Climate-resilient sunflower crops can help to reduce the EU dependency on imports of vegetable oils and proteins shifting towards sustainable alternatives, to mitigate the impact of agricultural production on water use and greenhouse gas emissions, to grow resources for pollinators, and to promote biodiversity. HelEx will generate the knowledge and use innovative tools to accelerate the breeding of sunflower varieties adapted to extreme drought and heat stresses, while improving their environmental impact and assessing their socio-economic value of the resulting innovations along the value chains. HelEx will thereby consider two related groups of traits increasingly impacted by climate change, i.e. the eco-systemic service to pollinators and seed quality. For this, HelEx brings together scientists, SMEs, and industries representing an international consortium of experts in sunflower ecology, physiology and genomics; plant biotechnology and breeding; pollinator biology and ecology; environmental impact assessment and feedstock processing; and socioeconomic assessment at different scales. This HelEx multi-disciplinary consortium will explore the genetic and molecular processes involved in tolerance to drought and heat in wild extremophile Helianthus species, and identify favorable wild alleles introgressed into cultivated sunflower, for seed quality and pollinator attractiveness resilience (WP1). These processes will be transfered using classical marker-assisted selection and innovative genome editing approaches (WP2), and the environmental and biodiversity impact of these new climate-smart sunflowers assessed (WP3). HelEx will investigate the socio-economic impact and benefits in relevant value chains for different feedstock (WP4). Our communication strategy (WP5) will engage a variety of societal stakeholders to ensure feedback and enhance project progress and outcomes, and make transparent the broader dimensions of plant biotechnology, biodiversity, and benefit sharing

The EU requires rapid and effective actions based on innovative detection concepts targeting quarantine, priority and other serious pests. Fair, healthy and environment-friendly food systems are threatened by increasing pest invasions due to climate change and a growing demand for high quality, pest-free food. The goal of PurPest is to develop, validate and demonstrate an innovative sensor platform that can rapidly detect five different pests during import and in the field to stop their establishment and reduce pesticide inputs by at least 50%. The sensor concept is based on detection of pest-specific volatile organic compounds (VOCs) emitted by host plants invaded by one or several pests. PurPest will determine the VOC signature of Phytophthora ramorum, the Fall armyworm, the Cotton bollworm, the Brown marmorated stinkbug and the Pinewood nematode under different abiotic stress conditions. The VOC database will be exploited to optimize existing and develop new sensor concepts to detect pest-specific VOCs, starting from proof of concept (TRL3) to demonstration in field trials (TRL6). Non-invasive, reliable and rapid pest sensing platforms will increase pest screening efficiency from currently 3% to 80% of plant imports. Preventing outbreaks of new pests and site-specific pesticide use by early detection are the cornerstones of sustainable and integrated pest management (IPM). PurPest will evaluate the socio-economic and ecological impact of 5 pests and how the new detection concept affects these impacts. Direct communication with stakeholders via the advisory board, workshops and webinars is part of PurPest’s multi-actor approach to affirm involvement of all interest groups along the value chain The PurPest project is a strong multidisciplinary consortium with expertise from 10 countries, 7 universities, 5 research institutes, 4 SMEs and 2 governmental agencies.

Soil-borne plant-parasitic nematodes are a biosecurity risk for global food production with an estimated annual loss of €110 billion worldwide. Root-knot nematodes (RKN) and potato cyst nematodes (PCN) rank 1 and 2 in the Top 10 of high-impact plant-parasitic nematodes with RKN alone accounting for ~5% of global crop losses. RKN and PCN are A2 quarantine pests or emerging species listed on the EPPO Alert List. The two PCN species are also included in EU Commission implementing regulation 2021/2285. Recent reports document the emergence of new RKN and PCN problems in tomato and potato cropping across Europe and beyond due to two independent drivers: global warming and genetic selection. For decades, non-specific, environmentally harmful agrochemicals have been applied to manage RKN and PCN. The increasing awareness about their negative impact prompted the phasing out of most nematicides. Consequently, there is an urgent need for novel, durable control strategies that enable adequate responses by stakeholders to prevent crop losses in the EU and beyond. NEM-EMERGE will provide a spectrum of sustainable, science-based solutions for both the conventional and organic farming sector based on the principles of IPM, including (1) optimized crop rotations schemes including cover crops, (2) tailored host plant resistances, and (3) optimal use of the native antagonistic potential of soils. Moreover, monitoring and risk assessment tools will be generated to support Plant Health Authorities in decision and policy making. To ensure the adoption and implementation of NEM-EMERGE tools in the sector, a bottom-up co-creation process and multi-actor approach will be used based on stakeholder demands from both the conventional and organic sector. This makes NEM-EMERGE a key driver for the transition to sustainable farming in line with the Farm to Fork Strategy thereby contributing to the challenging targets set by the Green Deal.

Crop wild relatives (CWR) are wild plant taxa closely related to a crop. They represent an important source of genetic diversity for the improvement of agronomic traits. In the context of the One Health Initiative, temperate fruit trees are essential for human nutrition and health, yet CWR resources have hitherto been underused. Moreover, fruit tree long lifespan and a current production dominated by a few cultivars make them particularly vulnerable to the effects of global changes. To address this challenge, the FRUITDIV project will monitor, characterise, use, and conserve the diversity of emblematic fruit tree CWR, with a particular emphasis on Malus, Pyrus and Prunus. To better characterise the genetic and phenotypic diversity of CWR fruit trees and identify favourable traits for future introgression into cultivars, FRUITDIV will use a combination of floristic, ethnogeography and population genomics on genebanks and historical European hotspots of diversity. We will then develop new multiomics-based breeding strategies that combine marker-assisted introgression for traits of interest (e.g. resilience, resistance to pests and diseases, fruit quality) with pangenomic prediction and a reduction of CWR-associated genetic load. In addition to breeding programs, FRUITDIV will also work with networks of farmers and associations to help characterise CWR progeny in various pedo-climatic conditions in Europe. An European-wide online platform that provides genotyping and phenotyping data for free will be implemented to promote the use of CWR genitors by breeders and farmers and help disseminate plant material of interest for various usages and cultivation systems. Overall, the FRUITDIV multi-actor approach involving geneticists, forestry officers, germplasm curators, farmers and citizens, will foster the in- and ex-situ conservation of CWR and promote sustainable agricultural practices across Europe.

Agrobiodiversity is a vital subset of biodiversity and is the result of the interaction between the environment, genetic resources and management systems used by culturally diverse people. It is a crucial prerequisite for ecologically and economically sustainable agricultural systems and is an important tool for ecological intensification. The aim of CROPDIVA is to reinforce agrobiodiversity on different levels and along distinct geographic and socio-economic areas. The activities of CROPDIVA are clustered around five connected research work packages and three pillars, each with a set of specific objectives: i) promotion of six key underutilised arable crops: oats, hull-less barley, triticale, buckwheat, faba bean and lupin; ii) creation of value chains for selected underutilised crops ; and iii) study of the socio-economic impact of project results. The concept of CROPDIVA is an innovative challenge driven approach based on the promotion of underutilised crops in sustainable cropping systems and new regional value chains. Project activities will focus on the following major challenges: improved resilience of cropping systems, alignment of the economic and social needs of farmers with ecological goals as well as marketing of new food/non-food products meeting consumer demands. The results gathered in CROPDIVA will not be descriptive, but will be used for innovative solutions along the entire food and non-food chain to enable biodiversity management on all levels, including diversifying the use of genetic resources, crop production systems, new food/non-food products, market opportunities while satisfying producers and investigated consumer requirements.
