Метаболомы литоральных водорослей-макрофитов Белого моря

Водоросли литорали обитают в жёстких условиях, подвергаясь действию многочисленных абиотических факторов. В их число входят изменение солёности, оводнённости, температуры окружающей среды и освещённости. При этом на литорали обитают водоросли из различных эволюционных линий – зелёной, красной и бурой. Благодаря различному происхождению организмы разных таксонов могут иметь различные механизмы адаптации к этим экстремальным условиям, которые у прикреплённых организмов представлены изменением биохимического состава. В данной работе с помощью метаболомного анализа были исследованы водоросли 9 видов, Ulva intestinalis, Cladophora fracta, Cladophora rupestris, Palmaria palmata, Odonthalia dentata, Fucus serratus, Fucus disthicus, Ascophyllum nodosum и Pelvetia canalliculata, относящиеся к зелёным, красным и бурым линиям. С помощью различных методов кластеризации были показаны группы, в которые объединяются образцы по полученным данным, а также были выявлены метаболиты, содержание которых свойственно каждой из эволюционных групп.
