Untargeted metabolomics was employed to analyze relative abundance variations and regulatory mechanisms of organic acids in root exudates. The results demonstrated that salt stress significantly decreased the secretion of organic acids including 1-hydroxy-2-naphthoic acid, succinic acid, homogentisic acid, phenylpyruvic acid and indolelactic acid (P<0.05), while significantly enhancing the secretion of phenoxyacetic acid (P<0.05). However, no significant effects on the secretion of 3-hydroxybutyric acid and shikimic acid. Principal coordinate analysis (PCoA) revealed significant differences in root-secreted organic acid profiles between control and salt-stressed treatments (mild, moderate and severe salinity) (P<0.05). Correlation analysis demonstrated that soil salinity, electrical conductivity, water content, and pH were key determinants influencing root organic acid secretion. Path analysis further revealed that salt stress promoted phenoxyacetic acid secretion through soil salinization-mediated suppression of root morphological traits. These findings provide a theoretical basis for the in-depth analysis of the physiological mechanisms of plant salt tolerance., authors=ZHANG Ran1,2,3, YANG Liang1,2,3, LI Dan1,2,3, LI Yan-jie1,2,3, LU

journalTitle=草地学报, columnName=研究论文, runingTitle=null, highlight=null, articleAbstract=为探究长穗偃麦草(Thinopyrum ponticum)根系分泌有机酸对盐胁迫的响应及其与根系性状和根际土壤理化性质的关系,设置对照、轻度、中度和重度(土壤含盐量分别为0%,0.2%,0.4%,0.6%)盐胁迫处理,利用非靶向代谢组学技术,分析长穗偃麦草根系分泌有机酸的相对丰度及其变化机制。结果表明,盐胁迫显著降低1-羟基-2-萘酸、琥珀酸、尿黑酸、苯丙酮酸及吲哚乳酸有机酸的分泌量(P<0.05),显著促进苯氧基乙酸的分泌(P<0.05),但对3-羟基丁酸和莽草酸的分泌无显著影响。主坐标分析显示,轻度、中度和重度盐胁迫处理的根系分泌有机酸与对照相比差异显著(P<0.05)。相关性分析表明,土壤盐度、电导率、含水量和pH是影响根系分泌有机酸的重要因素。路径分析结果表明,盐胁迫通过显著增加土壤盐分,抑制根系性状进而促进苯氧基乙酸的分泌。上述结果为深入解析植物耐盐生理机制提供理论依据。,

To elucidate the responses of organic acids secreted by the roots of Thinopyrum ponticum under salt stress and their interactions with root traits and rhizosphere soil physicochemical properties, a controlled experiment with four salinity treatments was established: control, mild, moderate and severe salt stress (with soil salt contents of 0%, 0.2%, 0.4%, and 0.6% w/w, respectively). Untargeted metabolomics was employed to analyze relative abundance variations and regulatory mechanisms of organic acids in root exudates. The results demonstrated that salt stress significantly decreased the secretion of organic acids including 1-hydroxy-2-naphthoic acid, succinic acid, homogentisic acid, phenylpyruvic acid and indolelactic acid (P<0.05), while significantly enhancing the secretion of phenoxyacetic acid (P<0.05). However, no significant effects on the secretion of 3-hydroxybutyric acid and shikimic acid. Principal coordinate analysis (PCoA) revealed significant differences in root-secreted organic acid profiles between control and salt-stressed treatments (mild, moderate and severe salinity) (P<0.05). Correlation analysis demonstrated that soil salinity, electrical conductivity, water content, and pH were key determinants influencing root organic acid secretion. Path analysis further revealed that salt stress promoted phenoxyacetic acid secretion through soil salinization-mediated suppression of root morphological traits. These findings provide a theoretical basis for the in-depth analysis of the physiological mechanisms of plant salt tolerance.
