Chloroplast phylogenomic analysis provides insights into the evolution of the largest eukaryotic genome holder, Paris japonica (Melanthiaceae)

BMC Plant Biology, 2019
Background Robust phylogenies for species with giant genomes and closely related taxa can build evolutionary frameworks for investigating the origin and evolution of these genomic gigantisms. Paris japonica (Melanthiaceae) has the largest genome that has

Effects of abandonment on plant diversity in seminatural grasslands along soil and climate gradients [PDF]

, 2017
Questions: What are the effects of abandonment on plant diversity in semi-natural grasslands? Do the effects of abandonment on taxonomic and functional diversity vary along environmental gradients of climate and soil?

Stand structural diversity rather than species diversity enhancesaboveground carbon storage in secondary subtropical forests in Eastern China

, 2016
. Stand structural diversity, typically characterized by variances in tree diameter at breast height (DBH) and total height, plays a critical role in influencing aboveground carbon (C) storage.

Making tau amyloid models in vitro: a crucial and underestimated challenge

FEBS Letters, EarlyView.
This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...

Quantification of mesocosm fish and amphibian species diversity via environmental DNA metabarcoding

Molecular Ecology Resources, 2015
Freshwater fauna are particularly sensitive to environmental change and disturbance. Management agencies frequently use fish and amphibian biodiversity as indicators of ecosystem health and a way to prioritize and assess management strategies ...

Unraveling Mycobacterium tuberculosis acid resistance and pH homeostasis mechanisms

FEBS Letters, EarlyView.
Mycobacterium tuberculosis exhibits a remarkable resilience to acid stress. In this Review, we discuss some of the molecular mechanisms and metabolic pathways used by the tubercle bacilli to adapt and resist host‐mediated acid stress. Mycobacterium tuberculosis (Mtb) is a successful pathogen that has developed a variety of strategies to survive and ...

Adelphomyia crane flies (Diptera, Limoniidae) of Korea with identification key for all Palaearctic species [PDF]

ZooKeys
Limnophilinae crane flies belonging to the genus Adelphomyia Bergroth, 1891 of the Korean Peninsula were studied starting from 1937, but only one species A. macrotrichiata (Alexander, 1923) has been recorded from North Korea so far. The genus was unknown

Species scale in diverse dimensions

Journal of High Energy Physics
Abstract In a quantum theory of gravity, the species scale Λ s can be defined as the scale at which corrections to the Einstein action become important or alternatively as codifying the “number of light degrees of freedom”, due to the fact that $$ {\Lambda}_s^{-1} $$

Satellite remote sensing to monitor species diversity: potential and pitfalls

, 2016
Assessing the level of diversity in plant communities from field‐based data is difficult for a number of practical reasons: (1) establishing the number of sampling units to be investigated can be difficult; (2) the choice of sample design can impact on ...

The intracellular domain of TLR2 is capable of high‐affinity Zn binding: possible outcomes for the receptor activation

FEBS Letters, EarlyView.
Toll‐like receptors (TLRs) are important in the innate immune system. This study explores the zinc‐binding ability of the TLR2 TIR domain (TLR2TIR). We found that TLR2TIR binds zinc with nanomolar affinity through its cysteine residues. Two of them, C673 and C713, are vital for receptor activation, indicating that zinc may play a role in initiating ...
