Refining generic limits in Hyacinthinae (Asparagaceae, Scilloideae): Conflict and concordance between morphology and phylogenomics

Journal of Systematics and Evolution, EarlyView.
Using Angiosperms353 and plastid genome skimming approaches, the generic limits of Hyacinthinae were explored using DNA sequences to better understand their evolution. Floral morphology, a traditional generic delimiter, conflicts with the molecular groupings in many cases, but bulb morphology and cytogenetics define similar groups to DNA.

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 ...

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.

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

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.

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.

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
