Hybrid mimics and hybrid vigor in Arabidopsis

Wang, Li; Greaves, Ian K; Groszmann, Michael; Wu, Li Min; Dennis , Elizabeth S; Peacock, W James

Description

F1 hybrids can outperform their parents in yield and vegetative biomass, features of hybrid vigor that form the basis of the hybrid seed industry. The yield advantage of the F1 is lost in the F2 and subsequent generations. In Arabidopsis, from F2 plants that have a F1-like phenotype, we have by recurrent selection produced pure breeding F5/F6 lines, hybrid mimics, in which the characteristics of the F1 hybrid are stabilized. These hybrid mimic lines, like the F1 hybrid, have larger leaves than...[Show more]
