Testing the Hypothesis of Multiple Origins of Holoparasitism in Orobanchaceae: Phylogenetic Evidence from the Last Two Unplaced Holoparasitic Genera, Gleadovia and Phacellanthus

open access: yesFrontiers in Plant Science, 2017
Orobanchaceae is the largest family among the parasitic angiosperms. It comprises non-parasites, hemi- and holoparasites, making this family an ideal test case for studying the evolution of parasitism.

The complete plastid genome of Jeffersonia diphylla and its phylogenetic position inference

open access: yesMitochondrial DNA. Part B. Resources, 2020
Jeffersonia diphylla, which belongs to Berberidaceae, is a perennial herb native to North America. In the present study, we determined the first plastome of J. diphylla using genome skimming approach. The pastome of J.

Molecular bases of circadian magnesium rhythms across eukaryotes

open access: yesFEBS Letters, EarlyView.
Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

Phylogenetic Position of African Punctoid Snails (Stylommatophora, Punctoidea, Trachycystinae)

open access: yesTaxonomy, 2022
The punctoid land snail family Charopidae, as currently defined, is a paraphyletic assemblage of taxa with Gondwanan distribution. It is represented in Africa largely by the pinwheels (genus Trachycystis and allies) and afrodontas (genus Afrodonta and ...

Student News [PDF]

open access: yes, 2018
Calyptrates are a megadiverse, actively radiating, group of dipterans, which are widely spread and abundant in nearly all terrestrial environments. Despite huge diversity and economic importance, their phylogeny is far from resolved.

Gut microbiota diversity is prognostic in metastatic hormone receptor‐positive breast cancer patients receiving chemotherapy and immunotherapy

open access: yesMolecular Oncology, EarlyView.
In this exploratory study, we investigated the relationship between the gut microbiota and outcome in patients with metastatic hormone receptor‐positive breast cancer, treated in a randomized clinical trial with chemotherapy alone or chemotherapy in combination with immune checkpoint blockade.

Phylogenetic Analysis of Native Chicken from Bangladesh and Neighboring Asian Countries Based on Complete Sequence of Mitochondrial DNA D-loop Region

open access: yesThe Journal of Poultry Science, 2012
The complete mitochondrial D-loop region was sequenced for a total of 18 individuals of Bangladeshi native chickens (BNC); full feathered (nana) (n=7), naked neck (Nana) (n=8) and Red junglefowl (RJF) (n=3).

Protein O‐glycosylation in the Bacteroidota phylum

open access: yesFEBS Open Bio, EarlyView.
Species of the Bacteroidota phylum exhibit a unique O‐glycosylation system. It modifies noncytoplasmic proteins on a specific amino acid motif with a shared glycan core but a species‐specific outer glycan. A locus of multiple glycosyltransferases responsible for the synthesis of the outer glycan has been identified.
