Genome wide association studies for acid phosphatase activity at varying phosphorous levels in Brassica juncea L

open access: yesFrontiers in Plant Science, 2022
Acid phosphatases (Apases) are an important group of enzymes that hydrolyze soil and plant phosphoesters and anhydrides to release Pi (inorganic phosphate) for plant acquisition. Their activity is strongly correlated to the phosphorus use efficiency (PUE)

A PNPase dependent CRISPR System in Listeria. [PDF]

open access: yesPLoS Genetics, 2014
The human bacterial pathogen Listeria monocytogenes is emerging as a model organism to study RNA-mediated regulation in pathogenic bacteria. A class of non-coding RNAs called CRISPRs (clustered regularly interspaced short palindromic repeats) has been ...

Analysis of mRNA Decay Intermediates in Bacillus subtilis 3′ Exoribonuclease and RNA Helicase Mutant Strains

open access: yesmBio, 2022
The Bacillus subtilis genome encodes four 3′ exoribonucleases: polynucleotide phosphorylase (PNPase), RNase R, RNase PH, and YhaM. Previous work showed that PNPase, encoded by the pnpA gene, is the major 3′ exonuclease involved in mRNA turnover; in a ...

The ribonuclease PNPase is a key regulator of biofilm formation in Listeria monocytogenes and affects invasion of host cells

open access: yesnpj Biofilms and Microbiomes, 2023
Biofilms provide an environment that protects microorganisms from external stresses such as nutrient deprivation, antibiotic treatments, and immune defences, thereby creating favorable conditions for bacterial survival and pathogenesis. Here we show that

On the Lubensky-Nelson model of polymer translocation through nanopores [PDF]

open access: yesBiophys. J. 103, 889 (2012), 2012
We revisit the one-dimensional stochastic model of Lubensky and Nelson [Biophys. J 77, 1824 (1999)] for the electrically driven translocation of polynucleotides through alpha-hemolysin pores. We show that the model correctly describes two further important properties of the experimentally observed translocation time distributions, namely their spread ...

Identification of Polynucleotide Phosphorylase (PNPase) in Escherichia coli Involved in Persister Formation

open access: yesbioRxiv, 2018
Despite the identification of many genes and pathways involved in the persistence phenomenon of bacteria, the mechanisms of persistence are not well understood.

Bloch oscillations of a soliton in a molecular chain [PDF]

open access: yesThe European Physical Journal B, 55, 85-87 (2007), 2013
The paper presents results of numerical experiments simulating Bloch oscillations of solitons in a deformable molecular chain in a constant electric field. By the example of a homogeneous polynucleotide chain it is shown that the system under consideration can demonstrate complicated dynamical regimes when at the field intensities less than a certain ...

Cardiovascular Disease Management and Prevention in Saudi Arabia: Strategies, Risk Factors, and Targeted Interventions

open access: yesInternational Journal of Clinical Practice, Volume 2025, Issue 1, 2025.
Cardiovascular diseases (CVDs) remain the main cause of mortality and are generally among the leading causes of morbidity worldwide, thus placing an immense burden on health care. They include coronary artery disease, heart failure, hypertensive heart disease, and stroke. Among these, common risk factors include hypertension, high cholesterol, diabetes,

Defects of mitochondrial RNA turnover lead to the accumulation of double-stranded RNA in vivo.

open access: yesPLoS Genetics, 2019
The RNA helicase SUV3 and the polynucleotide phosphorylase PNPase are involved in the degradation of mitochondrial mRNAs but their roles in vivo are not fully understood.

Novel resources to investigate leaf plasmodesmata formation in C3 and C4 monocots

open access: yesThe Plant Journal, Volume 120, Issue 5, Page 2207-2225, December 2024.
SUMMARY Plasmodesmata (PD) are nanochannels that facilitate cell‐to‐cell transport in plants. More productive and photosynthetically efficient C4 plants form more PD at the mesophyll (M)‐bundle sheath (BS) interface in their leaves than their less efficient C3 relatives.
