Experimental studies were conducted for metabolomic profiling during seed germination and seedling development in Salicornia brachaita under saline conditions. The results revealed accumulation of sucrose, mannose, glycerol, methionine, tryptophan, glycerol, protocathechoic acid, and mannonic acid in germinating seeds. Abundance of rhamnose, glucose, glutamine, fructose, ornithine, quininic acid, proline and ketoglutaric acid were recorded during emergence of radical (EoR) and cotyledonary stage (CS) at 50% strength of seawater (SW) salinity. Higher levels of myo-inositol, ethanolamine, isoleucine and talose at 48 hours (hrs) of imbibition, EoR and CS stages; while glycine, tyrosine and turanose were so at CS stage only. Under 200 mM NaCl, richness of stearic acid, quercetin, leucine, erythritol and psicose were noted at 48 hrs of imbibition followed by EoR stage. Fructose, ornithine, mannitol, asparagine, mallic acid, glucose and citric acid were abundant at EoR whereas aminobutanoic acid, hexanedioic acid and tyramine were so at CS stage. Among detected metabolites maximum number of metabolites showed hits with amioacyl-tRNA biosynthesis pathway and the amino acid biosynthesis pathway had maximum impact during seedling development. Role of metabolic pathways (including amino acid metabolism) and differential expression of genes related to these pathways are suggested in meeting the energy needs for varied biological activities during seed germination and subsequent seedling development in S. brachiata.

对海蓬子种子萌发和幼苗发育过程中的代谢组学分析进行了实验研究在含盐条件下。结果表明，发芽种子中积累了蔗糖、甘露糖、甘油、蛋氨酸、色氨酸、甘油、原儿茶酸和甘露糖酸。在海水 (SW) 盐度强度为 50% 时，在自由基 (EoR) 出现和子叶阶段 (CS) 期间记录了鼠李糖、葡萄糖、谷氨酰胺、果糖、鸟氨酸、奎宁酸、脯氨酸和酮戊二酸的丰度。在吸入、EoR 和 CS 阶段 48 小时 (hrs) 时，肌醇、乙醇胺、异亮氨酸和塔罗糖水平较高；而甘氨酸、酪氨酸和松二糖仅在CS阶段如此。在 200 mM NaCl 下，在吸液 48 小时后的 EoR 阶段观察到硬脂酸、槲皮素、亮氨酸、赤藓糖醇和阿洛酮糖的丰富度。果糖、鸟氨酸、甘露醇、天冬酰胺、苹果酸、EoR 阶段葡萄糖和柠檬酸丰富，而 CS 阶段氨基丁酸、己二酸和酪胺丰富。在检测到的代谢物中，最大数量的代谢物显示与胺酰基-tRNA生物合成途径相关，并且氨基酸生物合成途径在幼苗发育过程中影响最大。代谢途径（包括氨基酸代谢）的作用以及与这些途径相关的基因的差异表达在满足种子萌发和随后的幼苗发育过程中各种生物活动的能量需求方面提出了建议。S.brachiata。
