Doubling down on genomes: polyploidy and crop plants
S Renny‐Byfield, JF Wendel - American journal of botany, 2014 - Wiley Online Library
Polyploidy, or whole genome multiplication, is ubiquitous among angiosperms. Many crop
species are relatively recent allopolyploids, resulting from interspecific hybridization and …
