Dolichorhynchus Is United with Douepea (Brassicaceae)

Brassicaceae phylogeny and trichome evolution.

To estimate the evolutionary history of the mustard family (Brassicaceae or Cruciferae), we sampled 113 species, representing 101 of the roughly 350 genera and 17 of the 19 tribes of the family, for the chloroplast gene ndhF. The included accessions increase the number of genera sampled over previous phylogenetic studies by four-fold. Using parsimony, likelihood, and Bayesian methods, we recons...

Health-afecting compounds in Brassicaceae

Comparative genomics of Brassicaceae crops

The family Brassicaceae is one of the major groups of the plant kingdom and comprises diverse species of great economic, agronomic and scientific importance, including the model plant Arabidopsis. The sequencing of the Arabidopsis genome has revolutionized our knowledge in the field of plant biology and provides a foundation in genomics and comparative biology. Genomic resources have been utili...

Is the United Nations catching up with Ebola at last?

Early inMay, six weeks after the first case of Ebola virus disease had been confirmed in west Africa and rapidly spread into three of the poorest countries in the world, the director general of the World Health Organization, Margaret Chan, declared a public health emergency of international concern. It is “an extraordinary event and a public health risk to other states for which a coordinated r...

Toward a global phylogeny of the Brassicaceae.

The Brassicaceae is a large plant family (338 genera and 3,700 species) of major scientific and economic importance. The taxonomy of this group has been plagued by convergent evolution in nearly every morphological feature used to define tribes and genera. Phylogenetic analysis of 746 nrDNA internal transcribed spacer (ITS) sequences, representing 24 of the 25 currently recognized tribes, 146 g...
