“…This level of conservation corresponds with the evidence that the cotton genomes are quite static structurally, particularly in the transition from diploidy to allopolyploidy , and was predicted by early cytological observations (reviewed by Endrizzi et al 1985). This contrasts with other plant genomes that have undergone more extensive restructuring (Quiros et al 1994;Song et al 1995;Lagercrantz and Lydiate 1996;Feldman et al 1997;Liu et al 1998a, b). This gross structural conservation will increase the transferability of information across genomes.…”
