RbCl Uber-Competent Cells v1 [PDF]

, 2019
A protocol kindly provided to our team by the advisor to the 2018 MIT iGEM team (Dr. Brian Teague). It is modified slightly from that version (made by Stefan Maas in 1997) to fit our needs. Stefan Maas' protocol is similar to the Hanahan, D. protocol from 1983. It worked pretty well to make good competent cells in Summer 2018 and we just used it again

Hidden lineages in the African Sky Islands: A taxonomic reevaluation of Afrocarduus (Compositae)

Journal of Systematics and Evolution, EarlyView.
Species delimitation is crucial for biodiversity studies. Using Hyb‐Seq and phylogenomics, we reassessed Afrocarduus, endemic to Afromontane and Afroalpine regions, uncovering 16 evolutionary lineages (2.3 Mya). Morphological data support their distinctiveness, with acaulescence evolving independently twice. The traditionally broad A.

Molecular phylogenetics of Melastomataceae and Memecylaceae [PDF]

, 2001
Melastomataceae are among the most abundant and diversified groups of plants throughout the tropics, but their intrafamily relationships and morphological evolution are poorly understood. Here we report the results of parsimony and maximum likelihood (ML)

Integrative phylogenomics and morphology reveal the evolution and biogeography of Encephalartos (Zamiaceae)

Journal of Systematics and Evolution, EarlyView.
We aimed to conduct phylogenetic analyses of Encephalartos, a cycad genus endemic to Africa, using 3545 single‐copy nuclear genes extracted from transcriptome data, covering 64/65 of the recognized species, along with inference of divergence times using two secondary calibration points.

Integrative taxonomy supports DNA barcoding in revealing an abundant cryptic species in the United States Coastal Plain

Journal of Systematics and Evolution, EarlyView.
We present the most densely sampled phylogeny of Carex section Lupulinae to date (107 specimens) and describe herein a new cryptic species for science from the southern United States, which is locally abundant and found in well‐explored and densely populated areas. Combining DNA sequences with morphometric data obtained from 299 samples, we Demonstrate
