Reduction of Carbon Assimilation and Water Use Efficiency in Groundnut Ringspot Virus (GRSV)-Infected Groundnut Varieties

European Journal of Biology and Biotechnology
Groundnut (Arachis hypogaea L.) production is threatened by the advent of many emerging pests and diseases, key among them being Groundnut ringspot virus (GRSV). The numerous alternative host crops of the virus make its control particularly difficult, resulting in heightened virus transmission risk and increased yield loss.

Current Status and Prospects of Virus Elimination in Economically Important Crops of Ethiopia Through Tissue Culture Practices: A Review

Advances in Agriculture, Volume 2025, Issue 1, 2025.
Currently, huge crop losses in countries’ genetic resources result from emerging or re‐emerging plant viral diseases, making food security a constant challenge. A critical examination of recent tissue culture practices in Ethiopia reveals numerous limitations that have contributed to the limited advancements of plant tissue culture (PTC) techniques ...

Expression of a modified nucleocapsid-protein of Tomato spotted wilt virus (TSWV) confers resistance against TSWV and Groundnut ringspot virus (GRSV) by blocking systemic spread.

Molecular plant pathology, 2012
SUMMARY Tobacco transformed with a construct comprising the nucleocapsid-protein (N) gene of Tomato spotted wilt virus (TSWV) and the 5' non-translated leader sequence of Plum pox virus (PPV) as a translation enhancer displays unusually broad resistance against tospoviruses. Contrary to expectations, the transgenic plants did not express a higher level

Insect Vectors of Plant Viruses: Host Interactions, Their Effects, and Future Opportunities

Advances in Agriculture, Volume 2024, Issue 1, 2024.
Plant viruses are endocellular, and they multiply inside their host plant cells. Outside of the host cells, they are acellular and cannot multiply and move to their hosts for reproduction. Plant virus use insect vectors to transmit and distribute from the infected farm to the next health plant or farms—especially the orders of Hemiptera, Thysanoptera ...

Commodity risk assessment of Petunia spp. and Calibrachoa spp. unrooted cuttings from Guatemala

EFSA Journal, Volume 22, Issue 1, January 2024.
Abstract The European Commission requested the EFSA Panel on Plant Health to evaluate the probability of entry of pests (likelihood of pest freedom at entry), including both, regulated and non‐regulated pests, associated with unrooted cuttings of the genera Petunia and Calibrachoa produced under physical isolation in Guatemala.

Diverging affinity of tospovirus RNA silencing suppressor proteins, NSs, for various RNA duplex molecules [PDF]

, 2010
The tospovirus NSs protein was previously shown to suppress the antiviral RNA silencing mechanism in plants. Here the biochemical analysis of NSs proteins from different tospoviruses, using purified NSs or NSs containing cell extracts, is described.
