This mechanism was recently described for the first time by a team of scientists from CNRS and Universite de Toulouse III – Paul Sabatier. This discovery opens the door to developing new, more effective antibiotic treatments that target this bacterial communication system.

Discovery of A New Defense Mechanism in Bacteria:

Upon detecting a stress factor, bacteria rapidly induce changes in gene expression and physiological properties to become less vulnerable to the harmful substance. They also produce small ‘alarmone’ proteins on their surface to contact and activate neighboring bacteria.

Unstressed bacteria can only change their state when exposed to a sufficient amount of alarmones, meaning that a stressor must affect a significant number of bacteria to trigger the propagation of this activation.

Structure of Alarmone

Alarmone is primarily composed of guanosine tetraphosphate (ppGpp) and guanosine pentaphosphate (pppGpp). These molecules are derivatives of guanosine triphosphate (GTP), modified by the addition of extra phosphate groups. The core structure consists of a guanine base linked to a ribose sugar, which is further connected to a chain of phosphate groups.

The synthesis of Alarmone

It is mediated by specific enzymes, namely RelA and SpoT. RelA primarily synthesizes ppGpp and pppGpp in response to amino acid starvation, while SpoT can both synthesize and degrade these molecules in response to a variety of stress signals. This dual functionality of SpoT allows bacteria to finely tune their stress response.

Function of Alarmone

The primary role of alarmone is to mediate the bacterial response to environmental stress. They achieve this by altering the expression of numerous genes and modulating various cellular processes. Here are the key functions of alarmone in bacteria:

1. Regulation of Gene Expression: Alarmones bind to RNA polymerase and other regulatory proteins, causing changes in gene expression. This results in the downregulation of genes involved in growth and division and the upregulation of genes associated with stress response and survival.
2. Metabolic Adjustment: By influencing the expression of genes involved in metabolism, alarmones enable bacteria to adapt their metabolic activities to the prevailing environmental conditions. This often involves a reduction in anabolic processes and an increase in catabolic processes, optimizing energy use and resource allocation.
3. Inhibition of DNA Replication and Protein Synthesis: Alarmones play a critical role in halting DNA replication and protein synthesis during stress. This helps prevent the accumulation of damaged proteins and DNA, which could be detrimental to the cell. Instead, the cell focuses on repair and maintenance activities.
4. Coordination with Other Stress Responses: Alarmones interact with other regulatory networks, such as toxin-antitoxin systems, efflux pumps, and biofilm formation pathways. This coordination ensures a comprehensive and effective response to stress, enhancing the bacteria’s ability to withstand and recover from hostile conditions.
5. Promotion of Survival Strategies: The production of alarmones can trigger various survival strategies, including sporulation in certain bacteria, which allows them to endure extreme conditions until the environment becomes favorable again.

Frequently Asked Question(FAQ):

Some curious fragments of DNA hidden within genomes across all life forms have historically been overlooked, as they appeared to have no role in survival competition—until now. Phage viruses, that used regularly to combat against antibiotic resistance, gain an advantage with the help of these curious fragments or selfish genetic elements of viruses by inhibiting a competitor’s ability to reproduce.

Discovery of Selfish Genetic Elements of Viruses

• Decades ago, biologists noted the existence of selfish genetic elements but could not identify any role they played in aiding the host organism’s survival and reproduction.
• Research by scientists at the University of California San Diego has uncovered new evidence suggesting that these DNA elements might not be so selfish after all. Instead, they seem to play a significant role in the interactions between competing organisms.
• In this new study, which focused on “jumbo” phages, the researchers examined the dynamics when two phages co-infect a single bacterial cell and compete with each other.
• They closely studied endonuclease, an enzyme that acts as a DNA-cutting tool. The endonuclease from one phage’s mobile intron interferes with the genome of the competing phage.
• This enzyme cuts an essential gene in the competitor’s genome, sabotaging its ability to properly assemble its progeny and reproduce.
• This weaponized intron endonuclease gives a competitive advantage to the phage carrying it.
• “We were able to clearly delineate the mechanism that gives an advantage and how that happens at the molecular level,” said Chase Morgan, a co-first author of the paper.

Why Viruses are Not So selfish After All

• The DNA segments, known as selfish genetic elements of viruses or bacteriophages (phages) were believed to exist solely to reproduce and spread themselves, offering no apparent benefit to their host organisms.
• Scientists saw them as genetic hitchhikers, inconsequentially passed down through generations.
• The selfish genetic elements known as “mobile introns” give their virus hosts a competitive edge against other viruses: phages have weaponized mobile introns to disrupt the reproduction of competing phages.

Significance of This Discovery

• The selfish genetic elements are not always purely ‘selfish’ has broad implications for understanding genome evolution across all kingdoms of life.”
• The study’s results are crucial as phage viruses are increasingly used as therapeutic tools against antibiotic-resistant bacteria.
• Doctors have been using “cocktails” of phages to combat infections in this growing crisis, and the new information will likely be significant when multiple phages are deployed.
• Understanding that some phages use selfish genetic elements as weapons against others could help researchers understand why certain phage combinations may not achieve their full therapeutic potential.
• “The phages in this study can be used to treat patients with bacterial infections associated with cystic fibrosis,” said Biological Sciences Professor Joe Pogliano.

Role of RNA in Gene Expression:

• RNA (ribonucleic acid) is essential for converting DNA information into proteins. There are various types of RNA, including messenger RNA (mRNA).
• Just visit types of RNA here
• As a type of coding RNA, mRNA’s function is to carry the genetic instructions for protein synthesis from the DNA in the cell nucleus to the cytoplasm, where these instructions are used by other cellular components to produce proteins.
• In addition to coding RNA, cells produce large quantities of non-coding RNA. A significant portion of this non-coding RNA is complementary to mRNA and is known as antisense RNA (asRNA). The role of asRNA has long been a mystery.

How Cells Enhance Gene Expression:

• The research team team discovered that antisense RNA binds with mRNA, facilitating its transport from the cell nucleus to the cytoplasm.
• This results in faster translation of mRNA into proteins compared to when antisense RNA is absent.
• Thus, antisense RNA acts as a “booster” for gene expression, which is crucial for cells, especially when facing harmful environmental conditions or stress.

Prospect of This Research:

• This new research builds on the team’s previous work, also published in Nature, which demonstrated that mRNAs activated under stress bypass quality control.
• The recent findings clarify why cells produce large amounts of antisense RNA (asRNA), given the significant energy investment involved.
• The newly identified mechanism explains how cells rapidly respond to external stimuli by producing essential proteins in large quantities, allowing them to adapt to environmental changes or enter specific developmental stages.
• This new understanding positions asRNAs at the forefront of research into disease development and potential treatments.

To explain how cells enhance gene expression Professor Heike Krebber from Gottingen University’s Institute of Microbiology and Genetics said “I couldn’t believe that cells would generate RNAs without a purpose. This goes against natural principles.”
