Symbiotic diversity, specificity and distribution of rhizobia in native legumes of the Core Cape Subregion (South Africa).
Rhizobial diversity and host preferences were assessed in 65 native Fynbos legumes of the papilionoid legume tribes Astragaleae, Crotalarieae, Genisteae, Indigofereae, Millettieae, Phaseoleae,Expand

Rapid radiation of Impatiens (Balsaminaceae) during Pliocene and Pleistocene: result of a global climate change.
Impatiens comprises more than 1000 species and is one of the largest genera of flowering plants. The genus has a subcosmopolitan distribution, yet most of its evolutionary history is unknown.Expand

Diversification of myco-heterotrophic angiosperms: Evidence from Burmanniaceae
BackgroundMyco-heterotrophy evolved independently several times during angiosperm evolution. Although many species of myco-heterotrophic plants are highly endemic and long-distance dispersal seemsExpand

Phylogenetic utility of the AP3/DEF K-domain and its molecular evolution in Impatiens (Balsaminaceae).
APETALA3 (AP3)/DEFICIENS (DEF) is a MADS-box transcription factor that is involved in establishing the identity of petal and stamen floral organs. The AP3/DEF gene lineage has been extensivelyExpand

New insights in the long-debated evolutionary history of Triuridaceae (Pandanales).
The mycoheterotrophic plant family Triuridaceae (Pandanales) is hypothesized to be an old family, mainly based on its pantropical distribution. The existence of fossils from the Upper Cretaceous,Expand

Recombination and horizontal transfer of nodulation and ACC deaminase (acdS) genes within Alpha- and Betaproteobacteria nodulating legumes of the Cape Fynbos biome.
The goal of this work is to study the evolution and the degree of horizontal gene transfer (HGT) within rhizobial genera of both Alphaproteobacteria (Mesorhizobium, Rhizobium) and BetaproteobacteriaExpand

Long-term warming alters richness and composition of taxonomic and functional groups of arctic fungi.
Fungi, including symbionts, pathogens and decomposers, play crucial roles in community dynamics and nutrient cycling in terrestrial ecosystems. Despite their ecological importance, the response ofExpand

Floral development in three species of Impatiens (Balsaminaceae)
The floral morphological and developmental patterns in three species of Impatiens (Balsaminaceae), namely I. columbaria, I. hawkeri, and I. niamniamensis, were studied to contribute to a betterExpand

Scalariform-to-simple transition in vessel perforation plates triggered by differences in climate during the evolution of Adoxaceae
Background and Aims Angiosperms with simple vessel perforations have evolved many times independently of species having scalariform perforations, but detailed studies to understand why theseExpand

Evolutionary history of the Afro-Madagascan Ixora species (Rubiaceae): species diversification and distribution of key morphological traits inferred from dated molecular phylogenetic trees.
BACKGROUND AND AIMS Previous work on the pantropical genus Ixora has revealed an Afro-Madagascan clade, but as yet no study has focused in detail on the evolutionary history and morphological trendsExpand
