Multi-species Conserved Sequences

4.4K
Next-generation sequencing technologies have created large genomic databases of a variety of animals and plants. Ever since the human genome project was completed, scientists studied the genome of primates, mammals, and other phylogenetically distant living beings. Such large-scale  studies have provided new insights into the evolutionary relationship between organisms.
Although the genome of each species varies greatly from each other, a few sequences are highly conserved. Such conserved...

Hybrid Zones02:29

Hybrid Zones

21.3K
Hybrid zones are narrow regions where two closely related species interact, mate, and produce hybrids. Relative to either parent species, hybrids may possess distinct phenotypic or genetic differences that impact their survival and reproductive success. The genetic variances introduced by hybridization influence species diversity and speciation processes within the hybrid zone.

Area of Science:

  • Materials Science
  • Environmental Science
  • Life Sciences
  • Analytical Chemistry

Background:

  • Synchrotron radiation enables chemical speciation analysis via X-ray absorption spectroscopies (XAS).
  • XAS imaging of large samples uses full-field or raster-scanning, often comparing X-ray fluorescence at diagnostic energies to reduce acquisition time and dose.
  • Multivariate data processing strategies are commonly used for speciation mapping.

Purpose of the Study:

  • To develop a robust framework for high-resolution chemical speciation mapping in large bulk samples.
  • To address theoretical aspects and assumptions in analyzing XAS datasets.
  • To provide practical software implementations for speciation mapping.

Main Methods:

  • Development of a framework for speciation mapping by comparing X-ray fluorescence images at diagnostic energies with known references.
  • Creation of two software implementations: one in the MicroAnalysis Toolkit and a dedicated R script.
  • Application of the procedure to a fossil specimen cross-section.

Main Results:

  • Accurate speciation and concentration mapping achieved.
  • Data collection time reduced by two to three orders of magnitude compared to full spectral acquisition.
  • Total irradiation dose significantly lowered, staying below radiation damage thresholds for sensitive materials.

Conclusions:

  • The developed framework enables efficient and accurate speciation mapping of large, heterogeneous, and radiation-sensitive samples.
  • This approach is particularly suitable for environmental, material, and life sciences.
  • The method substantially decreases experimental time and radiation damage, making it ideal for sensitive sample analysis.
