Isozyme variation and phylogenetic relationships in Vicia subgenus Cracca (Fabaceae).
BACKGROUND AND AIMS The phylogenetic relationships among 27 vetch species belonging to the subgenus Cracca of the genus Vicia were studied in comparison with three species of Lathyrus section Lathyrus on the basis of isozyme variation. METHODS Isozymes encoded by 15 putative loci of ten enzymes were resolved by polyacrylamide gel electrophoresis and isozyme variation was analysed by using par...
متن کاملبررسی سیتوتاکسونومی جنس Vicia از تیره Fabaceae در ایران
برای بررسی سیتوتاکسونومی جنس Vicia در ایران، از 40 تاکسون مختلف از 13 بخش جهت مطالعه کروموزوم‌ها در مرحله متافاز میتوز استفاده شد. کمترین عدد دیپلوئید مشاهده شده برابر با 10 و بیشترین برابر با 28 بود. در میان اعداد دیپلوئید شمارش شده 3 عدد پایه کروموزومی در تاکسون‌های جنس Vicia در ایران (x=5, 6, 7) مشاهده شد. بر این پایه، این جنس دارای دو سطح دیپلوئیدی و تتراپلوئیدی در ایران است. در تاکسون‌های ...

In such cases, it is reasonable to describe commonly accepted rules, opinions, and practices in a general way so as to illustrate how bioethical questions are being managed. This article describes certain goals and practices r...
متن کاملThe Evolution of Vicia ramuliflora (Fabaceae) at Tetraploid and Diploid Levels Revealed with FISH and RAPD
Vicia ramuliflora L. is a widely distributed species in Eurasia with high economic value. For past 200 years, it has evolved a tetraploid cytotype and new subspecies at the diploid level. Based on taxonomy, cytogeography and other lines of evidence, previous studies have provided valuable information about the evolution of V. ramuliflora ploidy level, but due to the limited resolution of tradit...
متن کاملTaxonomy and phylogeny of the genus Crotalaria (Fabaceae): An overview
Crotalaria (Fabaceae) is the largest legume genus represented by 81 species in India. The existing sectional classification for Crotalaria in India is based on morphological characters and is not completely supported by the molecular phylogenetic studies. Molecular systematic studies of the Indian sections Crotalaria and Calycinae have enabled merging of both these sections into Calycinae. Trif...
