A study was made of the effects on respiration by four strains of potato virus X varying in the severity of symptoms they produce on tobacco leaves. No effects on respiration rates were observed in either inoculated or systemically infected but symptomless leaves, even though there was a significant increase in virus concentration during the experimental period. However, a significant increase was detected in any leaves on which symptoms developed, this increase being directly correlated with the severity of symptom expression. At the same time a great increase in virus concentration was found. Measurement of respiration patterns of single local lesions showed that an increase in respiration occurred each time a chlorotic and necrotic ring formed in the tissues. The use of metabolic inhibitors indicated that metabolic controls are different in the leaves infected with latent or mild strains, as compared to those infected with the severe, necrotizing strains.

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.
