Organ-specific differences in endogenous phytohormone and antioxidative responses in potato upon PSTVd infection

Journal of Plant Physiology, 2019
Although structurally simple, viroids can trigger numerous changes in host plants and cause loss of yield in agronomically important crops. This study investigated changes in the endogenous status of phytohormones and antioxidant enzyme activity in Solanum tuberosum cv. Désirée in response to Potato spindle tuber viroid (PSTVd) infection.

The root‐knot nematode effector MiEFF12 targets the host ER quality control system to suppress immune responses and allow parasitism

Molecular Plant Pathology, Volume 25, Issue 7, July 2024.
The Meloidogyne incognita effector MiEFF12 targets endoplasmic reticulum‐resident proteins and corrupts their function in the host immune response to promote parasitism. Abstract Root‐knot nematodes (RKNs) are microscopic parasitic worms able to infest the roots of thousands of plant species, causing massive crop yield losses worldwide.

Global Analysis of Tomato Gene Expression During Potato spindle tuber viroid Infection Reveals a Complex Array of Changes Affecting Hormone Signaling

Molecular Plant-Microbe Interactions, 2012
Viroids like Potato spindle tuber viroid (PSTVd) are the smallest known agents of infectious disease—small, highly structured, circular RNA molecules that lack detectable messenger RNA activity, yet are able to replicate autonomously in susceptible plant

Viroid-derived small RNA induces early flowering in tomato plants by RNA silencing [PDF]

, 2018
: Viroid infection often leads to early flowering in the host plant. This report describes the targeting of the FRIGIDA-like protein 3 (FRL3) mRNA in tomato plants by a small RNA derived from the conserved left terminal region of the potato spindle tuber

Tertiary Structural and Functional Analyses of a Viroid RNA Motif by Isostericity Matrix and Mutagenesis Reveal its Essential Role in Replication [PDF]

, 2006
RNA-templated RNA replication is essential for viral or viroid infection, as well as for regulation of cellular gene expression. Specific RNA motifs likely regulate various aspects of this replication.

Potato spindle tuber viroid Strains of Different Pathogenicity Induces and Suppresses Expression of Common and Unique Genes in Infected Tomato

Molecular Plant-Microbe Interactions, 2002
Viroids are the smallest plant pathogens. These RNAs do not encode proteins and are not encapsidated, and yet they can replicate autonomously, move systemically, and cause diseases in infected plants.

A three-dimensional RNA motif mediates directional trafficking of Potato spindle tuber viroid from epidermal to palisade mesophyll cells in Nicotiana benthamiana.

PLoS Pathogens, 2019
Potato spindle tuber viroid (PSTVd) is a circular non-coding RNA of 359 nucleotides that replicates and spreads systemically in host plants, thus all functions required to establish an infection are mediated by sequence and structural elements in the ...
