[ 2 ] - Cladistic analysis of the tribe Bromeae (Poaceae) based on morphological characters in Iran
This study is concerned with the morphological cladistic analysis of monotypic tribe Bromeae including the genus Bromus. To characterize taxonomic circumscription of the genus, its species and sectional relationships of 39 taxa belonging to 6 sections and 2 outgroups were evaluated. Based on the heuristic search for 26 morphologhical informative characters, Maximum Parsimony approach was used for…
[ 3 ] - AN OVERVIEW OF THE PHYLOGENETIC RELATIONSHIPS OF BROMUS PUMILIO (POACEAE) AND ALLIES BASED ON nrDNA ITS AND trnL-F SEQUENCES
According to various taxonomic treatments, Bromus has been divided into 8 to 9 sections, subgenera or even separate genera. The relationship of Bromus pumilio (syn.: Boissiera squarrosa) with other species of Bromus has long been a matter of dispute. To clarify this problem, the nuclear ribosomal DNA ITS and chloroplast DNA trnL-F sequences for 31 and 28 species respectively were used to reconstr…
