Cell-free systems in the new age of synthetic biology

Fernando Villarreal,Cheemeng Tan

Frontiers of Chemical Science and Engineering 2017, Volume 11, Issue 1,   Pages 58-65 doi: 10.1007/s11705-017-1610-x

Abstract: The advent of synthetic biology has ushered in new applications of cell-free transcription-translation systems. These cell-free systems are reconstituted using cellular proteins, and are amenable to modular control of their composition. Here, we discuss the historical advancement of cell-free systems, as well as their new applications in the rapid design of synthetic genetic circuits and components, directed evolution of biomolecules, diagnosis of infectious diseases, and synthesis of vaccines. Finally, we present our vision on the future direction of cell-free synthetic biology.

Age-related trends in genetic parameters for wood properties in

Chao SUN, Meng LAI, Shougong ZHANG, Xiaomei SUN

Frontiers of Agricultural Science and Engineering 2017, Volume 4, Issue 4,   Pages 482-492 doi: 10.15302/J-FASE-2017184

Abstract: We observed that age-related trends in overall means varied for different traits: MFA decreased withthe age, while the others generally increased with the age.After the age of 6, genetic correlations were generally higher than phenotypic correlations.Estimates of early selection efficiency suggested that the optimal selection age for wood density wasat age 5–6 years, while it was 9–10 years for the other traits.
