Во всем мире она ис­ пользуется в качестве продукта питания, применяется в медицинских целях, а также идет на удобрения и фураж. В статье приводятся результаты первого иссле­ дования морфологических, генетических и биохими­ ческих различий между четырьмя видами водорослей рода Ulva, образцы которых были собраны в Восточной бухте города Александрии (Египет). При исследовании морфологии таллуса были выявлены значительные видоспецифические различия, но данных для того, чтобы отделить один вид от другого в пределах одного и того же рода, недостаточно, поскольку на указанный признак влияют как экологические факторы, так и ста­ дия развития растения. Генетические различия между исследованными видами ульвы анализировали с помо­ щью метода случайно амплифицируемой полиморфной ДНК (RAPD). Анализ дендрограммы показал, что наибо­ лее близки друг к другу виды U. lactuca и U. compressa, тогда как U. fasciata является видом, отдаленным как от U. lactuca, так и от U. compressa. В то же время было по­ казано, что U. linzea является уникальным видом. Разли­ чия, выявленные между видами ульвы методом RAPD, говорят о возможности получения «фингерпринта» для индивидуальных водорослей при использовании лишь небольшого числа праймеров. На основе своего биохи­ мического состава (белкового, углеводного, липидного и пигментного) собранные виды были разбиты на две группы: в одну вошли U. fasciata и U. lactuca, а в другую – U. compressa и U. linzea.</p></abstract><trans-abstract xml:lang="en"><p>Ulva is most common green seaweed in Egypt coast, it used as a source of food, feed, medicines and fertilizers in all the world. This study is the first time to investigate the morphological, genetic and biochemical variation within four Ulva species collected from Eastern Harbor, Alexandria. The morphology description of thallus showed highly variations according to species, but there is not enough data to make differentiation between species in the same genus since it is impacted with environmental factors and development stage of seaweeds. Genetic variations between the tested Ulva spp. were analyzed using random amplified polymorphic DNA (RAPD) analyses which shows that it would be possible to establish a unique fingerprint for individual seaweeds based on the combined results generated from a small collection of primers. The dendrogram showed that the most closely species are U. lactuca and U. compressa, while, U. fasciata was far from both U. lactuca and U. compressa. Meanwhile, U. linzea is showed to be a unique species. The biochemical composition (e.g. protein, carbohydrate, lipid and pigment composition) of the collected Ulva spp. grouped the collected Ulva spp. into two groups (U. fasciata and U. lactuca) and other (U. compressa and U. linzea).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>морфологический признак</kwd><kwd>генетиче­ ский</kwd><kwd>биохимический</kwd><kwd>RAPD</kwd><kwd>ульва</kwd></kwd-group><kwd-group xml:lang="en"><kwd>morphological character</kwd><kwd>genetic</kwd><kwd>biochemical</kwd><kwd>RAPD</kwd><kwd>Ulva spp</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Abbott I.A., Hollenberg I.G.
