چکیده
گیاهAloe barbadensis Mill. گیاهی چندساله، تک­لپه، گوشت­دار از تیرۀ Aloaceae است. در این مطالعه، تنوع سوماکلونال گیاهان باززایی­شدۀ A. barbadensis بعد از چهار واکشت و انتقال به گلدان تحت بررسی قرار گرفت. ژنوم 40 گیاه باززایی­شده استخراج و تنوع ژنتیکی با استفاده از 20 نشانگر SPAR شامل پرایمرهایRAPD وISSR بررسی شد. همچنین، میزان ژل حاصل از گیاهان باززادۀ آلوئه ­ورا محاسبه گردید. میانگین درصد پلی­مورفیسم، اندیس­شانون، تنوع ژنتیکی Nei’s و تعداد الل ­های مؤثر براساس داده ­های RAPD، بالاتر از پارامترهای ژنتیکی به­ دست­ آمده از داده ­های ISSR بود. خوشه­ بندی NJ و ساختار ژنتیکی براساس نمودار STRUCTURE بر پایۀ نشانگرهای تحت مطالعه توانستند افراد را به خوشه­ های جداگانه تقسیم کنند. تحلیل AMOVA نیز نشان­دهندۀ تمایز ژنتیکی بین گروه­ ها در سطح معنی ­داری (P=0.01) بوده است و تأییدکنندۀ تفرق گروه ­های حاصل از تجزیۀ خوشه­ ای داده ­های مولکولی است. میزان تولید ژل در گروه­ های ایجاد­شده براساس تحلیل تجزیۀ خوشه­ ای با استفاده از آزمون تحلیل واریانس (ANOVA) بررسی شد که تفاوت معناداری (P=0.746) بین مقدار ژل در چهارگروه مشاهده نشد. نتایج این مطالعه توانست تغییرات سوموکلونال در سطح ژنوم با استفاده از نشانگرهای مولکولی را در میان گیاهان باززایی­ شده آلوئه نشان دهد، درحالی­که میزان ژل تولیدی در میان این گیاهان تغییر معناداری نشان داد.

چکیده English

Aloe barbadensis is perennial, monocotyledonous, fleshy plant belongs to Aloaceae family. In this study, somoclonal variations of regenerated A. barbadensis plants were investigated. The plantlets of forth subculture transferred to the soil for further study. The genomic DNAs of 40 regenerated plantlets were extracted and genetic variations were studied using SPAR markers including RAPD and ISSR primers. The amounts of Aloe gel also were extracted from regenerated A. vera plants. Average percentage of polymorphism, Shannon index, Nei's genetic diversity and number of effective alleles based on RAPD data were higher than genetic parameters obtained from ISSR data. NJ cluster and STRUCTURE plot based on molecular markers grouped regenerated plants to distinct clusters. AMOVA analysis also showed a significant (P = 0.01) genetic distinction between studied groups. This result also confirmed differentiation of regenerated plants. The amount of Aloe gel in the four groups (based on clustering method) was compared by using analysis of variance (ANOVA). The results showed no significant (P = 0.746) differences between the amount of gel in four group. In total, our findings showed somaclonal variations on genomic level while no significant differences were observed in amount of gel among regenerated Aloe plantlets.
