Lantana) and OS-L (Ocimum interacting with Lantana). Our findings reveal that Lantana presence changes the rhizospheric bacterial community and coincided with reduced native plant growth. Ocimum grown together with Lantana exhibited reduced phenotypic traits compared to Ocimum grown alone. Changes were observed in soil physicochemical properties and AWCD values. Both nonculturable and culturable analyses showed significant alterations in the rhizospheric bacterial communities between OS-0 and OS-L. These results suggest that the detrimental effects of Lantana presence on native plants are linked to disruptions in their microbial communities. Although presence of Lantana appears to enhance some of the soil nutrient availability, it simultaneously suppresses the growth and development of Ocimum by interfering with beneficial rhizospheric bacteria.
