Abstract

In a taxonomic revision of the genus Scutellaria in Iran, the specimens identified as Sc. multicaulis Boiss. in the herbarium of Research Institute of Forests & Rangelands (TARI) as well as specimens belonging to the newly collected materials were examined and sampled for DNA sequencing by using nrDNA ITS and cpDNA trnL-F as molecular markers. Morphological variations such as flowers color, leaf shape and indumentum were diagnostic characters in the studied specimens. Accordingly, specimens could be divided into two different morphological groups. Sampling of representatives of each morphological group was carried out for DNA sequencing. The results showed differences in sequences of determined groups. Based on the results of this study, three new taxa are recognized and described.

Abstract [Persian]

در مرور تاکسونومیکی جنس Scutellaria در ایران، نمونه‌های شناسایی شده تحت نام Scutellaria multicaulis Boiss. در هرباریوم مؤسسه تحقیقات جنگلها و مراتع کشور (TARI) و همچنین نمونه‌های مربوط به جمع‌آوری‌های جدید مورد بررسی قرار گرفتند و جهت تعیین توالی DNA با استفاده از مارکرهای مولکولی هسته‌ای ITS و کلروپلاستی trnL-F نمونه برداری شدند.
تنوع ریخت‌شناسی مانند رنگ گل‌ها و شکل برگ‌ها و نوع کرک‌ها در نمونه‌های مورد بررسی مشاهده گردید. بر اساس رنگ گل‌ها نمونه‌ها به دوگروه مختلف تقسیم شدند. تعیین توالی DNA نمایندگانی از هر گروه انجام شد و نتایج به دست آمده تفاوت‌هایی را در بین گرو‌ه‌های تعیین شده نشان داد. بر اساس نتایج حاصل سه آرایه جدید شناسایی و شرح داده شدند.
