Vegetative propagation of potato allows the dissemination of viruses that can cause drastic drops in tuber yield. Potato virus Y (PVY) is one of the most important viruses of potato due to the non-persistent mode of transmission through vector insects. Genetic resistance is the recommended control measure since the chemical control of vector insects is not effective. This study aimed to identif...

Virus induced gene silencing (VIGS) is increasingly used to generate transient loss-of-function assays and has potential as a powerful reverse-genetics tool in functional genomic programs as a more rapid alternative to stable transformation. A previously described potato virus X (PVX) VIGS vector has been shown to trigger silencing in the permissive host Nicotiana benthamiana. This paper demons...

We found that Sweet potato feathery mottle virus (SPFMV) P1, a close homologue of Sweet potato mild mottle virus P1, did not have any silencing suppressor activity. Remodeling the Argonaute (AGO) binding domain of SPFMV P1 by the introduction of two additional WG/GW motifs converted it to a silencing suppressor with AGO binding capacity. To our knowledge, this is the first instance of the trans...

A series of experiments was conducted using membrane sachets containing MP148 diet or phosphate-buffered sucrose with and without purified Potato leafroll virus to determine if direct encounter with the virus would arrest the aphid, Myzus persicae (Sulzer) (Homoptera: Aphididae). In only two out of 36 tests were there significantly more aphids settled on sachets containing the virus. In all oth...

The cell wall provides the structure of the plant, and also acts as a barier against biotic stress. The vein necrosis strain of Potato virus Y (PVYNTN) induces necrotic disease symptoms that affect both plant growth and yield. Virus infection triggers a number of inducible basal defense responses, including defense proteins, especially those involved in cell wall metabolism. This study investig...

Potato is one of the most important staple crops in both developed and developing countries of the world. Potato genetic resources are a prerequisite for potato breeding in both conventional and genetic engineering programmes. Cryopreservation has long been considered an ideal means for the long-term conservation of plant genetic resources. This review provides comprehensive information on vari...

PMTV (Potato Mop-Top Virus ) and PAMV Aucuba Mosaic Virus) are new damaging pathogens of potato crop in Romania. They can cause serious reduced yield decrease the tuber’s quality. In case these viruses, infected plants do not allways show signs disease symptoms depend on cultivar, virus strain environment. infection material produce spraing tubers sensitive varieties. causes heavy losses northe...
