Shih et al. review how the many and diverse tools of plant synthetic biology can be applied towards bioenergy crops, focusing on traits related to lignocellulose, oil, and soluble sugars. Tools include those that edit genes, those that alter protein activities, and those that enable gene stacking in…

Nemhauser and Torii define synthetic biology as “an engineering approach to design, build and analyize dynamic molecular devices and/or pathways from biological components to produce cells and organisms with customized functionality.” In their review, they describe several plant synthetic biology…

Many plant traits are multigenic, so engineering them requires modulating the expression of several genes simultaneously. Synthetic promoters and transcription factors offer such a possibility. For example, a cis-element can be introduced into the promoter of each gene of interest, and a synthetic transcription…

Raitskin and Patron review efforts to express multiple single guide RNA (sgRNAs) and Cas9 in plants for the coordinated expression of many genes. They argue for the need to create single plasmids carrying the sgRNAs and Cas9, using a Type IIS restriction endonuclease-mediated assembly method. Curr. Opin.…

Puchta reviews the different ways that CRISPR/Cas9 can be used in synthetic biolgy, beyond the common gene-editing function. For example, the Cas9 protein can be fused to other proteins that activate or repress transcription, and targeted to different promoters using guide RNAs. He further explores the…

Control of gene expression involves both activation and repression of transcription. Schaumberg et al. used transient expression in Arabidopsis and sorghum protoplasts and dual-luciferase outputs to rapidly quantitate synthetic repressors and repressible promoters, and verified their results in transgenic…

Patron et al. describe the need to standardize DNA parts and terminology, so that researchers and inventors can use off-the-shelf parts (they draw an analogy to the standardization of components in mechanical and electronic engineering). New Phytol. 10.1111/nph.13532
