菠菜是维生素的重要来源,矿物,和抗氧化剂。这些营养素使其美味,对人体健康有益。然而,菠菜中营养物质积累的遗传机制尚不清楚。在这项研究中,我们分析了叶绿素a的含量,叶绿素b,草酸盐,硝酸盐,粗纤维,可溶性糖,锰,铜,和铁在62种不同的菠菜中。此外,3,356,182高质量,使用重测序发现单核苷酸多态性,并用于全基因组关联研究.共发现2077个基因座与营养元素的浓度显着相关。数据挖掘确定了这些区间中四个性状的关键基因:叶绿素,草酸盐,可溶性糖,Fe。我们的研究提供了对营养变异的遗传结构的见解,并促进菠菜育种以获得良好的营养。
Spinach is a significant source of vitamins, minerals, and antioxidants. These nutrients make it delicious and beneficial for human health. However, the genetic mechanism underlying the accumulation of nutrients in spinach remains unclear. In this study, we analyzed the content of chlorophyll a, chlorophyll b, oxalate, nitrate, crude fiber, soluble sugars, manganese, copper, and iron in 62 different spinach accessions. Additionally, 3,356,182 high-quality, single-nucleotide polymorphisms were found using resequencing and used in a genome-wide association study. A total of 2077 loci were discovered that significantly correlated with the concentrations of the nutritional elements. Data mining identified key genes in these intervals for four traits: chlorophyll, oxalate, soluble sugar, and Fe. Our study provides insights into the genetic architecture of nutrient variation and facilitates spinach breeding for good nutrition.
