Plants have specialized mechanisms for transporting mRNAs through plasmodesmata, and these mechanisms are thought to be used by RNA viruses to spread from one cell to another. [2] . Plant defenses against viral infection include, among other measures, the use of siRNA in response to dsRNA. [3] .
5 de jun. de 2023 · According to the evolutionary relationships between hallmark viral genes, plant viruses are classified into two realms, Monodnaviria and Riboviria, which include single-strand DNA (ssDNA) viruses and RNA viruses, respectively.
5 de mar. de 2021 · In this study, the authors showed that mixed virus infections of DNA and RNA viruses, begomoviruses, a potyvirus, and a crinivirus in individual plants could be identified without initial knowledge by employing Illumina sequencing platforms .
1 de ene. de 2020 · Plant infection by RNA viruses is initiated with the association of viral RNA genome with ER or with membranes of organelles connected to the ER, and local translation produces virus factors that form interaction networks among themselves as well as with host proteins to form a VRC.
9 de feb. de 2024 · This review discusses the significance of these strategies in preventing aphid-mediated plant virus transmission, emphasizing the crucial role of meticulous dsRNA design for effective viral RNA targeting while minimizing harm to plant RNA.
16 de jun. de 2022 · RNA silencing is a well-established antiviral immunity system in plants, in which small RNAs guide Argonaute proteins to targets in viral RNA or DNA, resulting in virus repression.
16 de jun. de 2023 · Here, we report that NPR1 plays a pivotal role in restricting compatible infection by turnip mosaic virus, a member of the largest plant RNA virus genus Potyvirus, and that such resistance is...
