Published on: December 2, 2016
Summary
Researchers genetically analyzed a slime mold mutation impacting development speed. They identified a recessive mutation on linkage group IV and developed a selection method for similar mutants, finding glucose partially corrects abnormal morphology.
Area of Science:
- * Genetics
- * Developmental Biology
- * Molecular Biology
Background:
- * Slime mold development is a complex process influenced by genetic factors.
- * Understanding mutations affecting developmental speed is crucial for deciphering cellular regulation.
- * Strain FR17 exhibits a mutation impacting the rate of slime mold development.
Purpose of the Study:
- * To genetically analyze a mutation affecting slime mold development speed.
- * To develop a selection procedure for isolating new mutants with similar developmental defects.
- * To investigate the genetic basis of developmental timing in slime molds.
Main Methods:
- * Genetic analysis of slime mold strain FR17.
- * Development of a selection protocol for isolating mutants affecting developmental speed.
- * Complementation tests to assess the genetic relationships between new mutations.
Main Results:
- * A recessive mutation was identified on linkage group IV in strain FR17.
- * A novel selection procedure successfully isolated additional mutants with altered development.
- * Complementation tests were performed on newly isolated mutants.
- * Aberrant morphology in these mutant strains was partially rescued by the addition of glucose during development.
Conclusions:
- * The study successfully identified and characterized a mutation influencing slime mold developmental rate.
- * A new method for isolating developmental mutants was established.
- * Glucose was found to partially alleviate the morphological defects associated with these mutations, suggesting a metabolic or regulatory link.

01:26Phase Contrast and Differential Interference Contrast Microscopy
Phase-Contrast Microscopes
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...

01:18Drugs Affecting GI Tract Motility: Antimicrobials as Antidiarrheal Agents
Acute diarrhea, a common gastrointestinal disturbance, is characterized by the rapid evacuation of fluid stools, leading to an excessive weight in fluid. This condition typically arises from disorders affecting intestinal water and electrolyte transport. It can be triggered by an increased osmotic load within the intestine, excessive secretion of electrolytes and water, mucosal exudation of protein and fluid, or altered intestinal motility. The primary risks of acute diarrhea are dehydration...
01:28Fungal Phylum Microsporidia
Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...
01:27Diversity of Protists IV
Amoebozoa represent a diverse group of terrestrial and aquatic protists that utilize lobe-shaped pseudopodia for locomotion and feeding. This characteristic differentiates them from the Rhizaria, which possess threadlike pseudopodia. The primary classifications within Amoebozoa include gymnamoebas, entamoebas, and the plasmodial and cellular slime molds. Phylogenetic evidence indicates that Amoebozoa diverged from a lineage that ultimately gave rise to fungi and animals.Gymnamoebas and...
01:28Diphtheria
Diphtheria is an acute, toxin-mediated infectious disease that primarily affects the upper respiratory tract. It is caused by Corynebacterium diphtheriae, a Gram-positive, pleomorphic rod that lacks spore-forming capability and exhibits a characteristic club-shaped morphology under microscopic examination. While C. diphtheriae can asymptomatically colonize mucosal surfaces, clinical disease manifests only when the bacterial strain is lysogenized by a specific β-corynephage. This phage...
01:14Atypical Pneumonia
Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease include...
