Potato virus Y (PVY) is a plant pathogenic virus of the family Potyviridae, and one of the most important plant viruses affecting potato production. PVY infection of potato plants results in a variety of symptoms depending on the viral strain. The mildest of these symptoms is production loss, but the most detrimental is 'potato tuber necrotic ringspot disease' (PTNRD). Necrotic ringspots render potatoes unmarketable and can therefore result in a significant loss of income. PVY is transmissible by aphid vectors but may also remain dormant in seed potatoes. This means that using the same line of potato for production of seed potatoes for several consecutive generations will lead to a progressive increase in viral load and subsequent loss of crop.
Short peptide PRP1, and preparation method and use thereof
The present application discloses a short peptide PRPl, and a preparation method and a use thereof, belonging to the technical field of genetic engineering. Through research, the present application identifies a short peptide derived from an unknown protein that regulates tobacco resistance to potato virus Y (PVY) disease, named PVY resistance peptide (PRP 1). Its amino acid sequence is ATKHIVGSIVAS, and the short peptide PRPl is prepared by chemical synthesis. The use of the short peptide injection during the seedling stage of tobacco may effectively reduce the amount of PVY virus and improve the resistance of tobacco to PVY disease.

Molecular markers for detecting the PVR4 gene of potato virus Y resistance and its application
This invention provides a molecular marker for detecting the PVR4 gene, a resistance gene against Potato Virus Y, and its application, belonging to the field of genetic engineering technology. The molecular marker is the TC base at 4714-4715 bp of the CM334 pepper variety (NCBI accession number KT359375.1). This invention also provides primers and a kit based on the molecular marker. PCR amplification and electrophoresis detection enable rapid and accurate screening of pepper varieties carrying the PVR4 gene against Potato Virus Y. The molecular marker described in this invention plays an important role in detecting the PVR4 gene against Potato Virus Y in peppers or in breeding disease-resistant pepper varieties.

Application of NtSGRL1-related biological product in tobacco virus resistance
PendingCN122071719Areduce accumulationFermentationVector-based foreign material introductionNicotiana tabacumTomato spotted wilt virus
The invention belongs to the technical field of plant genetic engineering, and particularly relates to application of an NtSGRL1-related biological product in tobacco antivirus, and the nucleotide sequence of the NtSGRL1 is shown as SEQ ID NO.1. The invention also relates to an application of the NtSGRL1-related biological product in tobacco antivirus. According to the invention, a CRISPR-Cas9 mediated common tobacco NtSGRL1 knockout strain Ntsgrl1 is created through genetic transformation, and four main tobacco viruses of tomato yellow leaf curl virus, tobacco mosaic virus, potato Y virus and tomato spotted wilt virus are respectively adopted to inoculate the obtained Ntsgrl1 function deletion mutant strain. Disease resistance identification results show that compared with wild and overexpression strains, the Ntsgrl1 mutant strain shows broad-spectrum and significantly enhanced resistance to four tested viruses, which is specifically embodied in that the system symptom development is significantly inhibited, and the virus accumulation in the plant is significantly reduced.
