ABSTRACT

Plant abiotic stresses negative affects growth and development, causing a massive reduction in global agricultural production. Rapeseed (Brassica napus L.) is a major oilseed crop because of its economic value and oilseed production. However, its productivity has been reduced by many environmental adversities. Therefore, it is a prime need to grow rapeseed cultivars, which can withstand numerous abiotic stresses. To understand the various molecular and cellular mechanisms underlying the abiotic stress tolerance and improvement in rapeseed, omics approaches have been extensively employed in recent years. This review summarized the recent advancement in genomics, transcriptomics, proteomics, metabolomics, and their imploration in abiotic stress regulation in rapeseed. Some persisting bottlenecks have been highlighted, demanding proper attention to fully explore the omics tools. Further, the potential prospects of the CRISPR/Cas9 system for genome editing to assist molecular breeding in developing abiotic stress-tolerant rapeseed genotypes have also been explained. In short, the combination of integrated omics, genome editing, and speed breeding can alter rapeseed production worldwide.

摘要

植物非生物胁迫对生长和发育产生负面影响，导致全球农业产量大幅下降。油菜 ( Brassica napus)L.) 是一种主要的油籽作物，因为它具有经济价值和油籽产量。然而，许多环境逆境降低了它的生产力。因此，种植能够承受多种非生物胁迫的油菜品种是首要需求。为了了解油菜籽非生物胁迫耐受性和改良的各种分子和细胞机制，近年来已广泛采用组学方法。这篇综述总结了基因组学、转录组学、蛋白质组学、代谢组学的最新进展，以及它们在油菜籽非生物胁迫调节中的应用。突出显示了一些持续存在的瓶颈，需要适当关注以充分探索组学工具。更远，还解释了 CRISPR/Cas9 系统用于基因组编辑以协助分子育种开发耐非生物胁迫的油菜基因型的潜在前景。简而言之，整合组学、基因组编辑和快速育种的结合可以改变全球油菜籽的生产。
