Phylogenomic insights into the origin of the Norton grape

PLANTS, PEOPLE, PLANET, EarlyView.
Challenges in viticulture such as disease resistance have renewed interest in underutilized cultivars. The Norton grape, one of the earliest popular North American grape cultivars, holds the potential to produce exceptional wine while being resistant to pests and disease. Yet, the ancestry of the Norton grape is controversial.

Chloroplast Genome Yields Unusual Seven-Cluster Structure C [PDF]

arXiv, 2016
We studied the structuredness in a chloroplast genome of Siberian larch. The clusters in 63-dimensional space were identified with elastic map technique, where the objects to be clusterized are the different fragments of the genome. A seven-cluster structure in the distribution of those fragments reported previously has been found.

Comparative analysis of chloroplast and mitochondrial genomes of sweet potato provides evidence of gene transfer

Scientific Reports
The increasing number of plant mitochondrial DNA genomes (mtDNA) sequenced reveals the extent of transfer from both chloroplast DNA genomes (cpDNA) and nuclear DNA genomes (nDNA).

Well-supported phylogenies using largest subsets of core-genes by discrete particle swarm optimization [PDF]

arXiv, 2017
The number of complete chloroplastic genomes increases day after day, making it possible to rethink plants phylogeny at the biomolecular era. Given a set of close plants sharing in the order of one hundred of core chloroplastic genes, this article focuses on how to extract the largest subset of sequences in order to obtain the most supported species ...

The Prostate Microbiome Is Associated With Prostate Size and PSA Level, Independent of Age, in BPH Patients

The Prostate, EarlyView.
ABSTRACT Background The etiology of benign prostatic hyperplasia (BPH) is not well understood, though recent literature suggests that the urinary tract microbiome may play a role. We aimed to examine the prostatic microbiome in BPH and its associations with patient characteristics. Methods Men undergoing Holmium Laser Enucleation of the Prostate (HoLEP)

High Spatio-Temporal-Resolution Detection of Chlorophyll Fluorescence Dynamics from a Single Chloroplast with Confocal Imaging Fluorometer [PDF]

arXiv, 2016
Chlorophyll fluorescence (CF) is a key indicator to study plant physiology or photosynthesis efficiency. Conventionally, CF is characterized by fluorometers, which only allows ensemble measurement through wide-field detection. For imaging fluorometers, the typical spatial and temporal resolutions are on the order of millimeter and second, far from ...

The Pseudoenzyme β‐Amylase9 From Arabidopsis Activates α‐Amylase3: A Possible Mechanism to Promote Stress‐Induced Starch Degradation

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Starch accumulation in plants provides carbon for nighttime use, for regrowth after periods of dormancy, and for times of stress. Both ɑ‐ and β‐amylases (AMYs and BAMs, respectively) catalyze starch hydrolysis, but their functional roles are unclear.

ASAP: Amplification, sequencing & annotation of plastomes

BMC Genomics, 2005
Background Availability of DNA sequence information is vital for pursuing structural, functional and comparative genomics studies in plastids. Traditionally, the first step in mining the valuable information within a chloroplast genome requires ...

Relation between Gene Content and Taxonomy in Chloroplasts [PDF]

arXiv, 2016
The aim of this study is to investigate the relation that can be found between the phylogeny of a large set of complete chloroplast genomes, and the evolution of gene content inside these sequences. Core and pan genomes have been computed on \textit{de novo} annotation of these 845 genomes, the former being used for producing well-supported ...
