What is Conservation Biology?

24.4K
Conservation biology is a scientific field that focuses on the preservation of biodiversity in order to protect ecosystems while meeting the needs of the human population. Humans require properly functioning ecosystems to maintain our supply of natural resources, including food, medicines, and building materials.

Biological Effects of Radiation

18.0K
All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they...

Synthetic Biology

5.6K
Synthetic biology is an interdisciplinary science that involves using principles from disciplines such as engineering, molecular biology, cell biology, and systems biology. It involves remodeling existing organisms from nature or constructing completely new synthetic organisms for applications such as protein or enzyme production, bioremediation, value-added macromolecule production, and the addition of desirable traits to crops, to name a few.

Biological Causes of Schizophrenia01:29

Biological Causes of Schizophrenia

644
Schizophrenia, a severe psychiatric disorder, arises from a complex interplay of biological factors, including genetic predisposition, structural brain abnormalities, neurotransmitter dysregulation, and developmental irregularities. These factors collectively contribute to the onset and progression of the disorder, which typically manifests in late adolescence or early adulthood.
Genetic Factors in Schizophrenia
The genetic basis of schizophrenia is strongly supported by family and twin...

Applications Of NMR In Biology01:25

Applications Of NMR In Biology

4.5K
Nuclear magnetic resonance (NMR) spectroscopy is a very valuable analytical technique for researchers. It has been used for more than 50 years as an analytical tool. F. Bloch and E. Purcell formulated NMR in 1946 and won the 1952 Nobel Prize in Physics  for their work. Biological macromolecules such as proteins, nucleic acids, lipids, and organic molecules including pharmaceutical compounds, can be studied using this versatile tool that exploits the magnetic properties of certain nuclei.

Summary

Strigolactones (SLs) are plant hormones regulating development and stress. This review details designing small molecule probes to understand SL functions in plant biology and chemical ecology.

Area of Science:

  • Plant biology
  • Chemical ecology
  • Hormone signaling

Background:

  • Strigolactones (SLs) are crucial plant hormones involved in development, stress responses, and symbiotic interactions.
  • SLs act as ecological signals, mediating communication between plants and soil microbes (arbuscular-mycorrhizal fungi) and influencing parasitic plant germination.
  • The complex functions of SLs necessitate diverse methodologies for comprehensive study.

Purpose of the Study:

  • To review the design principles of small molecule probes for investigating strigolactone (SL) functions.
  • To highlight how chemical probes aid in understanding SLs' roles in plant architecture, stress responses, and ecological signaling.
  • To provide insights into applying chemical biology approaches to plant hormone research.
