New Insights Into Sunflower (Helianthus annuus L.) FatA and FatB Thioesterases, Their Regulation, Structure and Distribution
(Frontiers Media, 2018)
Sunflower seeds (Helianthus annuus L.) accumulate large quantities of triacylglycerols (TAG) between 12 and 28 days after flowering (DAF). This is the period of maximal acyl-acyl carrier protein (acyl-ACP) thioesterase ...

DNA end resection requires constitutive sumoylation of CtIP by CBX4
(Nature Publishing Group, 2017)
DNA breaks are complex DNA lesions that can be repaired by two alternative mechanisms: non-homologous end-joining and homologous recombination. The decision between them depends on the activation of the DNA resection ...

A genome-wide screening uncovers the role of CCAR2 as an antagonist of DNA end resection
(Nature Publishing Group, 2016)
There are two major and alternative pathways to repair DNA double-strand breaks: non-homologous end-joining and homologous recombination. Here we identify and characterize novel factors involved in choosing between these ...

Social Chemical Communication Determines Recovery From L1 Arrest via DAF-16 Activation
(Frontiers Media, 2020)
In a population, chemical communication determines the response of animals to changing environmental conditions, what leads to an enhanced resistance against stressors. In response to starvation, the nematode Caenorhabditis ...

Protein Activity of the Fusarium fujikuroi Rhodopsins CarO and OpsA and Their Relation to Fungus–Plant Interaction
(MDPI, 2018)
Fungi possess diverse photosensory proteins that allow them to perceive different light wavelengths and to adapt to changing light conditions in their environment. The biological and physiological roles of the green ...

The oxygenase CAO-1 of Neurospora crassa is a resveratrol cleavage enzyme.
(American Society for Microbiology, 2013)
The genome of the ascomycete Neurospora crassa encodes CAO-1 and CAO-2, two members of the carotenoid cleavage oxygenase family that target double bonds in different substrates. Previous studies demonstrated the role of ...

Yeast as a model system to study metabolic impact of selenium compounds
(Shared Science Publishers, 2015)
Inorganic Se forms such as selenate or selenite (the two more abundant forms in nature) can be toxic in Saccharomyces cerevisiae cells, which constitute an adequate model to study such toxicity at the molecular level and ...

Crosstalk between Virulence Loci: Regulation of Salmonella enterica Pathogenicity Island 1 (SPI-1) by Products of the std Fimbrial Operon
(Public Library of Science, 2012)
Invasion of intestinal epithelial cells is a critical step in Salmonella infection and requires the expression of genes located in Salmonella pathogenicity island 1 (SPI-1). A key factor for SPI-1 expression is DNA ...

Host cell type-dependent translocation and PhoP-mediated positive regulation of the effector SseK1 of Salmonella enterica.
(Frontiers Media S. A., 2015)
Salmonella enterica expresses two virulence-related type III secretion systems (T3SSs) encoded in Salmonella pathogenicity island 1 (SPI1) and SPI2, respectively. SseK1 is a poorly characterized substrate of the SPI2-encoded ...

The ribotoxin α-sarcin can cleave the sarcin/ricin loop on late 60S pre-ribosomes
(Oxford University Press, 2020)
The ribotoxin α-sarcin belongs to a family of ribonucleases that cleave the sarcin/ricin loop (SRL), a critical functional rRNA element within the large ribosomal subunit (60S), thereby abolishing translation. Whether ...
