Plant abiotic stresses are the major constraint on plant growth and development, causing enormous crop losses across the world. Plants have unique features to defend themselves against these challenging adverse stress conditions. They modulate their phenotypes upon changes in physiological, biochemical, molecular and genetic information, thus making them tolerant against abiotic stresses. It is of paramount importance to determine the stress-tolerant traits of a diverse range of genotypes of plant species and integrate those traits for crop improvement. Stress-tolerant traits can be identified by conducting genome-wide analysis of stress-tolerant genotypes through the highly advanced structural and functional genomics approach. Specifically, whole-genome sequencing, development of molecular markers, genome-wide association studies and comparative analysis of interaction networks between tolerant and susceptible crop varieties grown under stress conditions can greatly facilitate discovery of novel agronomic traits that protect plants against abiotic stresses.
植物非生物胁迫是植物生长和发育的主要限制因素，导致全球范围内作物大量减产。植物具有独特的特征来抵御这些具有挑战性的不利胁迫条件。它们根据生理、生化、分子和遗传信息的变化来调节表型，从而使它们能够耐受非生物胁迫。确定植物物种不同基因型的耐胁迫特性并整合这些特性以进行作物改良至关重要。通过高度先进的结构和功能基因组学方法，对耐胁迫基因型进行全基因组分析，可以鉴定出耐胁迫特性。具体来说，全基因组测序、分子标记的开发、全基因组关联研究以及在胁迫条件下生长的耐受和易感作物品种之间的相互作用网络的比较分析，可以极大地促进发现保护植物免受非生物胁迫的新型农艺性状。
