Phylogeny of Rhaponticum (Asteraceae, Cardueae-Centaureinae) and related genera inferred from nuclear and chloroplast DNA sequence data: taxonomic and biogeographic implications.
BACKGROUND AND AIMS The precise generic delimitation of the Rhaponticum group is not totally resolved. The lack of knowledge of the relationships between the basal genera of Centaureinae could imply that genera whose position is as yet unresolved could belong to the Rhaponticum group. On the other hand, the affinities among the genera that are considered as members of this group are not well kn...
متن کاملNovelties in Cardueae (Asteraceae)
The current investigations suggest the segregation of Jurinea cartilaginea from Jurinea, and its placement among Centaureinae. Molecular studies, based on the nuclear ribosomal internal transcribed spacers (nrITS), chromosome number data and pollen morphology, support the morphological results. Based on these results, J. cartilaginea is related to and, therefore, transferred to the genus Karvan...
متن کاملنکاتی در مورد آرایه شناسی Cousinia sect. Haussknechtianae (Asteraceae; Cardueae)
آرایه‌شناسی Cousinia sect. Haussknechtianae (Asteraceae; Cardueae) مورد بازنگری قرار گرفت. گونه‌های این بخشه پراکنش محدودی در مناطق مرتفع کوهستانی مرکز، جنوب غربی و غرب ایران و شمال شرقی عراق دارند. به دلیل موسم گلدهی دیرهنگام و پراکندگی آنها در مناطق دورافتاده کوهستانی، این گونه‌ها کمتر شناخته شده‌اند. به دلیل بررسی نمونه‌های گیاهی زیادی که در سال‌های اخیر از کوه‌های زاگرس جمع آوری شده است، ...
متن کاملReconstructing the evolution and biogeographic history of tribe Cardueae (Compositae).
UNLABELLED PREMISE OF THE STUDY Tribe Cardueae (thistles) forms one of the largest tribes in the family Compositae (2400 species), with representatives in almost every continent. The greatest species richness of Cardueae occurs in the Mediterranean region where it forms an important element of its flora. New fossil evidence and a nearly resolved phylogeny of Cardueae are used here to reconst...
متن کاملThe Genera of Asteraceae Endemic to Mexico and Adjacent Regions
The flora of Mexico includes about 119 endemic or nearly endemic genera of Asteraceae. In this study, the genera are listed and their distribution patterns among the floristic provinces of Mexico analyzed. Results indicate strong affinities of the endemic genera for mountainous and arid or semiarid regions. Since its first appearance in Mexico, the Asteraceae diversified into these kinds of hab...
