| Abstract | Abstract Arbuscular mycorrhizal fungi (AMF) constitute an important component of soil microbial communities and form symbiotic associations with a wide range of terrestrial plants. The present study investigated the diversity, species composition and spore abundance of AMF associated with the rhizosphere of Andrographis paniculata Nees in the Botanical Garden of Shri Shivaji Science College, Amravati, Maharashtra, India. Rhizosphere soil samples were collected from three sampling units within the Botanical Garden and examined for AMF spore occurrence and diversity. A total of 31 AMF species belonging to four genera, namely Acaulospora, Gigaspora, Glomus and Sclerocystis were recorded. The total AMF spore population was 901. Glomus was the predominant genus, comprising 21 species and 864 spores, representing 95.89% of the total spore population. Acaulospora comprised eight species and contributed 3.66%, whereas Gigaspora and Sclerocystis were represented by one species each and contributed 0.22% each. Among individual taxa, Glomus reticulatum exhibited the highest relative abundance (12.65%), followed by G. leptothicum (9.88%) and G. fasciculatum (7.33%). The Shannon-Wiener diversity index ranged from 2.943 to 2.976, while Simpson dominance values ranged from 0.061 to 0.064. The findings demonstrate that the rhizosphere of A. paniculata in the Botanical Garden harbours a diverse AMF assemblage characterized by considerable species richness and pronounced dominance of Glomus. The study provides baseline information on AMF diversity associated with a medicinal plant in the Amravati region. |
