Resolving an Ancient, Rapid Radiation in Saxifragales [PDF]

Systematic Biology, 2008
Despite the prior use of approximately 9000 bp, deep-level relationships within the angiosperm clade, Saxifragales remain enigmatic, due to an ancient, rapid radiation (89.5 to 110 Ma based on the fossil record). To resolve these deep relationships, we constructed several new data sets: (1) 16 genes representing the three genomic compartments within ...

Two new species of Echeveria (Crassulaceae, Saxifragales) from the Sierra de Manantlán, Jalisco, Mexico

Phytotaxa
Two new species are described and illustrated. Echeveria cuevasii shares with E. flammigera typical characteristics of Echeveria of the Nudae series, for instance, a subshruby habit, medium-sized rosettes and short sub spicate inflorescences. However, it differs from the latter by having fewer shorter branches, longer leaves, more flowers per ...

Sequencing Angiosperm Plastid Genomes Made Easy: A Complete Set of Universal Primers and a Case Study on the Phylogeny of Saxifragales [PDF]

Genome Biology and Evolution, 2013
Plastid genomes are an invaluable resource for plant biological studies. However, the number of completely sequenced plant plastid genomes is still small compared with the vast number of species. To provide an alternative generalized approach, we designed a set of 138 pairs of universal primers for amplifying (termed "short-range PCR") and sequencing ...

Floral organ MADS-box genes in Cercidiphyllum japonicum (Cercidiphyllaceae): Implications for systematic evolution and bracts definition. [PDF]

PLoS ONE, 2017
The dioecious relic Cercidiphyllum japonicum is one of two species of the sole genus Cercidiphyllum, with a tight inflorescence lacking an apparent perianth structure.

Hylotelephium spectabile, a New Host for Carnation Tortrix Moth (Cacoecimorpha pronubana) and Molecular Characterization in Greece

Insects, 2021
Cacoecimorpha pronubana (Hübner) (Lepidoptera, Tortricidae) is a highly polyphagous pest of a wide range of crop and ornamental plants. It is of Mediterranean origin and widespread in European and Mediterranean Plant Protection Organization (EPPO) region.

The Conservation of Chloroplast Genome Structure and Improved Resolution of Infrafamilial Relationships of Crassulaceae

Frontiers in Plant Science, 2021
Crassulaceae are the largest family in the angiosperm order Saxifragales. Species of this family are characterized by succulent leaves and a unique photosynthetic pathway known as Crassulacean acid metabolism (CAM).

Degradation of key photosynthetic genes in the critically endangered semi-aquatic flowering plant Saniculiphyllum guangxiense (Saxifragaceae)

BMC Plant Biology, 2020
Background Plastid gene loss and pseudogenization has been widely documented in parasitic and mycoheterotrophic plants, which have relaxed selective constraints on photosynthetic function.

The complete chloroplast genome sequence of Altingia excelsa

Mitochondrial DNA. Part B. Resources, 2020
The first complete chloroplast genome (cpDNA) sequence of Altingia excelsa was determined from Illumina HiSeq pair-end sequencing data in this study. The cpDNA is 160,861 bp in length, contains a large single copy region (LSC) of 89,126 bp and a small ...

W(h)ither Fossils? Studying Morphological Character Evolution in the Age of Molecular Sequences [PDF]

, 2008
A major challenge in the post-genomics era will be to integrate molecular sequence data from extant organisms with morphological data from fossil and extant taxa into a single, coherent picture of phylogenetic relationships; only then will these ...
