1 UNDERSTANDING NLRS FOR BETTER RESISTANCE

Understanding the evolutionary history and variations in NLR disease resistance genes is important to protect Brassica vegetable and oilseed crops from damage caused by disease. Zhang et al. (https://doi.org/10.1002/tpg2.20060) show that duplications at the genome and sub‐genome levels, selection from pathogens and recombination within Brassica populations have shaped the highly duplicated and diverse NLR patterns in Brassica genomes. The number and clustering pattern of NLR genes in Brassica vegetable and canola genomes were compared to understand the evolutionary patterns of the NLR genes. Studies on the identification of disease resistance genes through comparative approaches were highlighted to address the importance of NLR duplication and diversification on strengthening disease resistance in Brassicas. This review is crucial to help gain insights into their function and inform the identification of resistance genes for breeding of resistant lines.

1更好地理解NLRS

了解NLR抗病基因的进化历史和变异对于保护芸苔属植物和油料作物免受疾病造成的损害很重要。张等。（https://doi.org/10.1002/tpg2.20060）表明，在芸苔属种群中，基因组和亚基因组水平的重复，病原体的选择和重组已形成了芸苔属基因组中高度重复和多样化的NLR模式。比较了芸苔属植物和油菜基因组中NLR基因的数量和聚类模式，以了解NLR基因的进化模式。强调了通过比较方法鉴定抗病基因的研究，以解决NLR复制和多样化对加强甘蓝型油菜抗病性的重要性。
