Reduced Responsiveness to Volatile Signals Creates a Modular Reward Provisioning in an Obligate Food-for-Protection Mutualism

Frontiers in Plant Science, 2018
Plants in more than 100 families secrete extrafloral nectar (EFN) to establish food-for-protection mutualisms with ants. Facultative ant-plants secrete EFN as a jasmonic acid (JA)-dependent response to attract generalist ants.

Whole Irradiated Plant Leaves Showed Faster Photosynthetic Induction Than Individually Irradiated Leaves via Improved Stomatal Opening

Frontiers in Plant Science, 2019
Rapid photosynthetic induction is crucial for plants under fluctuating light conditions in a crop canopy as well as in an understory. Most previous studies have focused on photosynthetic induction responses in a single leaf, whereas the systemic ...

A HOSPITAL SIGNAL SYSTEM. [PDF]

JAMA: The Journal of the American Medical Association, 1907
In October, 1904, I devised, for the Hospital of the Good Samaritan, a signal system for calling nurses to patients, which has the following advantages: Noiseless. There being no bells, the call is absolutely silent. Monitor board. This is in the office of the superintendent of nurses and enables this officer or her representatives to observe each ...

Vascular Bundles Mediate Systemic Reactive Oxygen Signaling during Light Stress

, 2020
Systemic signaling and systemic acquired acclimation (SAA) are essential for plant survival during episodes of environmental stress. Recent studies highlighted a key role for reactive oxygen species (ROS) signaling in mediating systemic responses and SAA

Cauliflower mosaic virus, a compatible pathogen of Arabidopsis, engages three distinct defense-signaling pathways and activates rapid systemic generation of reactive oxygen species [PDF]

, 2005
We analyzed expression of marker genes for three defense pathways during infection by Cauliflower mosaic virus ( CaMV), a compatible pathogen of Arabidopsis ( Arabidopsis thaliana), using luciferase reporter transgenes and directly by measuring ...

Systemic movement of FT mRNA and a possible role in floral induction [PDF]

, 2012
FLOWERING LOCUS T (FT) protein is known to be part of the mobile flowering inducing “florigen” signal in plants, but it may not be acting alone. This article reviews the data that FT mRNA can also move systemically throughout the plant and into the shoot

A Role of Myocardin Related Transcription Factor-A (MRTF-A) in Scleroderma Related Fibrosis.

, 2015
In scleroderma (systemic sclerosis, SSc), persistent activation of myofibroblast leads to severe skin and organ fibrosis resistant to therapy. Increased mechanical stiffness in the involved fibrotic tissues is a hallmark clinical feature and a cause of ...

Genetic Interactions Affect Lung Function in Patients with Systemic Sclerosis

G3: Genes, Genomes, Genetics, 2020
Scleroderma, or systemic sclerosis (SSc), is an autoimmune disease characterized by progressive fibrosis of the skin and internal organs. The most common cause of death in people with SSc is lung disease, but the pathogenesis of lung disease in SSc is ...

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Endothelin-1 promotes myofibroblast induction through the ETA receptor via a rac/phosphoinositide 3-kinase/akt-dependent pathway and is essential for the enhanced contractile phenotype of fibrotic fibroblasts

, 2004
The endothelins are a family of endothelium-derived peptides that possess a variety of functions, including vasoconstriction. Endothelin-1 (ET-1) is up-regulated during tissue repair and promotes myofibroblast contraction and migration, hence ...
