Megaphylogenetic Specimen-Level Approaches to the Carex (Cyperaceae) Phylogeny Using ITS, ETS, and matK Sequences: Implications for Classification [PDF]

, 2016
We present the first large-scale phylogenetic hypothesis for the genus Carex based on 996 of the 1983 accepted species (50.23%). We used a supermatrix approach using three DNA regions: ETS, ITS and matK.

Evolutionary legacies structure the geography of seagrass traits across the world's oceans

New Phytologist, EarlyView.
Summary Traits modulate species' ability to track shifts in climate, yet the extent to which traits have been shaped by the contemporary environment and/or historical processes remains poorly understood. Here, we fill this gap for the world's seagrasses, habitat‐forming species that provide critical ecosystem services.

A local limit law for the empirical spectral distribution of the anticommutator of independent Wigner matrices [PDF]

, 2013
Our main result is a local limit law for the empirical spectral distribution of the anticommutator of independent Wigner matrices, modeled on the local semicircle law.

Vestigial Plastids in Parasitic Plants: Evolutionary Remnants or Adaptive Innovations?

Plant, Cell &Environment, EarlyView.
ABSTRACT Throughout the evolutionary history of plants, chloroplasts originating from a cyanobacterial endosymbiosis have undergone remarkable adaptation and specialization, giving rise to a multitude of plastid types. The evolution toward parasitism in plants represents a particularly extreme case of such specialization.

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

PLoS 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

Gelechiidae Moths Are Capable of Chemically Dissolving the Pollen of Their Host Plants [PDF]

, 2011
Background: Many insects feed on pollen surface lipids and contents accessible through the germination pores. Pollen walls, however, are not broken down because they consist of sporopollenin and are highly resistant to physical and enzymatic damage. Here

Identification of Crucial Drug Targets and Pathways to Reprogram Drug Resistance Through Epigenetic Modulation in Advanced Lung Cancer Using Integrated Bioinformatics Approach

Computational and Systems Oncology, Volume 6, Issue 1, December 2026.
ABSTRACT Resistance to chemotherapy, which is demonstrated in almost every patient with advanced‐stage lung cancer (ALC), underscores an urgent need to unravel the underlying molecular mechanisms and identify novel strategies to overcome drug resistance. In the present study, an attempt was made to identify epigenetic targets and modulators that can be

Pl\"ucker Embedding of Cyclic Orbit Codes [PDF]

, 2012
Cyclic orbit codes are a family of constant dimension codes used for random network coding. We investigate the Pl\"ucker embedding of these codes and show how to efficiently compute the Grassmann coordinates of the code words.Comment: to appear in ...
