Analyses of ribosomal ITS and chloroplast trnL-F sequences provide phylogenetic reconstruction for the festucoids (Poeae: Loliinae), a group of temperate grasses with morphological and molecular affinities to the large genus Festuca. Parsimony and Bayesian analyses of the combined ITS/trnL-F dataset show Loliinae to be monophyletic but unresolved for a weakly supported clade of 'broad-leaved Fe...
Divergence times and biogeographical analyses have been conducted within the Loliinae, one of the largest subtribes of temperate grasses. New sequence data from representatives of the almost unexplored New World, New Zealand, and Eastern Asian centres were added to those of the panMediterranean region and used to reconstruct the phylogeny of the group and to calculate the times of lineage-split...
جنس festuca l. با داشتن حدود 500 گونه یکی از بزرگ ترین جنس های علفی طایفه poeae و زیرطایفه loliinae می باشد. نتایج حاصل از این تحقیق حضور 19 گونه از جنس festuca متعلق به 4 زیرجنس و 6 بخش و2 زیربخش را در ایران نشان می دهد. از 19 تاکسون معرفی شده در این مطالعه، 7 گونه زیرجنس های drymanhele, schedonorus, leucopoa برگ-پهن و 12 تاکسون زیرجنس festuca به گونه های برگ-باریکfestuca تعلق دارند. همچنین با...
The species within the Lolium/Festuca grass complex have dispersed and colonized large areas of temperate global grasslands both naturally and by human intervention. The species within this grass complex represent some of the most important grass species both for amenity and agricultural use worldwide. There has been renewed interest by grass breeders in producing hybrid combinations between th...
Whole plastid genomes are being sequenced rapidly from across the green plant tree of life, and phylogenetic analyses of these are increasing resolution and support for relationships that have varied among or been unresolved in earlier single- and multi-gene studies. Pooideae, the cool-season grass lineage, is the largest of the 12 grass subfamilies and includes important temperate cereals, tur...
