The suspected grains are soaked in water in flat, shallow bottomed basins with water level about two inches above the level of grain. Plant disease resistance is often conferred by genes with nucleotide binding site (NBS) and leucine-rich repeat (LRR) or serine/threonine protein kinase (S/TPK) domains.
