Synthetic biology is a multidisciplinary field that applies engineering principles to the creation of biological systems and the re-design of existing ones for useful purposes. One of the crucial engineering principles needed for the successful implementation of synthetic biology solutions is the modularization and standardization of biological parts. That is a “toolbox” of well characterized elements that can be combined inside cellular systems to obtain the desired effect. In this work, we explore two module candidates for synthetic biology. Firstly, we test the feasibility of hijacking the unfolded protein response through a mRNA module in a plant system as a way to avoid cytotoxicity from synthetic pathways. Secondly, we purified CURT1A from a plant system with the future perspective of gathering structural data. That knowledge could help to better understand the biological function of the CURT1 family as well as their further characterization as a tool for synthetic membrane protein scaffolding. Following this line, we also summarize recent advances on synthetic protein scaffolding anchored to biological membranes. Finally, we present an easy and fast alternative system for the selection of Arabidopsis thaliana stable transformants to facilitate research in plant synthetic biology and many other fields.
