Summary
Nuclear calcium signaling is crucial for cellular responses. This review explores how nuclear calcium levels change and their origins, especially during microbial symbioses and stress.
Area of Science:
- Cellular Biology
- Molecular Biology
- Biochemistry
Background:
- Calcium ions (Ca2+) are universal intracellular messengers.
- Nuclear calcium signaling plays a key role in stimulus transduction.
- Understanding nuclear calcium dynamics is vital for cellular function.
Purpose of the Study:
- To review mechanisms controlling nuclear calcium concentration.
- To discuss the origins of nuclear calcium signals.
- To focus on microbial symbioses and abiotic stress contexts.
Main Methods:
- Literature review of recent findings.
- Analysis of experimental data on nuclear calcium.
- Synthesis of information on calcium store dynamics.
Main Results:
- Nuclear calcium concentration is dynamically regulated.
- Specific stimuli trigger changes in nuclear calcium.

01:32The Nucleus
104.8K
The nucleus is a membrane-bound organelle that acts as a control center in a eukaryotic cell. It contains chromosomal DNA, which controls gene expression and precisely regulates the production of proteins within the cell. In contrast, the DNA inside the mitochondria and chloroplast only carries out functions that are specific to those organelles.
Arrangement of DNA within Nucleus
The regulation of gene expression inside the nucleus is dependent on many factors, including the DNA structure. The...

01:25Cell Signaling in Plants
6.3K
Plant cells communicate to coordinate their cycle of growth, flowering and fruiting, and activities in roots, shoots, and leaves in response to the changing environmental conditions. Plant signaling is distinct from animal signaling. Plants primarily utilize enzyme-linked receptors, whereas the largest class of cell-surface receptors in animals are G-protein coupled receptors (GPCRs). Unlike animals, receptor tyrosine kinases are rare in plants. Instead, plants have a diverse class of...

02:03What is Cell Signaling?
131.1K
Despite the protective membrane that separates a cell from the environment, cells need the ability to detect and respond to environmental changes. Additionally, cells often need to communicate with one another. Unicellular and multicellular organisms use a variety of cell signaling mechanisms to communicate to respond to the environment.

02:35Key Elements for Plant Nutrition
24.4K
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

01:45Endocrine Signaling
68.2K
Endocrine cells produce hormones to communicate with remote target cells found in other organs. The hormone reaches these distant areas using the circulatory system. This exposes the whole organism to the hormone but only those cells expressing hormone receptors or target cells are affected. Thus, endocrine signaling induces slow responses from its target cells but these effects also last longer.
