چکیده

در این مطالعه وضعیت تاکسونومیک جنس Dictyota درسواحل جنوبی ایران مورد بررسی قرار گرفت. طبقه‌بندی این جنس در سطح گونه به‌دلیل تنوع بالای مورفولوژیک در پاسخ به شرایط محیطی و همچنین همپوشانی ویژگی‌های تشخیصی پیچیده و دشوار است. برای روشن شدن، اطلاعات مورفولوژیک را با داده‌های توالی‌های ژن‌های سیتوپلاسمی rbcL و psbA تلفیق کردیم. در این مطالعه گونه Dictyota acutiloba به عنوان یک رکورد جدید از منطقه شناسایی کرده و حضور Dictyota ciliolata را براساس مطالعات درخلیج فارس تأیید نمودیم. همچنین بررسی‌های ما نشان داد که گونه D. ciliolata دارای تنوع مورفولوژیک درون گونه‌ای بالایی می‌باشد.
