The clonal-crop economy is enormous — and exposed

Most high-value perennial and tissue-cultured crops are propagated clonally. The genetics of a single cultivar can underwrite billions of dollars of plantings over decades. Even row crops and annuals can ride on tissue-cultured stock that needs verification. Tap any crop to see why genomic screening matters there.
