Abstract

The issue of the formation of the compound composition of low-molecular-weight organic compounds in aquatic macrophytes, which make up their low-molecular-weight metabolism, has hardly been studied when introducing them into new habitats. The study aims to compare the component composition of the low-molecular-weight metabolome of sago pondweed (Potamogeton pectinatus L.) on the low-molecular-weight organic compounds contained in the essential oil from the invasive population in the Lake Ladoga and the populations from the native range in Astrakhan Region, Russia. Gas chromatography–mass spectrometry was the major research method. Upon the invasion of P. pectinatus into Lake Ladoga, there was a change in the content of various groups of low-molecular-weight organic compounds in the essential oil and a change in the complex of major components. Fatty acids (29.3–40.0%) and ketones (14.5–18.5%) prevailed in the low-molecular-weight metabolome of sago pondweed in the lakes of the native range. Ketones (27.4%) and aldehydes (18.1%) were the main groups in this species inhabiting Lake Ladoga. About a third of the compounds in the composition of the low-molecular-weight metabolome were specific both to the invasive population of the sago pondweed in the Lake Ladoga and to the population from the lakes of the native range. The plasticity of the metabolism of P. pectinatus allows it to adapt to a wide spectrum of abiotic conditions and different biological environments and to settle in new habitats, primarily those under anthropogenic impact.

与原生境种群相比,拉多加湖外来物种Potamogeton pectinatus L.的低分子量代谢组的变化

摘要

当将水生植物中的低分子量有机化合物引入新的生境时,几乎没有研究过构成其低分子量代谢的低分子量有机化合物的化合物组成的问题。该研究旨在比较西米草(Potamogeton pectinatus L.)的低分子量代谢组与拉多加湖入侵种群和种群中精油中所含低分子量有机化合物的成分组成。来自俄罗斯阿斯特拉罕地区的原产地。气相色谱-质谱法是主要的研究方法。入侵果蝇后进入拉多加湖,精油中各种低分子量有机化合物的含量发生了变化,主要成分的复合物也发生了变化。脂肪酸(29.3–40.0%)和酮(14.5–18.5%)在本地范围的湖泊中的西米草的低分子量代谢组中占主导地位。酮(27.4%)和醛(18.1%)是居住在拉多加湖中的主要物种。在低分子量代谢组中,约三分之一的化合物既对拉多加湖中西米草的侵入性种群又对本地范围的湖泊的种群具有特异性。果蝇对虾代谢的可塑性 使其适应各种非生物条件和不同的生物环境,并适应新的栖息地,主要是在人为影响下。
