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 ...

A genome-wide pairwise-identity-based proposal for the classification of viruses in the genus Mastrevirus (family Geminiviridae) [PDF]

Archives of Virology, 2013
Recent advances in the ease with which the genomes of small circular single-stranded DNA viruses can be amplified, cloned, and sequenced have greatly accelerated the rate at which full genome sequences of mastreviruses (family Geminiviridae, genus Mastrevirus) are being deposited in public sequence databases.

First Report of Saffron-Associated Mastrevirus 1 from Saffron in Iran

Plant Disease
In spring 2022, 40 leaf samples of saffron plants harboring a wide variety of symptoms, including curling, yellowing, mosaic, dwarfing and leaf malformation were collected from three Khorasan provinces in Iran. These samples were processed using the virion-associated nucleic acid-based metagenomics approach (Moubset et al., 2022).
