The pear prickle virus (PPV) is believed to have originated in Asia, where it is endemic to various pear species. It is primarily transmitted through aphids and can affect pear trees, leading to symptoms such as leaf curling and fruit distortion. The virus can spread rapidly, particularly in regions where susceptible pear varieties are cultivated. Its discovery and characterization have helped in understanding its impact on pear production and management strategies.
