Abstract :
In this research, the taxonomic status of the genus Dictyota in southern coastlines of Iran was studied. Taxonomy of the genus at species levels is complicated and difficult due to the high morphological plasticity in response to environmental conditions and overlapping of diagnostic characters. In this study, we combined morphological information with cytoplasmic barcoding data from DNA rbcL and psbA. We identified Dictyota acutiloba as new record and also confirmed the presence of Dictyota ciliolata in the Persian Gulf and Gulf of Oman. Our studies showed D. ciliolata species has high inter-specific morphological diversity.

در اين مطالعه وضعيت تاكسونوميك جنس Dictyota درسواحل جنوبي ايران مورد بررسي قرار گرفت. طبقه‌بندي اين جنس در سطح گونه به‌دليل تنوع بالاي مورفولوژيك در پاسخ به شرايط محيطي و همچنين همپوشاني ويژگي‌هاي تشخيصي پيچيده و دشوار است. براي روشن شدن، اطلاعات مورفولوژيك را با داده‌هاي توالي‌هاي ژن‌هاي سيتوپلاسمي rbcL و psbA تلفيق كرديم. در اين مطالعه گونه Dictyota acutiloba به عنوان يك ركورد جديد از منطقه شناسايي كرده و حضور Dictyota ciliolata را براساس مطالعات درخليج فارس تأييد نموديم. همچنين بررسي‌هاي ما نشان داد كه گونه D. ciliolata داراي تنوع مورفولوژيك درون گونه‌اي بالايي مي‌باشد.
