Reference transcriptomes and comparative analyses of six species in the threatened rosewood genus Dalbergia.

ABSTRACT: Dalbergia is a pantropical genus with more than 250 species, many of which are highly threatened due to overexploitation for their rosewood timber, along with general deforestation. Many Dalbergia species have received international attention for conservation, but the lack of genomic resources for Dalbergia hinders evolutionary studies and conservation applications, which are important for adaptive management. This study produced the first reference transcriptomes for 6 Dalbergia species with different geographical origins and predicted ~ 32 to 49 K unique genes. We showed the utility of these transcriptomes by phylogenomic analyses with other Fabaceae species, estimating the divergence time of extant Dalbergia species to ~ 14.78 MYA. We detected over-representation in 13 Pfam terms includ
