Microbes and Metabolites in the Rafflesia–Tetrastigma Interaction
The interaction between the giant parasitic flower Rafflesia and its host vine Tetrastigma is one of the most fascinating relationships in plant ecology. Rafflesia is famous for producing the largest individual flower in the world, yet it cannot survive independently. It lives entirely inside the tissues of Tetrastigma vines, drawing nutrients and water from its host. Because it lacks leaves, stems, and roots, the parasite depends completely on its host plant for growth and reproduction. Scientists are increasingly studying the role of microbes in this unique plant–parasite interaction. Microbial communities living within plant tissues, known as endophytes, can influence plant health and interactions with other organisms. These microbes may affect how suitable a Tetrastigma vine is for Rafflesia infection, possibly helping the parasite establish itself inside the host. Another important factor in this relationship is the presence of plant metabolites. Metabolites are chemical compounds...
