How Art and Science are Helping Chicory: An Inside Look at the New CHIC Project

Posted on February 21st, 2019 by Marcel Bruins

Among the various projects which are supported through the EU Horizon 2020 funding programme is the CHIC research and innovation project. It plans to establish a responsible innovation pathway for developing and using New Plant Breeding Techniques (NPBTs) for chicory as a multipurpose crop for the production of inulin and terpenes.

Root chicory (Cichorium intybus L.) is an under-utilized crop. It is currently used for the commercial production of inulin, which is added to many food products as a dietary fibre and sweetener. The CHIC project aims to develop chicory varieties that can be used to produce dietary fibre with enhanced prebiotic effects to promote gut health. At the same time, given its biosynthetic capacity, high yields and low agronomic requirements, chicory has significant potential as a versatile production host in molecular farming for the production of many additional health-related products with benefits for consumers. CHIC also aims to harness this potential for the extraction of other types of health-related compounds such as terpenes as potential lead molecules for drug development. To achieve this, new chicory varieties must be developed. However, chicory breeding is currently exceptionally time-consuming. Since it is an obligatory outcrossing species, no true varieties can be obtained, and germplasm is maintained by in vitro propagation. European Seed sat down with project coordinator Macarena Sanz, CHIC Dissemination and Communication Manager.

European Seed (ES): Macarena, can you tell me a bit more about the CHIC project?

Macarena Sanz (MS): CHIC aims at developing chicory varieties as a crop to increase the diversity and sustainability of agricultural production while serving consumer needs. These varieties will require less agrochemical and shall produce improved dietary fibres and medical compounds. CHIC also aims to facilitate a transparent discussion and create awareness about new plant breeding techniques (NPBT) such as CRISPR. We will compare their efficacy, potential risk, evaluate socio-economic consequences and develop business plans for commercialization.

ES: Why was chicory chosen for this project over other crops?

MS: The idea of the European Commission was to address minor utilised non-food crops that produce interesting compounds and have potential for molecular farming. Chicory is just like that – it is a crop that grows in the north of Europe, predominantly in France, The Netherlands and Belgium. It is already used for the commercial production of inulin and the processing pipeline is in place. Chicory can become a multipurpose crop, since it also produces interesting terpenes.

ES: The project plans on using new plant breeding techniques. However, the ECJ recently ruled that such techniques should be regulated as GMO’s. Isn’t that a drawback for the project?

MS: This shows the importance of projects like this, and perhaps they are needed now more than ever. By using NPBT, CHIC will develop chicory plants with consumer benefits. We will assess the products as well as the methods used, their safety and their possible socio- and economic impact. We will do this by enhancing interactions and open communication with stakeholders, including the public. In doing so, we aim to boost awareness and take into consideration all the needs and concerns we will detect during the whole length and development of the project.

ES: Will the CHIC project be using mainly techniques based on CRISPR-Cas, or also using other techniques?

MS: Yes, CRISPR is the main technique that will be used. We will use different variants and see which ones best fit chicory.

ES: How are you planning to raise awareness and improve the interaction with the public?

MS: In our project we will reach out to the public by engaging them with several activities. We will develop and implement a solid publication strategy which will allow us to disseminate publishable data to researchers by using traditional channels (such as symposia, journals, presentations at conferences etc.) and to engage with key stakeholders. Communication with stakeholders and the general public will be crucial, since our objective is to increase public awareness and appreciation of NPBTs to generate valuable natural products – this is particularly relevant in case of potential consumers and new products. Training activities aimed at school children and households will be organised allowing researchers and interested stakeholders to gain knowledge and skills in the NPBTs relevant to the project. To this purpose, we will organise four CHIC days in different European schools for teenagers (age 14 – 16) to educate them about “hot topics” such as new plant breeding techniques. Moreover, the educational material will be designed for teenagers and disseminated through smartphones/tablet application. This will include demos and games to explain in an education, visual and interactive way the relevance of these topics, such as the positive impact of NPBTs, GMOs on human health and increasing food demands. In addition to this, we will guarantee an active presence on social media channels and organise initiatives to involve artists, since art is an effective ´language´ when it comes to transmit knowledge, values and stronger connection with the audience.

ES: You plan on using artists to better convey the relevant messages. What will be the additional benefits of using artists?

MS: Because art and science are more closely related than we think. Both science and art are human attempts to understand and describe the world around us. Art can not only provide the audience with information, but also elicit visceral, emotional responses and engage the imagination in ways that prompt action and a positive attitude towards such complex topics that could be hard to explain with words and scientific notions. For these reasons, involving artists in the project could attract a broader audience, such as people that would otherwise not be interested in science developments, since it´s a more evocative and effective way of communicating.

ES: How do you plan to assess the impact on the sustainability of the CHIC project?

MS: Within the CHIC project a socio-economic and an environmental assessment will be done. Regarding socio-economic impacts, we will assess how different NPBTs will influence economic and social indicators such as GDP (Gross Domestic Product), production volume, growth, competitiveness, and employment as well as the distribution of wealth and income between different sectors and regions within the EU.

The assessment of environmental issues will be done with the methodology of Life Cycle Assessment (LCA) which is an established method of environmental assessment providing information about environmental aspects over the whole life cycle. The LCA will be performed on the NPBTs and based on the whole value chain from breeding, cultivation, harvesting, processing to the final products (inulin and terpenes). The most relevant environmental aspects and parameters (e.g. GHG emissions, primary energy consumption, land use aspects, water issues) with their influencing factors will be identified and compared to a conventional reference system.

ES: In certain fields there is a feeling of growing opposition against innovation, including in agriculture and the seed sector. How can we overcome this opposition?

MS: I am not sure there is growing opposition against innovation. There are many innovation projects going on in the food and agriculture fields, and we need at all costs to better interact with the target we want to reach, if we want to be successful.

ES: How will the private sector be involved in the CHIC project?

MS: The private sector are partners in the project. Stakeholders from the private sector will be involved throughout the project (e.g. farmers, processors, food companies etc).

ES: Do you expect that the outcome can be translated to other crops?

MS: Yes, we do. Both the technologies and the ways to interact with society.

Plant breeding techniques in a new era

Scientists of Wageningen University & Research have published a concise booklet that gives some new insights into several aspects of plant breeding techniques such as CRISPR-Cas: ‘Plant breeding techniques in a new era’.

In recent years a range of New Plant Breeding Techniques (NPBTs) has been developed that can assist breeders in a more efficient and precise adjustment of the genetic constitution of crops. These techniques include genome editing techniques, which have made tremendous progress since the introduction of CRISPR-Cas in 2012. These new techniques will support plant breeders in improving important crop traits that always have been difficult to improve via cross breeding.

Worldwide, agriculture is facing serious sustainability issues which need to be addressed through an integrated approach that covers the entire production chain. Plant breeders and plant breeding companies are at the base of that chain. Plant breeders will need to develop new varieties in a shorter period of time to keep up with changes in climatic conditions, soil quality and pathogen & pest pressures, increasing food demand, and the evolving preferences of consumers.

Plant breeders are eager to apply new plant breeding techniques. Society wants to know more about the techniques. That is why scientists of Wageningen University & Research have made a booklet giving a brief overview of recent developments in plant breeding techniques. In this booklet the scientists describe examples of techniques and of desirable crop traits that may be improved using genome editing. They also discuss societal, legal and economic aspects of new plant breeding techniques.

What are New Plant Breeding Techniques (NPBTs)

NPBTs are innovative tools that enable plant breeders to develop novel plant varieties that may provide solutions for environmental and food quality as well as food supply challenges.

Conventional plant breeding generally relies on techniques of which the outcome is difficult to predict, requiring between seven and twenty-five years, depending on the species, to generate the desired characteristics and to introduce these into stable and uniform new plant varieties.

NPBTs allow the plant breeding industry to produce plant varieties in a similar – but more precise – manner compared to conventional breeding techniques, in a significantly shorter timeframe.

The precise increase in speed depends on the species of plant, the desired property and in some cases, the technique used. For example, scab-resistant apples have been produced by use of cisgenesis in approximately 12 years, compared to an exceptionally long period of 50 years with conventional breeding techniques. A rough estimate is that NBTs decrease the breeding timeframe by 50%.

It can be anticipated that, as science on NPBTs progress and breeders start practically using these techniques, further refinements and efficiencies will be found, which will lead to an additional reduction of the plant breeding lead time.

Since research into novel techniques of plant breeding is ongoing and evolving continuously, there is no finite set of NBTs and future techniques may be put under the same ‘umbrella term’. The NBT Platform has chosen to focus on the seven principal NBTs as proposed by the EU Competent Authorities to the New Techniques Working Group[1], as well as by the Joint Research Commission in their respective reports on NBTs[2].

These seven techniques are:

  1. Site-Directed Nucleases (SDN) (as representative of a growing group of related techniques including amongst others Zinc Finger Nuclease-1/2/3, TALENs, Meganucleases and CRISPR systems)
  2. Oligonucleotide Directed Mutagenesis (ODM)
  3. Cisgenesis
  4. RNA-dependent DNA methylation (RdDM)
  5. Grafting (non-GM scion on GM rootstock)
  6. Reverse breeding
  7. Agro-infiltration (Agro-infiltration ‘sensu stricto’, Agro-inoculation)

By developing and implementing a set of NPBTs, CHIC project will adapt the biosynthesis and architecture of root chicory. This will strengthen chicory as a production system for high-quality dietary fibres and establish it as a source of bioactive terpenes.

NPBTs are of utmost importance for plant breeders in Europe, as they provide them with a ‘toolbox’ of innovative plant breeding methods alongside the traditional methods, which allow them to remain globally competitive. Most of the world’s research on NPBTs was done in Europe, totalling to almost 46% of research published up to 2011[3].
