Seventy-two potato tubers of 106 tested from plants exposed 1 year in a field were found infected with potato virus S (PVS) in different tests. Ninety-three percent of these were detected by tuber juice inoculation to Nicotiana debneyi Domin. and 90% by serology of 30-cm plants grown from an eye of such tubers. Sap inoculation to N. debneyi of the same young plants proved to be 96% efficient in detecting the virus, and serological tests at bloom stage were the most efficient of all the tests compared.Tests done on all tubers from 18 plants currently infected with PVS showed that 103 of 116 (89%) were infected, and virtually all eyes from 68 infected tubers produced infected plants.Three years of field trials at Fredericton on the spread of PVS showed that the virus moved into virus-free varieties independently of potato virus X (PVX). In 1970, leaf tests showed that virus-free Netted Gems became 12% infected with PVS; in 1971, spread into Green Mountain, Kennebec, and Sebago was 57, 19, and 9%, respectively; and in 1972, 14% spread occurred in Green Mountain and none in Kennebec or Sebago.Greenhouse experiments on transmission of PVS to potato by Myzus persicae (Sulz.) resulted in 3 of 87 (3.4%) plants becoming infected. Other tests with potato virus Y (PVY) to tobacco, Nicotiana tabacum L. var. Samsun, resulted in 83% transmission.

Protein Response

Potato virus X (PVX) belongs to genus Potexvirus. This study characterizes the cellular transcriptome responses to PVX infection in Russet potato at 2 and 3 days post infection (dpi). Among the 1242 differentially expressed genes (DEGs), 268 genes were upregulated, and 37 genes were downregulated at 2 dpi while 677 genes were upregulated, and 265 genes were downregulated at 3 dpi. DEGs related to signal transduction, stress response, and redox processes. Key stress related transcription factors were identified. Twenty-five pathogen resistance gene analogs linked to effector triggered immunity or pathogen-associated molecular pattern (PAMP)-triggered immunity were identified. Comparative analysis with Arabidopsis unfolded protein response (UPR) induced DEGs revealed genes associated with UPR and plasmodesmata transport that are likely needed to establish infection. In conclusion, this study provides an insight on major transcriptional regulatory networked involved in early response to PVX infection and establishment.
