Rafflesia floral buds emerge to produce the world’s largest single flower. Like other plants, holoparasites harbor a diverse microbiome, the role(s) of which has remained largely unstudied. We characterized the bacterial microbiome of seeds of Rafflesia speciosa and cuttings of its host. We found evidence that R. speciosa seed has similar bacterial profiles to its infected host, which suggests that seeds sequester certain host bacteria, as well as acquire unique bacterial taxa from biotic associates of the fruit. We did not find evidence of mycorrhizal taxa in the microbiome. This is the first study of the microbial endophytes associated with any Rafflesia species and its host, a tripartite holobiont, and provides insights on its cryptic microbial partners. We discuss how this may aid horticultural propagation of Rafflesia.", "collection-title": "Int J Syst Evol Microbiol", "container-title": "2024-06-17", "journalAbbreviation": "BMSAB", "language": "EN", "page": "6", "title": "Description of Galbitalea soli gen. nov., sp. nov., and Frondihabitans sucicola sp. nov.", "volume": "64", "author": [ { "family": "Kim", "given": "S-J" }, { "family": "Lim", "given": "J-M" }, { "family": "Ahn", "given": "J-H" }, { "family": "Weon", "given": "H-Y" }, { "family": "Hamada", "given": "M" }, { "family": "Suzuki", "given": "K-I", "suffix": "et.al" } ] }, { "id": "http://zotero.org/users/local/TaPjDov7/items/4G7WSK83", "type": "document", "abstract": "Cells rod-shaped, straight or slightly curved, occurring singly and in pairs, some in chains, and occasionally as long filaments.
