As these functional assays are expanded to the rest of the genome, they will likely play a critical role in expanding studies of rare variation beyond the exome and to the rest of the genome where identifying, aggregating and grouping functional variants remain much harder.
That call to expand studies of oft-neglected underground biodiversity is included in a new collection of papers timed to highlight World Soil Day, which is being celebrated today.
