Summary
Cherry leaf roll virus (CLRV) spread is poorly understood. Our study reveals New Zealand as a likely origin, with Germany playing a key role in its global transmission via fruit trade.
Area of Science:
- Plant pathology
- Virology
- Population genetics
Background:
- Cherry leaf roll virus (CLRV) causes significant damage to fruit crops.
- Understanding CLRV's spatiotemporal spread is crucial for disease management.
- Previous research has advanced CLRV knowledge but not its diffusion patterns.
Purpose of the Study:
- To investigate the spatial diffusion patterns of Cherry leaf roll virus (CLRV).
- To identify the origins and migration pathways of CLRV.
- To inform sustainable management strategies for CLRV.
Main Methods:
- Bayesian phylodynamics framework applied to viral coat protein gene sequences.
- Analysis of 81 CLRV isolates from five countries.
- Phylogenetic and phylogeographic analysis to infer spread.
Main Results:
- Identified New Zealand as a probable origin of CLRV.
- Detected multiple migration routes of CLRV, particularly involving Germany.
- Confirmed the role of cherry trade in CLRV dissemination.
Conclusions:
- Germany is a significant hub for CLRV transmission.
- Phylodynamic analysis provides insights into pathogen spread.
- Findings aid in developing effective CLRV control strategies.

6.1K
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...

Phylogeny is concerned with the evolutionary diversification of organisms or groups of organisms. A group of organisms with a name is called a taxon (singular). Taxa (plural) can span different levels of the evolutionary hierarchy. For instance, the group containing all birds is a taxon (comprising the class Aves), and the group of all species of daisies (the genus Bellis) is a taxon. Phylogenies can likewise include just one genus (i.e., depict species relationships) or span an entire kingdom.

01:09Mutation, Gene Flow, and Genetic Drift
59.3K
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).

Natural selection—probably the most well-known evolutionary mechanism—increases the prevalence of traits that enhance survival and reproduction. However, evolution does not merely propagate favorable traits, nor does it always benefit populations.
