K. auteur aut IRD text journalArticle eng text/pdf born digital access Lipid research represents a frontier for microbiology, as showcased by hopanoid lipids. Hopanoids, which resemble sterols and are found in the membranes of diverse bacteria, have left an extensive molecular fossil record. They were first discovered by petroleum geologists. Today, hopanoid-producing bacteria remain abundant in various ecosystems, such as the rhizosphere. Recently, great progress has been made in our understanding of hopanoid biosynthesis, facilitated in part by technical advances in lipid identification and quantification. A variety of genetically tractable, hopanoid-producing bacteria have been cultured, and tools to manipulate hopanoid biosynthesis and detect hopanoids are improving. However, we still have much to learn regarding how hopanoid production is regulated, how hopanoids act biophysically and biochemically, and how their production affects bacterial interactions with other organisms, such as plants. The study of hopanoids thus offers rich opportunities for discovery. specialized 084 020 16 5 304-315 2018 1740-1526 https://www.documentation.ird.fr/hor/fdi:010072769 10.1038/nrmicro.2017.173 1740-1526 [F B010072769] https://www.documentation.ird.fr/hor/fdi:010072769 https://www.documentation.ird.fr/intranet/publi/2018/05/010072769.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2018-06-01 2023-07-11 fdi:010072769 fre
