Transgenic Tobacco Plants Expressing the Potato virus X Open Reading Frame 3 Gene Develop Specific Resistance and Necrotic Ring Symptoms After Infection with the Homologous Virus

Molecular Plant-Microbe Interactions, 2001
Tobacco plants were transformed with the open reading frame 3 gene from Potato virus X (PVX) coding for the p12 protein. Although the transgenic plants exhibited a normal morphological aspect, microscopic examination revealed extensive alterations in ...

The IRE1/bZIP60 Pathway and Bax Inhibitor 1 Suppress Systemic Accumulation of Potyviruses and Potexviruses in Arabidopsis and Nicotiana benthamiana Plants

Molecular Plant-Microbe Interactions, 2016
The inositol requiring enzyme (IRE1) is an endoplasmic reticulum (ER) stress sensor. When activated, it splices the bZIP60 mRNA, producing a truncated transcription factor that upregulates genes involved in the unfolded protein response. Bax inhibitor 1 (

Functional analysis of the 5′ untranslated region of potexvirus RNA reveals a role in viral replication and cell-to-cell movement [PDF]

, 2006
Cell-to-cell movement of potexviruses requires cognate recognition between the viral RNA, the triple gene block proteins (TGBp1–3) and the coat protein (CP).

Molecular characterization of yam virus X, a new potexvirus infecting yams (Dioscorea spp) and evidence for the existence of at least three distinct potexviruses infecting yams

, 2014
The genome of yam virus X (YVX), a new member of the genus Potexvirus from yam (Dioscorea trifida), was completely sequenced. Structural and phylogenetic analysis showed that the closest relative of YVX is nerine virus X.

Promotion of Bamboo mosaic virus accumulation in Nicotiana benthamiana by 5’→3’ exonuclease NbXRN4

Frontiers in Microbiology, 2016
Bamboo mosaic virus (BaMV) has a 6.4-kb (+) sense RNA genome with a 5’ cap and a 3’ poly(A) tail. ORF1 of this potexvirus encodes a 155-kDa replication protein responsible for the viral RNA replication/transcription and 5’ cap formation.
