First report of Hop stunt viroid in apricot in China.

Abstract

In September 2005, a single symptomatic apricot tree, 'Yin Bai', one of the most popular and widely grown cultivars in China, was discovered in Beijing. Symptoms included a number of yellow spots with an irregular border that scattered in an irregular manner over the leaf surface. Total RNA was extracted and then subjected to PAGE and RT-PCR. Results of both assays were positive for Hop stunt viroid (HSVd). This is thought to be the first report of HSVd isolated from apricot in China.
