Jamesianthus alabamensis (Blake and Sherff), is an Alabama endemic Asteraceae species first described in 1940 in Franklin County, Alabama. J. alabamensis has a limited distribution across Alabama, mainly found in the northern parts of the state with the majority of herbarium specimen coming from northwestern Alabama.Nested within the Tageteae (marigold tribe), J. alabamensis is closely related to Arnicastrum (Greenman), a genus containing two species found in Central Mexico, and Clappia suaedifolia (Gray), a monotypic genus found in the southern tip of Texas and adjacent areas of Mexico. All three genera have been placed within different tribes throughout history, with Arnicastrum and Jamesianthus often placed in the same tribes but Clappia being placed in separate tribes until more recent ITS sequencing data grouped all three in the Tageteae. Interestingly, both Jamesianthus and Clappia have unusual chromosome numbers (n = 16) for Tageteae species while Arnicastrum’s chromosome numbers have not been determined yet.  Here we present chromosome-scale haplotype resolved genome assemblies of J. alabamensis. These assemblies will help us to gain a better understanding of this species position within the Tageteae. Using comparative genomics, we aim to identify genome-scale changes or events shared by these three genera that could explain their similar life histories. This study has a particular focus on Jamesianthus alabamensis, where we plan on leveraging population-level data to understand its restricted distribution across Alabama as a part of a focused conservation effort.
