Centaurea revisited: A molecular survey of the Jacea group.
BACKGROUND AND AIMS The genus Centaurea has traditionally been considered to be a complicated taxon. No attempt at phylogenetic reconstruction has been made since recent revisions in circumscription, and previous reconstructions did not include a good representation of species. A new molecular survey is thus needed. METHODS Phylogenetic analyses were conducted using sequences of the internal ...
متن کاملCHROMOSOME COUNTS IN SOME MOSSES OF IRAN
Cytological information is absolutely lacking for the Iranian moss flora (Bryophytes). The present research, dealing with cytological studies on the following five species (including two expressions and one variety) of Iranian mosses, namely, Amblystegium riparium (Hedw.) B.S.G. “brevipes” expression(n=20), A. riparium (Hedw.) B.S.G. “pennellii” expression (n=9, 9+m, 9+2m), A. serpens (Hedw.) B...
متن کاملNew chromosome counts in some plant species from east and south-east Iran
In this study, we investigated the chromosome numbers of some endemic species distributed in East and South-East Iran. The mitotic chromosome counts were presented for the first time for six species in three angiosperm families including: Linaria iranica (2n=12), Nanorrhinum campyloceras (2n=18), Chaenorhinum grossecostatum (2n=24) (Plantaginaceae), Gaillonia bruguieri (Rubiaceae) (2n=22), Nepe...
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 کاملEffective Long-Distance Pollen Dispersal in Centaurea jacea
BACKGROUND Agri-environment schemes play an increasingly important role for the conservation of rare plants in intensively managed agricultural landscapes. However, little is known about their effects on gene flow via pollen dispersal between populations of these species. METHODOLOGY/PRINCIPAL FINDINGS In a 2-year experiment, we observed effective pollen dispersal from source populations of C...
