The nicotinamide hypothesis revisited—plant defense signaling integrating PARP, nicotinamide, nicotinic acid, epigenetics, and glutathione

FEBS Letters, EarlyView.
Nicotinamide (NIC) and nicotinic acid (NIA) are proposed as stress signaling compounds in plants. Oxidative stress may lead to single strand breaks (SSB) in DNA, which activate poly(ADP‐ribose) polymerase (PARP). NIC and NIA are then formed from NAD. NIC and NIA can promote epigenetic changes leading to the expression of defense genes specific for the ...

Genetic, molecular and expression features of the Pervenets mutant leading to high oleic acid content of seed oil in sunflower

Oléagineux, Corps gras, Lipides, 2002
Pervenets is a sunflower population that displays seed oil with a high oleic acid content [HOAC]. Our aim is to reconcile all the data gathered on this mutant in a unique explanatory mechanism.

FUS mutant human motoneurons display altered transcriptome and microRNA pathways with implications for ALS pathogenesis [PDF]

, 2017
The FUS gene has been linked to amyotrophic lateral sclerosis (ALS). FUS is a ubiquitous RNA-binding protein, and the mechanisms leading to selective motoneuron loss downstream of ALS-linked mutations are largely unknown.

Single cis‐elements in brassinosteroid‐induced upregulated genes are insufficient to recruit both redox states of the BIL1/BZR1 DNA‐binding domain

FEBS Letters, EarlyView.
Phytohormone brassinosteroid‐induced gene regulation by the transcription factor BIL1/BZR1 involves redox‐dependent DNA‐binding alternation and interaction with the transcription factor PIF4. The reduced BIL1/BZR1 dimer binds preferred cis‐elements, while oxidation alters its oligomerization state and disrupts DNA‐binding ability.

Assessment of drought tolerance in Nagina 22 mutants of rice using Poly Ethylene Glycol (PEG)

Electronic Journal of Plant Breeding, 2020
A laboratory experiment was conducted to screen 500 EMS induced mutants of Nagina22 using low molecular osmotic PEG-6000. The analysis of variance showed that all ten characters showed significant variation at 1% probability level.

Return of the malingering mutants [PDF]

British Journal of Cancer, 2013
Of all the hallmark biological features of cancer, drug resistance stands out as the harbinger of bad news for patients and oncologists alike. Cancer cells can employ several adaptive mechanisms for evading chemotherapeutic assault (Redmond et al, 2008) (Table 1). Prominent among these is mutation of the gene(s) encoding the drug targets.

A working model for cytoplasmic assembly of H/ACA snoRNPs

FEBS Letters, EarlyView.
Dyskerin is the component of nuclear H/ACA ribonucleoproteins (RNPs) endowed with pseudouridine synthase catalytic activity. Two isoforms of human dyskerin have been characterized: the abundant Iso1, mainly nuclear, and the shorter Iso3, mainly cytoplasmic but occasionally imported into nuclei.
