Epiphytes, Parasites, and Carnivores

16.6K
Plants often form mutualistic relationships with soil-dwelling fungi or bacteria to enhance their roots’ nutrient uptake ability. Root-colonizing fungi (e.g., mycorrhizae) increase a plant’s root surface area, which promotes nutrient absorption. While root-colonizing, nitrogen-fixing bacteria (e.g., rhizobia) convert atmospheric nitrogen (N2) into ammonia (NH3), making nitrogen available to plants for various biological functions. For example, nitrogen is essential for the...

The Antiviral System of Bacteria and Archaea: CRISPR

CRISPR stands for Clustered Regularly Interspaced Short Palindromic Repeats is a adaptive immune system found in bacteria and archaea that protects against viral infections. This system enables prokaryotic cells to identify, remember, and neutralize foreign genetic elements, primarily bacteriophages, by storing fragments of the invader’s DNA as a genetic memory.The CRISPR immune response begins during an initial infection. Cas (CRISPR-associated) proteins play a central role in this...

Genome editing technologies allow scientists to modify an organism’s DNA via the addition, removal, or rearrangement of genetic material at specific genomic locations. These types of techniques could potentially be used to cure genetic disorders such as hemophilia and sickle cell anemia. One popular and widely used DNA-editing research tool that could lead to safe and effective cures for genetic disorders is the CRISPR-Cas9 system. CRISPR-Cas9 stands for Clustered Regularly Interspaced...

Bacteria and archaea are susceptible to viral infections just like eukaryotes; therefore, they have developed a unique adaptive immune system to protect themselves. Clustered regularly interspaced short palindromic repeats and CRISPR-associated proteins (CRISPR-Cas) are present in more than 45% of known bacteria and 90% of known archaea.
The CRISPR-Cas system stores a copy of foreign DNA in the host genome and uses it to identify the foreign DNA upon reinfection. CRISPR-Cas has three different...

Heat Engines

3.6K
A heat engine is a device used to extract heat from a source and then convert it into mechanical work used for various applications. For example, a steam engine on an old-style train can produce the work needed for driving the train.
Whenever we consider heat engines (and associated devices such as refrigerators and heat pumps), we do not use the standard sign convention for heat and work. For convenience, we assume that the symbols Qh, Qc, and W represent only the amounts of heat transferred...

Area of Science:

  • Parasitology
  • Glycobiology
  • Molecular Biology

Background:

  • Toxoplasma gondii is a widespread intracellular parasite affecting humans.
  • The parasite's genome contains enzymes crucial for glycan (carbohydrate) synthesis and metabolism.
  • Understanding these pathways is key to addressing infection and immune responses.

Purpose of the Study:

  • To develop and characterize CRISPR/Cas9-based gene knockouts targeting glyco-relevant genes in T. gondii.
  • To create a valuable resource for studying the parasite's carbohydrate biology.
  • To investigate the role of parasite glycans in infection and host immunomodulation.

Main Methods:

  • Utilized CRISPR/Cas9 gene-editing technology to generate targeted gene knockouts.
  • Performed glycomic analyses to assess changes in carbohydrate profiles.
  • Conducted functional assays to evaluate the impact of gene knockouts on parasite biology.

Main Results:

  • Successfully created a library of glyco-relevant gene knockouts in T. gondii.
  • Characterized the glycomic and functional consequences of these genetic modifications.
  • Established a new research tool for exploring T. gondii's unique carbohydrate-related pathways.

Conclusions:

  • The generated gene knockout library is a significant resource for the T. gondii research community.
  • This work provides insights into the function of specific glycan-modifying enzymes.
  • Further studies using this resource will enhance understanding of carbohydrate roles in T. gondii infection and host immune evasion.
