Raw sequencing reads from herbarium specimens collected for the study "Shifts in evolutionary lability underlie independent gains and losses of root-nodule symbiosis in a single clade of plants." The method of data collection has been reported extensively in Folk et al. 2021: https://doi.org/10.1002/aps3.11410. Methods related to sequence assembly can be found in Kates et al. 2021 https://doi.org/10.3389/fpls.2021.669064.
