Modern Molecular Taxonomy

52
Advancements in molecular biology have revolutionized the identification and characterization of bacteria, with multiple methods leveraging DNA sequencing for enhanced precision. As sequencing technologies improve and costs decline, these approaches are increasingly used in clinical, environmental, and evolutionary studies.Multilocus Sequence Typing (MLST) examines several housekeeping genes, essential chromosomal genes encoding cellular functions, to distinguish strains. Approximately...

Evolutionary Relationships through Genome Comparisons

5.8K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

Comparing Mitochondrial, Chloroplast, and Prokaryotic Genomes

12.5K
The present-day mitochondrial and chloroplast genomes have retained some of the characteristics of their ancestral prokaryotes and also have acquired new attributes during their evolution within eukaryotic cells. Like prokaryotic genomes, mitochondrial and chloroplast genomes neither bind with histone-like proteins nor show complex packaging into chromosome-like structures, as observed in eukaryotes. Unlike mitotic cell divisions observed in eukaryotic cells, mitochondria and chloroplasts...

Area of Science:

  • Mycology
  • Genomics
  • Pathogen Identification

Background:

  • Mucoralean fungi cause mucormycosis, a severe infection, especially in immunocompromised individuals.
  • Species within Mucorales exhibit significant variation in molecular identification and pathogenicity.
  • Rhizopus, Mucor, and Lichtheimia species are frequently implicated in mucormycosis cases.

Purpose of the Study:

  • To identify target genes for monitoring Mucoralean species.
  • To uncover potential genomic markers of virulence in Mucorales.
  • To conduct a comparative genomic analysis of pathogenic Mucorales.

Main Methods:

  • Whole genome sequencing of 25 Mucorales species and 22 non-Mucorales pathogenic species.
  • Orthogroup extraction using Python scripts to identify Mucorales-specific genes.
  • Orthofinder analysis to assess protein copy numbers and virulence factors.
  • Comparative genomic analysis focusing on frequent pathogens.

Main Results:

  • Mucorales-specific genes were identified across various orthogroups.
  • Genus-specific genes related to cellular structure, metabolism, and signal transduction were annotated.
  • Virulence-associated proteins in Mucorales showed variations in copy numbers.
  • Specific orthologs between Mucorales and non-Mucoralean pathogens were detailed.

Conclusions:

  • Genomic analysis provides insights into Mucoralean pathogenicity and potential diagnostic targets.
  • Identification of specific genes can aid in the molecular monitoring of Mucorales species.
  • Further studies with more samples are recommended to validate potential target genes for mucormycosis.
