Molecular evidence for allopolyploid speciation and a single origin of the narrow endemic Draba ladina (Brassicaceae).
Draba ladina (Brassicaceae) is a small alpine flower endemic to the Swiss Alps. It occurs exclusively at elevations between 2600 and 3000 m and is restricted to less than a dozen mountains in the Lower Engadin. Morphological characters and polyploidy suggest a hybrid origin. Potential diploid progenitor species are distributed widely and often occur sympatrically. To study the evolutionary hist...
متن کاملMolecular phylogeny and intra- and intercontinental biogeography of Calycanthaceae.
Based on nuclear and chloroplast sequences we resolve species relationships in Calycanthaceae and develop a biogeographic hypothesis that explains their intercontinental disjunctions and intra-continental diversification in eastern Asia. Fossil-calibrated penalized likelihood and Bayesian divergence time estimates indicate that the Northern Hemisphere Calycanthus and Chimonanthus diverged from ...
متن کاملNano-Metal oxides induced sulforaphane production and peroxidase activity in seedlings of Lepidium draba (Brassicaceae)
Effects of different concentrations [0, 1, 5, 10, 20 and 40 mgL-1] of Fe3O4 and CuO nano-particles (nFe3O4 and nCuO) were investigated on sulforaphane (SFN) production level in 7-day-old seedlings of Lepidium draba at different time intervals (8 and 16 hrs). According to the results, the influence of the particles on SFN contentdepends on nano-particle (NP) concentrations, time of treatment as ...
متن کاملInvasion of Lepidium draba (Brassicaceae) in the western United States: distributions and origins of chloroplast DNA haplotypes.
Advances in phylogeography are of great value for understanding the population structure and origins of invasive genotypes. Such insights provide constructive information for current or future biological control research efforts. In this study, we investigated a highly variable chloroplast DNA (cpDNA) marker for populations of the weed Lepidium draba (Brassicaceae) in its native Eurasian and in...
متن کاملMolecular data indicate the protostome affinity of brachiopods.
Although the phylogenetic position of brachiopods has always been subject to debate, many authors place them as a sister group to deuterostomes on the basis of morphological and developmental characters. However, molecular phylogeny consistently places them among protostomes. More precisely, brachiopods are predicted to branch inside the lophotrochozoan assemblage, together with annelids, mollu...
