The role of morphological data in phylogeny reconstruction.

Phylogeny of some species of Astragalus (Fabaceae) based on morphological data

The phylogenetic relationships among 39 species belonging to 12 sections of Astragalus from Iran were studied on the basis of 29 morphological characters. The cladistics analysis of the morphological data was performed using PAUP* 4.0b10 program. The obtained data were compared with the molecular systematics data obtained from nuclear DNA ITS. In contrast with previous molecular systematic stud...

Molecular phylogeny and taxonomy of species of Cousinia section Stenocephalae (Asteraceae) in NE of Iran

In this study, the phylogeny and morphological variation of 6 species of the genus Cousinia sect. Stenocephalae, i.e., C. hypopolia, C. decipiens, C. esfandiarii, C. renominata, C. stahliana and C. daryoushiana, distributed in NE regions of Iran, were investigated. ITS, ETS and rpl32-trnL (UAG) sequences for 12 species (17 specimens) were generated. Phylogenetic interspecies relationships were ...

Running Head : Points of View The Role of Morphological Data in Phylogeny Reconstruction

Morphology's role in phylogeny reconstruction: perspectives from paleontology.

A recent article by Scotland et al. (2003; hereafter referred to as SEA) purporting to examine the value of morphological data in phylogeny reconstruction has been received critically by several systematists (Jenner, 2004; Wiens, 2004). As paleontologists—and in an area of systematics restricted solely to morphological data—we take exception to many of the arguments put forward by SEA and feel ...

Phylogeny of Onobrychis sect. Hymenobrychis (Fabaceae) based on chloroplast DNA sequence data

Phenetic analysis of morphological characters in different species of Onobrychis Miller sect. Hymenobrychis DC. (Fabaceae), classified them in two main groups based on corolla features. To determine the phylogenetic relationships among the 13 species, chloroplast DNA sequences were used. Analysis of these data resulted in a well-resolved and well-supported phylogeny. Phylogenies generated by ma...

Phylogeny of Phytophthora and Phytopythium species associated with rice in Fars province (Iran)

In order to investigate the Oomyceteous species of the rice paddy fields of Fars province (Iran), during 2013–15, infected roots and crowns together with soil around seedlings and irrigation water were sampled. Based on the morphological, morphometric and physiological studies along with phylogenetic analyses of internal transcribed spacer sequences based on neighbor joining method, two Phytoph...
