Gene Flow

Gene Flow

Gene flow is the transfer of genes among populations, resulting from either the dispersal of gametes or from the migration of individuals.

Background and Environment Affect Phenotype

Background and Environment Affect Phenotype

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...

Viral Mutations

Viral Mutations

A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material...

Mutation, Gene Flow, and Genetic Drift

Mutation, Gene Flow, and Genetic Drift

In a population that is not at Hardy-Weinberg equilibrium, the frequency of alleles changes over time. Therefore, any deviations from the five conditions of Hardy-Weinberg equilibrium can alter the genetic variation of a given population. Conditions that change the genetic variability of a population include mutations, natural selection, non-random mating, gene flow, and genetic drift (small population size).

Area of Science:

Plant Virology
Molecular Evolution
Next-Generation Sequencing

Background:

Plum pox virus (PPV) poses a significant global threat to stone fruit crops.
Woody perennial hosts offer a complex environment for viral evolution across seasons.

Purpose of the Study:

To investigate how seasonal host development influences PPV population structure.
To analyze PPV variants within different host tissues and developmental stages.

Main Methods:

Employed next-generation sequencing of ribosome-associated viral genomes (translatome).
Assessed PPV variants from phloem and whole leaf tissues across various plum developmental stages.

Main Results:

Translatome PPV variants were proportionally higher in developing buds and leaves with low infection levels.
Mature tissues with high infection levels showed proportionally fewer viral variants.
Distinct PPV variant groups were identified based on population frequency and tissue specificity.

Conclusions:

PPV population dynamics are significantly affected by host tissue type.
Seasonal host development plays a crucial role in shaping PPV variant populations.
