Genomic resources for two threatened Vriesea species
This project aims to generate high-quality, chromosome-scale genome assemblies for two threatened bromeliad species, Vriesea longistaminea and Vriesea minarum, both endemic to the campos rupestres of the Iron Quadrangle, Brazil. These species are characterized by restricted distributions and are under increasing threat due to habitat loss associated with mining activities. Genomic data were generated using PacBio HiFi long-read sequencing combined with Hi-C chromatin conformation capture to produce haplotype-resolved genome assemblies. Additionally, RNA-seq data from multiple tissues were generated to support structural and functional genome annotation. These genomic resources provide a foundation for studies on genome evolution, adaptation to extreme edaphic conditions, and conservation genomics of microendemic plant species. The datasets are intended to support future research on biodiversity conservation and to inform strategies for the preservation of threatened ecosystems.
