Background and Environment Affect Phenotype

6.6K
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Trihybrid Crosses
Some of Mendel’s crosses examined three pairs of contrasting characteristics. Such a cross is called a trihybrid cross. A trihybrid cross is a combination of three individual monohybrid crosses. For example, plant height (tall vs. short), seed shape (round vs. wrinkled), and seed color (yellow vs. green).
The F1 generation plants of a trihybrid cross are heterozygous for all three traits and produce eight gametes. Upon self-fertilization, these gametes have an equal...

Area of Science:

  • Microbial Systematics
  • Genomics
  • Chemotaxonomy

Background:

  • Genomic information integration enhances microbial classification reliability.
  • In silico chemotaxonomic analysis offers faster and more consistent taxonomic reporting.
  • Previous genomic studies rearranged Actinomycetota, but Geodermatophilaceae taxonomy requires further revision.

Purpose of the Study:

  • To re-evaluate the taxonomy of the Geodermatophilaceae family using new genomic data.
  • To characterize four novel strains and establish genotype-phenotype correlations.
  • To propose new genera and reclassify existing species based on phylogenetic and chemotaxonomic analyses.

Main Methods:

  • Phylogenetic analysis of whole proteomes from sequenced type strains.
  • In silico analysis of chemotaxonomic traits.
  • Genotype-phenotype correlation for chemotaxonomy, morphology, and metabolism.
  • Wet-lab validation of in silico chemotaxonomic results.

Main Results:

  • Four novel species within the genus Blastococcus were identified.
  • The genera Blastococcus, Geodermatophilus, and Modestobacter were found to be paraphyletic.
  • Three new genera (Trujillonella, Pleomorpha, Goekera) were proposed, with several species reclassified.
  • In silico chemotaxonomic results generally agreed with wet-lab findings.
  • Genes related to motility, sporulation, and carbon metabolism were identified across the family.

Conclusions:

  • The study proposes a revised taxonomy for Geodermatophilaceae, including new genera and reclassified species.
  • In silico methods show promise for complementing or replacing traditional chemotaxonomic analyses.
  • Genomic insights reveal significant details about the morphology and ecological roles of the family members.
