Mastering DNA Content Estimation by Flow Cytometry as an Efficient Tool for Plant Breeding and Biodiversity Research

open access: yesMethods and Protocols, 2023
Flow cytometry gives a unique opportunity to analyze thousands of individual cells for multiple parameters in a course of minutes. The most commonly used flow cytometry application in plant biology is estimation of nuclear DNA content.

Adaptation to high ethanol reveals complex evolutionary pathways [PDF]

open access: yes, 2015
Tolerance to high levels of ethanol is an ecologically and industrially relevant phenotype of microbes, but the molecular mechanisms underlying this complex trait remain largely unknown.

Heterogeneity Landscape of Circulating Tumor Cells in Clinical Utility

open access: yesAdvanced Therapeutics, EarlyView.
This study reports the heterogeneity spectrum of circulating tumor cells. The factors involved in the spectrum promote CTCs to overcome barriers in the metastatic cascade but impact the clinical outcome of cancer patients. In summary, the heterogeneities in association with CTCs ultimately reduce patient survival and facilitate increasing mortality of ...

Inferring Variation in Copy Number Using High Throughput Sequencing Data in R

open access: yesFrontiers in Genetics, 2018
Inference of copy number variation presents a technical challenge because variant callers typically require the copy number of a genome or genomic region to be known a priori.

Cytogeography of the East Asian Tulips (Amana, Liliaceae)

open access: yesTaxonomy, 2022
Amana Honda (Liliaceae), known as ‘east Asian tulips’, is a spring ephemeral genus endemic to Sino-Japanese Floristic Subregion, mainly distributed in eastern and central China, Japan and the Korean peninsula. Chromosome numbers are reported here for the

PLOIDY AND GENE EXPRESSION IN CLEMENTINE

open access: yesActa Horticulturae, 2015
Polyploidy has long been recognized as an important force in the evolution of flowering plants and often results in novel phenotypes having advantages in adaptation and major interest for agriculture. Many crops, including citrus, are bred to a higher level of ploidy in search of desirable traits.

Genetic Deconvolution of Embryonic and Maternal Cell‐Free DNA in Spent Culture Medium of Human Preimplantation Embryo Through Deep Learning

open access: yesAdvanced Science, EarlyView.
DECENT is a deep learning method that enhances noninvasive preimplantation genetic testing by accurately reconstructing embryonic copy number variations (CNVs) from cell‐free DNA in spent embryo culture media. By mitigating maternal contamination, DECENT improves diagnostic accuracy, even with high contamination levels, offering a reliable, noninvasive

Phylogenetic relationships in Betula (Betulaceae) based on AFLP markers [PDF]

open access: yes, 2008
The genus Betula comprises various species in boreal and temperate climate zones of the Northern Hemisphere. The taxonomy of Betula is controversial and complicated by parallel evolution of morphological traits, polyploidization events, and extensive ...

Choroid Plexus Fibroblast–ILC2 Niche Promotes Adult Hippocampal Neurogenesis after Traumatic Brain Injury

open access: yesAdvanced Science, EarlyView.
This study investigates the role of group 2 innate lymphoid cells (ILC2) in the choroid plexus (ChP) following traumatic brain injury (TBI). ILC2 accumulation alleviates immune infiltration, preserves hippocampal integrity, and improves sensory‐motor and memory functions.

Outstanding intraindividual genetic diversity in fissiparous planarians (Dugesia, Platyhelminthes) with facultative sex.

open access: yes, 2019
Predicted genetic consequences of asexuality include high intraindividual genetic diversity (i.e., the Meselson effect) and accumulation of deleterious mutations (i.e., Muller’s Ratchet), among others.
