The Potassium-Dependent Transcriptome Analysis of Maize Provides Novel Insights into the Rescue Role of Auxin in Responses to Potassium Deficiency

Agronomy, 2022
Potassium (K+) deficiency is a key factor limiting maize growth and yield. Auxin plays an important role in maize adaptation to K+ deficiency, but its physiological and molecular mechanisms are largely unclear. In this study, the exogenous application of

Differential Encoding of Predator Fear in the Ventromedial Hypothalamus and Periaqueductal Grey

Journal of Neuroscience, 2018
The ventromedial hypothalamus is a central node of the mammalian predator defense network. Stimulation of this structure in rodents and primates elicits abrupt defensive responses, including flight, freezing, sympathetic activation, and panic, while ...

Differential consolidation and pattern reverberations within episodic cell assemblies in the mouse hippocampus. [PDF]

PLoS ONE, 2011
One hallmark feature of consolidation of episodic memory is that only a fraction of original information, which is usually in a more abstract form, is selected for long-term memory storage.

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

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...
