Recent degeneration of an old duplicated flowering time gene in Brassica nigra.

Heredity - 1 Jun 2007

Sjödin P, Hedman H, Shavorskaya O, Finet C, Lascoux M, Lagercrantz U

Abstract excerpt

Gene and genome duplications play a major role in the evolution of plant species. The Brassica nigra genome is highly replicated as a result of ancient polyploidization events. Two copies of the flowering time gene CONSTANS (COa and COb) have been identified in B. nigra, and previous studies show...
