Synthetic Biology for engineering plants

Synthetic Biology is an emerging field that employs engineering principles for constructing genetic systems. The approach is based on the use of well characterised and reusable components, and numerical models for the design of biological circuits.

We have constructed a series of tools for controlling gene misexpression and marking specific cells in growing plants. We are building a new generation of genetic circuits that incorporate intercellular communication, and could be used to generate self-organised behaviour at the cellular scale. These could be used to reprogram plant development and morphogenesis.

PhD studentships in Cambridge
The UK government recently announced a new programme for PhD studentships, and some of these are filtering through to Cambridge. For information about synthetic biology research projects in the Haseloff Lab at the University of Cambridge, click here. The best place to find general information about postgraduate study at the University of Cambridge is the Graduate Admissions site. This includes customised links to potential funding sources for UK and international students.

Project ideas for 2017-2018
The lab hosts undergraduates for research projects in the Department of Plant Sciences. Students may be taking the third year of their Natural Sciences Tripos (Part II) or fourth year of a Master's Degree in Engineering. Students will have a day-to-day supervisor, and projects are generally customised for the individual, but a list of broad areas of interest can be found here. Please contact Prof. Jim Haseloff for more detailed information.

Biomaker projects on

Stacks Image 108995
The annual Biomaker Challenge and Open Technology Week will showcase for open source technologies for research and education developed across Cambridge and beyond. The advance of open source software, open hardware systems such as Arduino and Raspberry Pi, alongside 3D printing technologies and open biological tools, is promoting a maker ethos in science.

We have established a channel for Biomaker and OpenPlant projects on the website. This provides access to a large community with all major hardware manufacturers, around 10,000 projects and an audience of almost 300,000 viewers. The new Biomaker channel can be found at:
We welcome any related project submissions.

Synthetic Botany
Plants’ modular and plastic body plans, capacity for photosynthesis, extensive secondary metabolism, and agronomic systems for large-scale production make them ideal targets for genetic reprogramming. We highlight new approaches to the DNA-based manipulation of plants and the use of advanced quantitative imaging techniques in simple plant models such as Marchantia polymorpha. These offer the prospects of improved understanding of plant dynamics and new approaches to rational engineering of plant traits. Christian R.

MarpoDB: An open registry for Marchantia polymorpha genetic parts
MarpoDB is an open source database for Marchantia genes and DNA parts, which has been designed as a tool for a synthetic biology workflow. Among its features are precompiled cross-database querying to InterPro, Pfam signatures and non redundant Viridiplantae BLAST annotations; BLAST querying to Marchantia genes; sequence export in GenBank format; recoding of sequences to the common syntax for type IIS assembly and exchange of DNA parts; and a user interface for gene models and sequence exploration. MarpoDB is a platform for plant synthetic biology experiments in this model system.
