Yam mosaic virus (YMV) is the most important virus infecting both cultivated and wild yam species worldwide. The virus is transmitted by aphids in a non-persistent manner, as well as through infected plant material from generation to generation. (Ita EE, Uyoh EA, Nakamura I, Ntui VO. Efficient elimination of Yam mosaic virus (YMV) from white yam (Dioscorea rotundata Poir.) by cryotherapy of axillary buds. S Afr J Bot. 2020 May;130:123-129. doi: 10.1016/j.sajb.2019.12.022. PMID: 32565604; PMCID: PMC7291922.)
A sound spectrum is a representation of a sound – usually a short sample of a sound – in terms of the amount of vibration at each individual frequency. It is usually presented as a graph of either power or pressure as a function of frequency. (https://newt.phys.unsw.edu.au/jw/sound.spectrum.html)
A small molecular RNA, transmissible in plants, without an extracellular protein component or translation capacity and which can be pathogenic. It is composed of naked, single-stranded low-molecular RNA (MW 80 000 - 130 000) which utilizes only host components for its replication. They exist in solution as rod-like structures arranged in a series of short base-paired and non-base-paired regions. (C. N. Roistacher, “Graft-Transmissible Diseases of Citrus. Handbook for Detection and Diagnosis,” FAO, Rome, 1991, p. 286.)
An aerial plant part, often a branchlet, that is grafted onto the root bearing part (stock/root-stock) of another plant. (Guidelines on Grafting, Air-Layering and Cuttings, FAO 1993)
