One virulent and three avirulent potato virus X strains were characterized qualitatively and quantitatively by the reactions of Gomphrena globosa and Capsicum frutescens. Spontaneous virulent mutants arose from time to time in the avirulent strains cultured in Datura stramonium. Avirulent strains developing low virus concentrations in their host plant had higher mutation rates than one developing a higher concentration in the host.

Este trabalho foi realizado com onze isolados do Potato Vírus X (PVX), sendo seis do Centro de Indexação de Vírus Minas Gerais (VIC, LAV, UF, NR, SJ, UDI), um de São Paulo (VEL), dois do Rio Grande do Sul (P21 e P22), um de Santa Catarina (CAN) e um do Distrito Federal (BR). Os isolados de PVX foram inoculados mecanicamente, em duas épocas diferentes (setembro de 2001 e julho de 2002), em hospedeiras diversas, para verificação da sua agressividade e sintomatologia induzida nos hospedeiros, com a finalidade de se fazer sua diferenciação. A diagnose foi feita por inspeção visual e DAS-ELISA. Foram feitas também tentativas de recuperação dos vírus em plantas com DAS-ELISA negativo, por inoculação nas plantas indicadoras Gomphrena globosa e Nicotiana tabacum 'TNN'. Os sintomas induzidos pelos isolados de PVX na maioria das plantas foram semelhantes, com exceção de Nicotiana glutinosa e Physalis floridana, que se revelaram ótimas diferenciadoras para os isolados VEL e P21, respectivamente. Provavelmente os 11 isolados de PVX, estudados neste trabalho, possuem a mesma origem que os isolados dos grupos 1 e 3.

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.
