This work aims to analyze the phylogeography of Schizolobium parahyba(Fabaceae), which includes two varieties with a disjunct distribution, from Southern Brazil to Central America. Neotropical rain forests, focus on four largest wet forests: Atlantic forest, Amazonian forests, Andean forest and Central America forest. The genetic diversity and differentiation of populations among S. parahyba po...
Chloroplast trnL-F sequence data, nuclear ribosomal internal transcribed spacer (ITS) sequence data, and morphology were used to analyze phylogenetic relationships among members of the subtribe Strobilanthinae. Parsimony and maximum likelihood analyses of trnL-F indicate that the Strobilanthinae are a monophyletic group. While parsimony analysis of ITS recovers a nonmonophyletic subtribe, maxim...
Aneura pinguis is a thalloid liverwort species with broad geographical distribution. It is composed of cryptic species, however, the number of cryptic species within A. pinguis is not known. Five cpDNA regions (matK, rbcL, rpoC1, trnH-psbA and trnL-trnF) and the entire nuclear ITS region were studied in 130 samples of A. pinguis from different geographical regions. The relationships between the...
BACKGROUND AND AIMS Rhododendron (Ericaceae) is a large woody genus in which hybridization is thought to play an important role in evolution and speciation, particularly in the Sino-Himalaya region where many interfertile species often occur sympatrically. Rhododendron agastum, a putative hybrid species, occurs in China, western Yunnan Province, in mixed populations with R. irroratum and R. del...
Few studies have addressed the phylogeography of species of the Cerrado, the largest savanna biome of South America. Here we aimed to investigate the phylogeographical structure of Dalbergia miscolobium, a widespread tree from the Cerrado, and to verify its concordance with plant phylogeographical and biogeographical patterns so far described. A total of 287 individuals from 32 populations were...
Historic events such as the uplift of mountains and climatic oscillations in the Quaternary periods greatly affected the evolution and modern distribution of the flora. We sequenced the trnL-trnF, ndhJ-trnL and ITS from populations throughout the known distributions of O. longilobus and O. taihangensis to understand the evolutionary history and the divergence related to the past shifts of habit...
In this study, 3 haplotypes were found in populations of Phellodendron amurense based on two combined cpDNA regions (psbA-trnH and trnT-trnL). Nucleotide diversity haplotype 0.43×10 -3 0.41, respectively at the level species. The AMOVA revealed that only 8.53% variation was explained by differences among geographical groups, whereas inter-population intrapopulation 18.32% 71.35% variation, resp...
Within the tribe Abildgaardieae, the relationships between Fimbristylis and its relatives have not been certain, and the limits of Fimbristylis have been unclear, with Bulbostylis and Abildgaardia variously combined with it and each other. The relationships and limits of tribes Abildgaardieae and Arthrostylideae and their genera were evaluated across 49 representative species using parsimony an...
Melilotus comprises 19 species, while the phylogenetic relationships between species remain unclear. In the present work, three chloroplast genes, rbcL, matK, trnL-F, and one nuclear region, ITS (internal transcribed spacer) belonging to 48 populations of 18 species of Melilotus were sequenced and phylogenetic trees were constructed to study their interspecific relationships. Based on the phylo...
گیاه Zannichellia L.(Potamogetonaceae) یک جنس جهان وطن است که در اکوسیستمهای آبی ایران به طور گسترده پراکنش دارد. آخرین بررسی تاکسونومیکی این جنس مربوط به فلورا ایرانیکا در سال 1971 به همراه بعضی تغییرات اخیر صورت گرفته در فلور ایران است. هدف از این پژوهش، بررسی تاکسونومیکی جدید این جنس در ایران براساس مطالعات پراکنش جغرافیایی، ریختشناسی و مطالعات مولکولی (با استفاده از نشانگرهای ITS ، PHYB، ...
