34 گونه از جنس درمنه در ایران گزارش شده است که از لحاظ پراکنش، تراکم و پوشش مهمترین جنسهای گیاهی در کشور محسوب میشوند. از آنجا که هنوز سیستم کلی و جامعی برای طبقهبندی و فیلوژنی آن ارائه نشده است، در این پژوهش سعی شد تا با بررسی تنوع کلروپلاستی و روابط فیلوژنتیکی گونههای درمنه و مقایسۀ آنها با گونههای دیگر موجود در جهان، مسیر تکاملی آنها شناسایی و قرابت ژنتیکی آنها مشخص شود تا از این ...
The taxonomy and systematics of Urgineoideae (Hyacinthaceae) have been controversial in recent decades, with contrasting taxonomic treatments proposed based on preliminary partial studies that focused morphology and/or solely plastid DNA sequence data. Some authors recognized only two genera, a very broadly conceived Drimia, while others accepted several genera that, although better defined mor...
Phylogenetic relations among 12 wild species of almonds, one cultivated almond and one species of peach were investigated by using of ITS1-5.8S rDNA-ITS2 sequences and trnL region of chloroplast DNA. To do this, maximum-parsimony and neighbor joining analysis adopted. Results of ITS data showed that studied species of Prunus only divided in two groups but incapable to separate different section...
جنس Myosotis دارای پانزده گونه در ایران است و ویژگی تشخیصی آن میوه صاف، سیاه و براق می‌باشد. به منظور نشان دادن موقعیت فیلوژنتیکی Myosotis، 14گونه از آن به همراه گونه‌هایی ازقبیله Cynoglosseae s. l. با استفاده از مارکرکلروپلاستیrpl32-trnL و همچنین توالی ترکیبی cpDNArpl32-trnLUAG-nrDNAITS، به دو روش پارسیمونی و بایسین مورد بررسی قرار گرفتند. نتایج، تک تباری جنس Myosotis را تایید نمود. همچنین ن...
Eight new rbcL DNA sequences and 15 new sequences from the 5' end of the chloroplast ndhF gene were obtained from representative Dipsacales and outgroup taxa. These were analyzed in combination with previously published sequences for both regions. In addition, sequence data from the entire ndhF gene, the trnL-F intergenic spacer region,the trnL intron,the matK region, and the rbcL-atpB intergen...
The Arabidopsis arenosa complex is closely related to the model plant Arabidopsis thaliana. Species and subspecies in the complex are mainly biennial, predominantly outcrossing, herbaceous, and with a distribution range covering most parts of latitudes and the eastern reaches of Europe. In this study we present the first comprehensive evolutionary history of the A. arenosa species complex, cove...
The ability to discriminate all species is the ultimate target in barcoding. The Mediterranean basin is a center of origin for legumes and thus they have played a key role in feeding the Mediterranean population. It is also a region with important protected designation of origin and protected geographical indication legumes that provide income in rural areas. We evaluated the use of two ch...
The subtribe Eritrichiinae belongs to tribe Rochelieae (Borginaceae; Cynoglossoideae) which is composed of about 200 species in five genera including Eritrichium, Lappula, Hackelia, Lepechiniella, and Rochelia. The majority of the species are annual and grow in xeric habitats. The genus Lappula as an arid adapted and the second biggest genus...
Melilotus, an annual or biennial herb, belongs to the tribe Trifolieae (Leguminosae) and consists of 19 species. As an important green manure crop, diverse Melilotus species have different values as feed and medicine. To identify different Melilotus species, we examined the efficiency of five candidate regions as barcodes, including the internal transcribed spacer (ITS) and two chloroplast loci...
