Taxonomic assessment of Allium species from Kazakhstan based on ITS and matK markers

open access: yesBMC Plant Biology, 2017
As part of nation-wide project to infer the genetic variation of the native flora in Kazakhstan, a study was attempted to assess phylogenetic relationships of endemic and rare Allium species.

Petrocodon gracilis (Gesneriaceae) is a synonym of P. mirus based on morphological and molecular data

open access: yesNordic Journal of Botany, EarlyView.
Petrocodon gracilis T.Ding & B.Pan and P. mirus X.Z.Shi, J.X.Fu & Li H.Yang are two recently described species exhibiting nearly identical morphology. To determine whether they represent the same taxon, we compared their type localities, type materials, and morphological features and conducted phylogenetic analyses using the nuclear internal ...

Perturbation of transportation polytopes

open access: yes, 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.

Secrets within stems: The cryptic Apodanthes caseariae (Apodanthaceae), a rare neotropical holoendoparasite

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Holoendoparasites are extremely rare plants that live entirely hidden inside their hosts, with only flowers and fruits visible. We studied Apodanthes caseariae, found in central and South America, parasitizing Casearia sylvestris. Little is known about its life cycle.

Identification and Genetic Diversity Analysis of Cinnamomum parthenoxylon (Jack) Meisn Species in Song Hinh Protection Forest, Vietnam Based on Three Chloroplast Gene Regions

open access: yesBiomedical and Biotechnology Research Journal
Background: Cinnamomum parthenoxylon is an important component of tropical Vietnam and has major ecological and economic significance, which has been threatened in recent decades due to the destruction of its habitat and overexploitation. Methods: In the

rbcL and matK earn two thumbs up as the core DNA barcode for ferns.

open access: yesPLoS ONE, 2011
BackgroundDNA barcoding will revolutionize our understanding of fern ecology, most especially because the accurate identification of the independent but cryptic gametophyte phase of the fern's life history--an endeavor previously impossible--will finally

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

open access: yes, 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 ...

Phylogeny and historical biogeography of the Pachira sensu lato clade (Bombacoideae, Malvaceae) with a new infrageneric classification

open access: yesTAXON, EarlyView.
Abstract We explore phylogenetic relationships within the Pachira sensu lato clade (Bombacoideae, Malvaceae), test the monophyly of the genera Eriotheca and Pachira, and investigate their biogeographic history. The Pachira s.l. clade comprises ca. 72 species that traditionally have been placed in Eriotheca and Pachira. We sampled ca. 79% of its species

Identification of the nonreceptor tyrosine kinase MATK/CHK as an essential regulator of immune cells using Matk/CHK-deficient mice

open access: yesBlood, 2006
AbstractMatk/CHK knockout mice were reported to show no apparent phenotypic abnormalities. This was thought to be due to the homologous kinase Csk that compensates for Matk/CHK. Here, we present the first evidence that the nonreceptor tyrosine kinase, Matk/CHK, is an important modulator of immune cell signaling. We found that the frequency of primitive
