Comparative small RNA profiles of beet mosaic virus (BtMV), beet mild yellowing virus (BMYV) and beet yellows virus (BYV) infected Nicotiana benthamiana and Beta vulgaris [PDF]

Virus Research
Plants are constantly challenged by viral pathogens that can limit growth and reduce yield. A key component of the plant innate immunity is RNA silencing, in which viral double-stranded RNA (dsRNA) intermediates are recognised and processed into virus ...

The citrus tristeza virus p33 protein functions as a viroporin. [PDF]

PLoS Pathogens
Viroporins are viral proteins that form ion channels in the membranes of the host and, thus, alter the host ion homeostasis to create more favorable environments for the virus.

Citrus tristeza virus p20 suppresses antiviral RNA silencing by co-opting autophagy-related protein 8 to mediate the autophagic degradation of SGS3. [PDF]

PLoS Pathogens
Viruses exploit autophagy to degrade host immune components for their successful infection. However, how viral factors sequester the autophagic substrates into autophagosomes remains largely unknown.

Systemic and Phloem-Specific Protein Targeting by High Affinity Nanobodies Expressed From a Plant RNA Virus Vector. [PDF]

Mol Plant Pathol
This proof‐of‐concept study, with validation by pull‐down assays and FRET‐FLIM measurements, establishes a platform for targeting proteins in the phloem by nanobodies expressed from a viral vector. ABSTRACT The emergence of nanobodies (Nbs) has kindled an avid interest for their use in genetic engineering and plant biotechnology.

Transcriptomic alterations in the sweet orange vasculature correlate with growth repression induced by a variant of citrus tristeza virus

Frontiers in Microbiology, 2023
Citrus tristeza virus (CTV, family Closteroviridae) is an economically important pathogen of citrus. CTV resides in the phloem of the infected plants and induces a range of disease phenotypes, including stem pitting and quick decline as well as a number ...

High-Throughput Sequencing Detects a Viral Complex in <i>Agave Tequilana</i> Plants. [PDF]

Adv Virol
Agave tequilana Weber var. Azul is one of the most economically important species in Mexico because of its use in the production of tequila. Recently, young agave plants in commercial plantations in the state of Jalisco and agave ornamental plants have been observed to have symptoms of yellow streaks and mottle like those caused by viruses.

The Intriguing Conundrum of a Nonconserved Multifunctional Protein of Citrus Tristeza Virus That Interacts with a Viral Long Non-Coding RNA

Viruses, 2021
Citrus tristeza virus (CTV), the largest non-segmented plant RNA virus, has several peculiar features, among which is the production of a 5′-terminal long non-coding RNA (lncRNA) termed low-molecular-weight tristeza 1 (LMT1). In this study, we found that

Walking Together: Cross-Protection, Genome Conservation, and the Replication Machinery of Citrus tristeza virus

Viruses, 2020
“Cross-protection”, a nearly 100 years-old virological term, is suggested to be changed to “close protection”. Evidence for the need of such change has accumulated over the past six decades from the laboratory experiments and field tests conducted by ...

Beet mosaic virus expression of a betalain transcription factor allows visual virus tracking in Beta vulgaris

Molecular Plant Pathology, Volume 24, Issue 10, Page 1319-1329, October 2023., 2023
The BvMYB1 transcription factor activates betalain biosynthesis in members of Caryophyllales and, by virus‐derived expression, allows visualization of virus spread by the naked eye. Abstract In the field of plant virology, the usage of reverse genetic systems has been reported for multiple purposes.
