Green plants play a fundamental role in ecosystems, human health, and agriculture. As de novo genomes are being generated for all known eukaryotic species as advocated by the Earth BioGenome Project, increasing genomic information on green land is essential. However, setting standards generation storage of complex set that characterize lineage life major challenge plant scientists. Such will need to accommodate immense variation genome size, transposable element content, structural complexity while enabling research into molecular evolutionary processes have resulted this enormous variation. Here we provide an overview assessment current state knowledge genomes. To date fewer than 300 complete chromosome-scale assemblies representing 900 been across estimated 450,000 500,000 clade. These range size from 12 Mb 27.6 Gb biased toward agricultural crops with large branches tree untouched genomic-scale sequencing. Locating suitable tissue samples most plants, especially those taxa extreme environments, remains one biggest hurdles our inventory. Furthermore, annotation at present undergoing intensive improvement. It hope fresh help development quality cohesive meaningful synthesis scale up future.
