Introducing the UK Crop Microbiome Cryobank data resource, AgMicrobiomeBase, with case studies and methods on metabarcoding analyses.

Here, we describe AgMicrobiomeBase as an output of the UK Crop Microbiome Cryobank (UKCMCB) project, including details of the underlying meta-barcode sequence-based methods and three microbiome analysis case studies. The UKCMCB links genomic datasets and associated soil metadata with a cryobank collection of samples, for six economically significant crops: fava bean (Vicia faba), oil seed rape (Brassica napus), spring barley (Hordeum vulgare), spring oats (Avena sativa), spring wheat (Triticum aestivum) and sugar beet (Beta vulgaris). The crops were grown in nine agricultural soils from the UK, representing three major soil texture classes. The UKCMCB is a scalable sequence-based data catalogue linked to a cryo-preserved sample collection.
