is an important vegetable, and its quality is affected by salt stress. () contribute to plant development and tolerance to salt stress. In this study, 35 genes were identified from a genome database for , including 9 , 5 , and 21 genes. Furthermore, in , the expression levels of most genes were higher at a low salinity level (50 or 100 mM NaCl) than in the control or 200 mM NaCl treatment. Levels of most genes were elevated in the stem. Moreover, was homologous to , which is involved in the regulation of sodium homeostasis and salt stress response. After overexpression in , seed germination was better, and the flowering time was earlier than that of wild-type plants. Additionally, the overexpression of in improved salt tolerance. These results reveal the roles of genes under salt stress and provide valuable information on this gene family in amaranth.
是一种重要的蔬菜，其品质受盐胁迫影响。（）有助于植物发育和耐盐胁迫。在本研究中，从的基因组数据库中鉴定出35个基因，包括9个、5个和21个基因。此外，在中，大多数基因在低盐度水平（50或100 mM NaCl）下的表达水平高于对照或200 mM NaCl处理。大多数基因在茎中的水平升高。此外，与参与钠稳态调节和盐胁迫反应的同源。在中过表达后，种子萌发更好，开花时间比野生型植物更早。此外，在中过表达提高了耐盐性。这些结果揭示了盐胁迫下基因的作用，并为苋菜中该基因家族提供了有价值的信息。
