In 2020 we published genome assemblies for many species of ash (Fraxinus) from around the world in Nature Ecology and Evolution. These assemblies and read data are available as shown in Table 1 below.
We have since annotated these assemblies, and improved the assemblies of 13 species de novo using using long mate pair libraries. These unpublished assemblies and annotations can be found here: 
We have generated transcriptomic data for Fraxinus mandshurica, Fraxinus ornus, Fraxinus quadrangulata and Fraxinus gooddingii. The reads can be found in Bioproject PRJNA934306 on NCBI SRA.
In 2021 we collaborated in the publication of a major new assembly and annotation of Green ash (Fraxinus pennsylvanica) in Molecular Ecology Resources. This chromosome-level assembly can be downloaded here: 
. Within this paper we also presented new reference-guided scaffolding of the ash species assemblies published previously. See:

The first assemblies for the world-wide species were funded by Living with Environmental Change: Tree Health and Plant Biosecurity Initiative – Phase 2 Grant, BB/L012162/1 to Richard Buggs, funded jointly by a grant from BBSRC, Defra, ESRC, the Forestry Commission, NERC and the Scottish Government. This project has also received funding from the European Union’s Horizon 2020 research and innovation programme under the Marie Sklodowska-Curie grant agreement No 660003.
