Carnivorous plants grow in low soil and low nutrient concentration. They depend on the insect for nitrogen source and also perform photosynthesis to obtain energy. However, how do they trap the nutrients from soil is debatable. To uncover this fact, we intend to study the fungal association in the rhizosphere of Utricularia purpurascens and Utricularia striatula obtained from Amboli. The fungal association was considered because the root systems of carnivorous plants are weakly developed. Based on the understanding of fungal structures like the presence of hyphae and mycelia, fungi may aid in nutrient acquisition for the plant. Like most plants face a trade-off with growth, reproduction, and development, they evolve to produce some volatile components or signaling molecules. To understand this mechanism, rhizosphere soil of the carnivorous plants was diluted. The soil around the roots of the plant was used to culture the fungus and to perform the morphological identification. Ten different fungi were observed in the culture plate. These fungi were further checked for pectinase, chitinase and protease activity. These activities are thought to up-regulated in response to insect or worm prey observed around the rhizosphere. Indole acetic acid production, phosphate Solubalization activities were also considered to comprehend nutrient absorption by the plant. Since little is known about the associations with carnivorous plants and fungi, this study may give an insight into rhizosphere interaction with Carnivorous plants. It may also aid to understand the trapping strategy utilized by prey and predator in search of nutrients.
