Figures and Tables from this paper

Phylogeny and systematics of the tribe Thlaspideae (Brassicaceae) and the recognition of two new genera
TLDR
Thlaspideae is an Old World tribe of Brassicaceae centered in SW Asia that was analyzed using nuclear ITS and chloroplast trnL-F markers in a family-wide context and corroborated Thlaspidae as a well-supported monophyletic clade.
Pleistocene radiation of the serpentine-adapted genus Hesperolinon and other divergence times in Linaceae (Malpighiales).
TLDR
Hesperolinon is an excellent example of edaphic neoendemism, in support of Raven and Axelrod's hypothesis for the genus, and the diversification of Linaceae is more recent than previously estimated.
Morphological and genetic discrepancies in populations of Oreocarya paradoxa and O. revealii: the impact of edaphic selection on recent diversification in the Colorado Plateau.
TLDR
Soil chemistry failed to explain genetic or morphological identity in either Oreocarya revealii or O. paradoxa, and a discontinuity was identified between the morphological and genetic identity in several populations, suggesting incomplete lineage sorting and the nonfixation of identifying morphological traits.
Development of 15 microsatellite loci in the endangered Streptanthus glandulosus subsp. niger (Brassicaceae)
TLDR
These are the first microsatellites reported for this subspecies, and they will aid in the inclusion of genetic information in conservation planning, and were demonstrated in two related taxa, including one of conservation concern.
Two cryptic species of California mustard within Caulanthus lasiophyllus
TLDR
Two cryptic species within C. lasiophyllus are distinguished at the molecular, geographic, and climatic scales, but an ephemeral basal leaf character may help distinguish the species.
Evolution of selenium hyperaccumulation in Stanleya (Brassicaceae) as inferred from phylogeny, physiology and X-ray microprobe analysis.
TLDR
It is suggested that Se tolerance and the capacity to produce organic Se are likely prerequisites for Se hyperaccumulation in Stanleya.
Transcriptome Signatures of Selection, Drift, Introgression, and Gene Duplication in the Evolution of an Extremophile Endemic Plant
TLDR
Analysis of paralogs within each taxon revealed the signature of a period of elevated gene duplication that is shared with other species of the tribe Thelypodieae, and may have played a role in the striking morphological and ecological diversity of this tribe.
Flowering time evolution is independent of serpentine tolerance in the California flora
TLDR
The long-term evolutionary responses of flowering time in a lineage that becomes tolerant of serpentine are variable across genera, with no significant overall bias toward earlier or later flowering.
TWO NEW SPECIES OF STREPTANTHUS (BRASSICACEAE) IN SOUTHERN CALIFORNIA, AND NOTES ON THEIR CONSERVATION
TLDR
Two new species are described based on phylogenetic, morphological, geographical, and ecological evidence, and diagnoses are provided, a table comparing morphological characters, a taxonomic key, and maps showing their geographic ranges are provided.
Sporadic genetic connectivity among small insular populations of the rare geoendemic plant Caulanthus amplexicaulis var. barbarae (Santa Barbara Jewelflower).
TLDR
Data showed that a substantial component of genetic connectivity of this taxon is not at equilibrium, and instead showed sporadic gene flow, which could provide a foundation upon which to model its future evolutionary potential and long-term viability in a changing environment.

Evolution of Caulanthus amplexicaulis var. barbarae (Brassicaceae), a rare serpentine endemic plant: a molecular phylogenetic perspective.
TLDR
Evidence is presented that supports a "biotype depletion" model for the origin of this rare endemic taxon C. amplexicaulis var.
Systematics and phylogeny of the Brassicaceae (Cruciferae): an overview
A critical review of characters used in the systematics of the Brassicaceae is given, and aspects of the origin, classification, and generic delimitation of the family discussed. Molecular
Phylogenetic relationships in the tribes Schizopetaleae and Thelypodieae (Brassicaceae) based on nuclear ribosomal ITS region and plastid ndhF DNA sequences.
TLDR
Maximum parsimony, Bayesian, and maximum-likelihood analyses all support the separate recognition of three distinct and generally well-supported clades within the New World tribe Schizopetaleae.
Phylogeny of Sisymbrium (Brassicaceae) based on ITS sequences of nuclear ribosomal DNA
TLDR
Using sequence data from the internal transcribed spacers of nuclear ribosomal DNA and the 5.8S rRNA gene, this work examined the evolutionary relationships of Old and New World Sisymbrium species with its segregate genera and the validity of O.E. Schulz's classical sectional treatment of SisyMBrium.
The evolution of the Streptanthus glandulosus complex (Cruciferae): genetic divergence and gene flow in serpentine endemics
TLDR
An analysis of the levels and distribution of allozyme variation in the Streptanthus glandulosus species complex was undertaken to test paradigms of speciation processes in the context of serpentine endemism, consistent with a hypothesis of a paleoendemic origin of the complex.
Brassicaceae phylogeny inferred from phytochrome A and ndhF sequence data: tribes and trichomes revisited.
TLDR
It is indicated that dendritic, medifixed, and stellate trichomes likely evolved independently several times in the Brassicaceae, and the evolution of different trichome morphologies using the AU test.
Closing the gaps: phylogenetic relationships in the Brassicaceae based on DNA sequence data of nuclear ribosomal ITS region
TLDR
The results fully support the recent findings that the tribes Schizopetaleae and Thelypodieae ought to be recognized as two distinct tribes instead of a single tribe, as well as provide some support for the re-establishment of the tribe Cremolobeae.
Combining Data from DNA Sequences and Morphology for a Phylogeny of Moringaceae (Brassicales)
TLDR
Parsimony analyses of morphological data and DNA sequences from a low-copy nuclear region, a chloroplast region, and a tandemly-repeated nuclear region present in high copy number (ITS) found relationships within Moringa to be largely congruent with a previous study of wood anatomy.
VARIATION IN FERTILITY OF HYBRIDS BETWEEN ISOLATED POPULATIONS OF THE SERPENTINE SPECIES, STREPTANTHUS GLANDULOSUS HOOK
TLDR
Results are presented of fornian serpentine soils, and other ashybridizations involving thirty-two differpeets of this striking form of endemism ent population samples of Streptanthus glandulosus that have been applied to a taxonomic interpreta.
A comparative genomic map for Caulanthus amplexicaulis and related species (Brassicaceae)
TLDR
Both the patterns of marker segregation and the comparative map indicate that C. amplexicaulis is a diploid organism with a compact genome, and it is demonstrated that the genomic tools developed here will be portable throughout the Streptanthoid Complex.
