气候变化影响全球农业生产力。粮食商品价格上涨是可食用产量急剧下降的初步迹象，由于全球变暖，这种下降预计将进一步加剧。这种情况迫使植物科学家开发适应气候变化的作物，这种作物能够承受干旱、高温、寒冷、盐碱、洪水、淹没和虫害等广泛的压力，从而有助于提高生产力。基因组学似乎是一个很有前途的工具，破译适应性状的作物物种或野生近缘种的压力响应，以确定潜在的基因，等位基因或数量性状位点。事实证明，分子育种方法有助于增强作物植物的胁迫适应能力，高通量测序和表型分析平台的最新进展已将分子育种转变为基因组辅助育种（GAB）。有鉴于此，本审查阐述了GAB在提高作物气候变化适应能力方面的进展和前景，这可能在确保全球粮食安全的努力中发挥越来越大的作用。
Climate change affects agricultural productivity worldwide. Increased prices of food commodities are the initial indication of drastic edible yield loss, which is expected to increase further due to global warming. This situation has compelled plant scientists to develop climate change-resilient crops, which can withstand broad-spectrum stresses such as drought, heat, cold, salinity, flood, submergence and pests, thus helping to deliver increased productivity. Genomics appears to be a promising tool for deciphering the stress responsiveness of crop species with adaptation traits or in wild relatives toward identifying underlying genes, alleles or quantitative trait loci. Molecular breeding approaches have proven helpful in enhancing the stress adaptation of crop plants, and recent advances in high-throughput sequencing and phenotyping platforms have transformed molecular breeding to genomics-assisted breeding (GAB). In view of this, the present review elaborates the progress and prospects of GAB for improving climate change resilience in crops, which is likely to play an ever increasing role in the effort to ensure global food security.
