Resolving the systematic positions of enigmatic taxa: Manipulating the chloroplast genome data of Saxifragales

open access: closedMolecular Phylogenetics and Evolution, 2018
Accurately resolving the phylogeny of enigmatic taxa is always a challenge in phylogenetic inference. Such uncertainties could be due to systematic errors or model violations. Here, we provide an example demonstrating how these factors affect the positioning of Paeoniaceae within Saxifragales based on chloroplast genome data.

A preliminary assessment of plant–biotic interactions in the Eocene of South China: Evidence from Liquidambar L. (Saxifragales: Altingiaceae)

open access: closedPalaeogeography, Palaeoclimatology, Palaeoecology, 2017
Abstract The study of fossil plant–biotic (mainly arthropod) interactions offers an opportunity to understand the evolutionary process in palaeoecosystems and their response to climate fluctuation. Despite the importance of such investigations, not much is known about plant–arthropod associations from the Cenozoic floras of Asia.

Characterization of the complete chloroplast genome sequence of Bergenia scopulosa (Saxifragales: Saxifragaceae)

open access: closedConservation Genetics Resources, 2017
Bergenia scopulosa (Saxifragaceae) is an endangered perennial herb which is endemic to China. In the present study, the complete chloroplast genome of B. scopulosa was determined by using Illumina pair-end sequencing. The complete chloroplast genome of B. scopulosa was 156,041 bp, consisting of a pair of inverted repeat (IR) regions (25,585 bp each), a

The impact of extinct taxa on understanding the early evolution of Angiosperm clades: an example incorporating fossil reproductive structures of Saxifragales

open access: closedPlant Systematics and Evolution, 2006
A cladistic analysis was performed including five Cretaceous and 31 extant taxa within Saxifragales using a combination of molecular sequence and morphological data in order to elucidate the utility of extinct taxa in illuminating saxifragalean evolution.
