Morphological plasticity of bacteria-Open questions
Biomicrofluidics
|July 5, 2016
Summary
Bacteria exhibit morphological plasticity, changing shape to adapt to environmental stresses. Advanced microfluidic and nanofabrication technologies offer new ways to study these bacterial shapeshifters and their survival strategies.
Area of Science:
- Microbiology
- Cell Biology
- Biophysics
Background:
- Bacterial morphological plasticity allows adaptation to changing environments.
- The molecular mechanisms driving these adaptive shape changes are largely unknown.
- Environmental factors like stress and nutrient availability induce morphological changes, often linked to cell wall synthesis.
Purpose of the Study:
- To explore the underlying molecular mechanisms of bacterial morphological plasticity.
- To investigate the role of phenotypic heterogeneity in bacterial adaptation.
- To highlight the potential of microfluidic and nanofabrication technologies in studying bacterial morphogenesis.
Main Methods:
- Investigated physical and chemical factors inducing bacterial morphological changes.
- Examined extreme scenarios of morphological plasticity in defective or deficient cell walls.
- Proposed the use of microfluidic and nanofabrication technologies for inducing, isolating, and analyzing morphological variants.
- Suggested employing optimization algorithms for studying morphogenesis network modulation.
Main Results:
- Bacterial morphological plasticity is a survival strategy linked to phenotypic heterogeneity.
- Defective cell walls can induce bacteria to become 'shapeshifters' with diverse morphologies.
- Micro-nanofluidic platforms enable single-cell analysis, including transcriptional and epigenetic profiling.
Conclusions:
- Bacterial morphological plasticity is a crucial adaptive trait for survival under stress.
- Phenotypic heterogeneity contributes to morphological diversity and plasticity.
- Microfluidic and nanofabrication technologies are powerful tools for dissecting the complex mechanisms of bacterial morphogenesis and epigenetic control.

Bacterial and archaeal cells exhibit remarkable diversity in shape and structure, critical in their adaptability and functionality. Among bacteria, the most commonly observed shapes include cocci and bacilli. Cocci are spherical and may exist singly or in groupings such as pairs (diplococci), chains (streptococci), clusters (staphylococci), or tetrads. Bacilli, in contrast, are rod-shaped and can also occur as single cells, in pairs, or chains, depending on their environmental and genetic...

Microorganisms evolve rapidly due to their large population sizes and short generation times, often exhibiting measurable changes within days under laboratory conditions. Natural selection acts on standing genetic variation, enabling the retention and amplification of beneficial traits that confer fitness advantages in changing environments.Adaptive Pigment Regulation in RhodobacterIn Rhodobacter, a genus of purple non-sulfur bacteria, light-harvesting pigments such as bacteriochlorophyll and...

In 1928, bacteriologist Frederick Griffith worked on a vaccine for pneumonia, which is caused by Streptococcus pneumoniae bacteria. Griffith studied two pneumonia strains in mice: one pathogenic and one non-pathogenic. Only the pathogenic strain killed host mice.
Griffith made an unexpected discovery when he killed the pathogenic strain and mixed its remains with the live, non-pathogenic strain. Not only did the mixture kill host mice, but it also contained living pathogenic bacteria that...

Microbial genome evolution is a highly dynamic process shaped by continual gene gain and loss across species and strains. This genomic flexibility allows microorganisms to adapt rapidly to environmental pressures and interactions with other organisms. Central to understanding this diversity is the distinction between the core and pan genomes.The core genome comprises the genes shared by all sampled strains of a species, representing essential functions needed for fundamental cellular processes.

01:26Evolutionary Processes in Microbes
2
Microbial evolution occurs rapidly due to short generation times and a variety of genetic processes, including horizontal gene transfer, mutation, recombination, and genetic drift. These mechanisms collectively enable microbes to adapt swiftly to changing environments.Horizontal gene transfer (HGT) allows genes to move between different species and occurs through three main mechanisms: conjugation, transformation, and transduction. Conjugation involves direct cell-to-cell contact for DNA...

The phylum Tenericutes, which includes the single class Mollicutes, comprises bacteria that lack cell walls. The term "Mollicutes" derives from the Latin word mollis, meaning "soft." These organisms are among the smallest known and are commonly referred to as mycoplasmas due to the prominence of the genus Mycoplasma, which includes well-known human pathogens. Despite their inability to stain gram-positively (a result of their lack of cell walls), mycoplasmas are phylogenetically related to the...
