The ability of different germplasm to adapt to a saline-alkali environment is critical to learning about the tolerance mechanism of saline-alkali stress in plants. Flax is an important oil and fiber crop in many countries. However, its molecular tolerance mechanism under saline stress is still not clear. In this study, we studied morphological, physiological characteristics, and gene expression variation in the root and leaf in oil and fiber flax types under saline stress, respectively. Abundant differentially expressed genes (DEGs) induced by saline stress, tissue/organ specificity, and different genotypes involved in plant hormones synthesis and metabolism and transcription factors and epigenetic modifications were detected. The present report provides useful information about the mechanism of flax response to saline stress and could lead to the future elucidation of the specific functions of these genes and help to breed suitable flax varieties for saline/alkaline soil conditions.
不同种质适应盐碱环境的能力对于了解植物盐碱胁迫耐受机制至关重要。亚麻是许多国家重要的油料和纤维作物。然而，其在盐胁迫下的分子耐受机制仍不清楚。在本研究中，我们分别研究了油用亚麻和纤维用亚麻在盐胁迫下根和叶的形态、生理特征以及基因表达变化。检测到了由盐胁迫诱导的大量差异表达基因（DEG）、组织/器官特异性以及参与植物激素合成与代谢、转录因子和表观遗传修饰的不同基因型。本报告提供了有关亚麻对盐胁迫响应机制的有用信息，并可能有助于未来阐明这些基因的具体功能，以及培育适合盐碱土壤条件的亚麻品种。
