Interspecific and intraspecific analysis of Selinum spp. collected from Indian Himalayas using DNA barcoding

Journal of Genetic Engineering and Biotechnology, 2022
Background DNA barcoding is a powerful method for phylogenetic mapping and species identification. However, recent research has come to a consistent conclusion about the universality of DNA barcoding.

Reinstatement of the genus Psorodendron and related systematic novelties as revealed from phylogenetic analyses of the tribe Amorpheae (Leguminosae, Papilionoideae)

Caldasia, 2022
The legume tribe Amorpheae comprises eight genera and ca. 240 species exclusive to the New World. We performed parsimony and maximum likelihood phylogenetic analyses based on sequence data from the nuclear gene CNGC4, the chloroplast trnK/matK genes and ...

Isometry and Automorphisms of Constant Dimension Codes [PDF]

, 2012
We define linear and semilinear isometry for general subspace codes, used for random network coding. Furthermore, some results on isometry classes and automorphism groups of known constant dimension code constructions are ...

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.

Analyzing multi-locus plant barcoding datasets with a composition vector method based on adjustable weighted distance. [PDF]

PLoS ONE, 2012
BackgroundThe composition vector (CV) method has been proved to be a reliable and fast alignment-free method to analyze large COI barcoding data. In this study, we modify this method for analyzing multi-gene datasets for plant DNA barcoding. The modified

Perturbation of transportation polytopes

, 2012
We describe a perturbation method that can be used to reduce the problem of finding the multivariate generating function (MGF) of a non-simple polytope to computing the MGF of simple polytopes.

Complete chloroplast genome sequence of Holoparasite Cistanche Deserticola (Orobanchaceae) reveals gene loss and horizontal gene transfer from Its host Haloxylon Ammodendron (Chenopodiaceae) [PDF]

, 2013
The central function of chloroplasts is to carry out photosynthesis, and its gene content and structure are highly conserved across land plants. Parasitic plants, which have reduced photosynthetic ability, suffer gene losses from the chloroplast (cp ...

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

The In Silico Predicton of the Chloroplast Maturase K Gene Polymorphism in Several Barley Varieties

Agriculture, 2018
This study was conducted to describe the role of the chloroplast maturase K (matK) genetic polymorphism in the reciprocal crossing between five barley varieties using several in vitro / in silico tools.
