چکیده

research to have an impact for good. I have spent the last 20 years studying the hormonal regulation of root growth and development, identifying several of the key signals, genes and regulatory networks that control root length, angle and branching in the model plant Arabidopsis. I recently started BBSRC and ERC research fellowships to manipulate water and nutrient uptake efficiency in crops — important traits that are controlled in large part by their root systems’ architecture. My ambition is to exploit the knowledge I have accrued over the last two decades in Arabidopsis, to improve root development in crops.

Morphological diversity in tenrecs (Afrosoricida, Tenrecidae): comparing tenrec skull diversity to their closest relatives

It is important to quantify patterns of morphological diversity to enhance our understanding of variation in ecological and evolutionary traits. Here, we present a quantitative analysis of morphological diversity in a family of small mammals, the tenrecs (Afrosoricida, Tenrecidae). Tenrecs are often cited as an example of an exceptionally morphologically diverse group. However, this assumption ...

Eisenberg, J. F., and Edwin Gould. The Tenrecs: A Study in Mammalian Behavior and Evolution. Smithsonian Contributions to Zoology, 27: 1-137. 1970.—Tenrecs are found only on the island of Madagascar. The biology of the Tenrecidae is described by field and laboratory studies that focused on comparisons of social behavior and communication in several species. Detailed observations on the behavior...

Slow age-dependent decline of doublecortin expression and BrdU labeling in the forebrain from lesser hedgehog tenrecs.

In addition to synaptic remodeling, formation of new neurons is increasingly acknowledged as an important cue for plastic changes in the central nervous system. Whereas all vertebrates retain a moderate neuroproliferative capacity, phylogenetically younger mammals become dramatically impaired in this potential during aging. The present study shows that the lesser hedgehog tenrec, an insectivore...

Asynchronous colonization of Madagascar by the four endemic clades of primates, tenrecs, carnivores, and rodents as inferred from nuclear genes.

Madagascar harbors four large adaptive radiations of endemic terrestrial mammals: lemurs, tenrecs, carnivorans, and rodents. These rank among the most spectacular examples of evolutionary diversification, but their monophyly and origins are debated. The lack of Tertiary fossils from Madagascar leaves molecular studies as most promising to solve these controversies. We provide a simultaneous rec...

The phylogenetic relationships of insectivores with special reference to the lesser hedgehog tenrec as inferred from the complete sequence of their mitochondrial genome.

The complete mitochondrial genome of a lesser hedgehog tenrec Echinops telfairi was determined in this study. It is an endemic African insectivore that is found specifically in Madagascar. The tenrec's back is covered with hedgehog-like spines. Unlike other spiny mammals, such as spiny mice, spiny rats, spiny dormice and porcupines, lesser hedgehog tenrecs look amazingly like true hedgehogs (Er...

Molecular evidence for multiple origins of Insectivora and for a new order of endemic African insectivore mammals.

The traditional views regarding the mammalian order Insectivora are that the group descended from a single common ancestor and that it is comprised of the following families: Soricidae (shrews), Tenrecidae (tenrecs), Solenodontidae (solenodons), Talpidae (moles), Erinaceidae (hedgehogs and gymnures), and Chrysochloridae (golden moles). Here we present a molecular analysis that includes represen...
