Abiotic stresses constitute a significant threat to global crop production, and this problem is likely to be exacerbated in the future due to climate change. Soil salinity affects more than 60 million hectares of irrigated land, and continuously increasing day by day.Worldwide crop production must be doubled by 2050 to feed the increasing population, estimated to be 9 billion. Although significant progress has been made in crop improvement, most efforts have targeted above-ground traits in plants. Roots are essential for plant adaptation and productivity but are significantly less studied due to technical difficulties. Barley is the fourth most important cereal crop worldwide. To date, most of the research focused on improving the malt quality of barley. However, it is also necessary to assemble new cultivars with increased adaptation to abiotic stresses to ascertain Climate-Smart Agriculture. PlastiRootS focuses on deciphering the natural variation of root plasticity under salinity stress in barley germplasm via advanced non-destructive root phenotyping techniques networked with fatty acid profiling. Additionally, PlastiRootS aims to identify key genes responsible forthe modulation of root plasticity under salinity stress by a genome-wide association study. Further, the multiplexed CRISPR gene editing system for functional validation of candidate genes in barley will be utilised to reveal the adaptive response of root traits to salt stress. The PlastiRootS offers an unprecedented opportunity for addressing novel aspects in root biology and will provide a foundation for future breeding efforts toward superior root traits against salinity stress tolerance in barley. This project will contribute to the UNSDGs and inclusive green economy strategies to produce more food with fewer resources, achieve food security, promote sustainable agriculture, and economic opportunity through agriculture and combat climate change and its impact.

非生物压力对全球作物产量构成了重大威胁，由于气候变化，这一问题可能会加剧。土壤盐度影响了超过6000万公顷的灌溉土地，并且每天不断增加。在2050年之前，遍布农作物的产量必须翻了一番，以喂养增加的人口，估计为90亿。尽管在作物改善方面取得了重大进展，但大多数努力都针对植物的地上特征。根对于植物适应和生产力至关重要，但由于技术困难而研究的研究大大降低。大麦是全球第四种最重要的谷物作物。迄今为止，大多数研究都集中在提高大麦的麦芽质量。但是，还必须组装新品种，以增加对非生物压力的适应性，以确定气候智能农业。 Plastiroot的重点是通过高级非破坏性根表型技术与脂肪酸分析网络的晚期非破坏性根表型技术在盐度胁迫下的根部可塑性的自然变化。此外，Plastiroots旨在通过一项全基因组关联研究来确定负责在盐度应激下调节根部可塑性的关键基因。此外，将利用用于大麦候选基因功能验证的多重CRISPR基因编辑系统，以揭示根性状对盐胁迫的适应性反应。 Plastiroots为解决根生物学的新方面提供了前所未有的机会，并将为未来的繁殖努力奠定基础，以抗击大麦的盐度胁迫耐受性。该项目将有助于UNSDGS和包容性的绿色经济战略，以减少资源，实现粮食安全，促进可持续农业以及通过农业和打击气候变化及其影响的经济机会生产更多粮食。
