During crop domestication and breeding, wild plant species have been shaped into modern high-yield crops and adapted to the main agro-ecological regions. However, climate change will impact crop productivity in these regions, and agriculture needs to adapt to support future food production. On a global scale, crop wild relatives grow in more diverse environments than crop species, and so may host genes that could support the adaptation of crops to new and variable environments. Through identification of individuals with increased climate resilience we may gain a greater understanding of the genomic basis for this resilience and transfer this to crops. Pangenome analysis can help to identify the genes underlying stress responses in individuals harbouring untapped genomic diversity in crop wild relatives. The information gained from the analysis of these pangenomes can then be applied towards breeding climate resilience into existing crops or to re-domesticating crops, combining environmental adaptation traits with crop productivity.
在作物驯化和育种过程中，野生植物物种已被培育成现代高产作物，并适应了主要的农业生态区域。然而，气候变化将影响这些地区的作物生产力，农业需要作出调整以保障未来的粮食生产。在全球范围内，作物野生近缘种生长的环境比作物物种更为多样，因此可能携带有助于作物适应新的多变环境的基因。通过识别气候适应能力增强的个体，我们或许能更深入地了解这种适应能力的基因组基础，并将其转移到作物中。泛基因组分析有助于识别作物野生近缘种中具有未开发基因组多样性的个体的应激反应相关基因。从这些泛基因组分析中获得的信息随后可应用于将气候适应能力培育到现有作物中，或将作物重新驯化，将环境适应性状与作物生产力相结合。
