Genetic Dissection of the Regulatory Network Associated with High C-di-GMP Levels in Pseudomonas putida KT2440

Frontiers in Microbiology, 2016
Most bacteria grow in nature forming multicellular structures named biofilms. The bacterial second messenger cyclic diguanosine monophosphate (c-di-GMP) is a key player in the regulation of the transition from planktonic to sessile lifestyles and this ...

Monophonic sets and rough directed topological spaces: Applications with some directed networks

AIMS Mathematics
By using the monophonic paths in the theory of directed graphs, this paper constructs a new topology, called the out mondirected topology, and characterizes the graphs that induce the indiscrete or discrete topology.

Possible Mechanisms for The Effects of Calcium Deficiency on Male Infertility [PDF]

International Journal of Fertility and Sterility, 2019
Calcium (Ca) is a significant element that acts as an intracellular second messenger. It is necessary for many physi- ological processes in spermatozoa including spermatogenesis, sperm motility, capacitation, acrosome reaction and fertilization ...

The second messenger c-di-AMP inhibits the osmolyte uptake system OpuC in Staphylococcus aureus [PDF]

, 2016
Staphylococcus aureus is an important opportunistic human pathogen that is highly resistant to osmotic stresses. In order to survive an increase in osmolarity, bacteria immediately take up potassium and small organic compounds, also referred to as ...

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Root growth and signalling: the role of calcium channels [PDF]

, 2017
Roots acquire calcium not only as a macronutrient but also to serve as a second messenger in signalling and a component of exocytosis for growth. Plasma membrane channels are sufficient to deliver calcium from the apoplast to the cytosol to enable its ...
