“…A study suggests that the taro cultivars of various origin possess little to no resistance to Alomae, as most of the infections lead to plant death [41]. As such, it is vital that the geographical movement of taro planting materials from the Solomon Islands and Papua New Guinea is controlled [4,23,29,41].…”

“…Taro viruses, which could lead to diseases, damage the crop yield and sometimes lead to plant death [17]. Multiple viruses have been found to infect taro, including the four main viruses; Dasheen mosaic virus (DsMV) , Taro bacilliform virus (TaBV) , Colocasia bobone disease virus (CBDV) , and Taro vein chlorosis virus (TaVCV) [5,6,8,9,17,18,19,20,21,22,23,24,25,26] that this review will centre on. This review will also mention a relatively new virus Taro bacilliform CH virus (TaBCHV) [17,19,27].…”

Taro is an important crop in parts of the world, especially in the Pacific Islands. Like all plants, it is also susceptible to virus infections that could result in diseases, which negatively affects the source of food and trade revenue. Understanding the biology of taro viruses could improve current knowledge regarding the relationship between viruses and taro, thus allowing for a better approach towards the management of the diseases that are associated with them. By compiling and discussing the research on taro and its four major viruses (Dasheen mosaic virus, Taro bacilliform virus, Colocasia bobone disease virus, and Taro vein chlorosis virus) and a relatively new one (Taro bacilliform CH virus), this paper explores the details of each virus by examining their characteristics and highlighting information that could be used to mitigate taro infections and disease management.

“…provides a staple food source for millions of people in Africa, South America, Asia, and the Pacific as well as having significant cultural and economic importance (Bourke and Vlassak, ; Sukal et al . , ). While Africa accounts for 95% of total world production, predominated by Dioscorea rotundata‐cayenensis (FAOSTAT, ), yam is also very important in the Pacific, where D. alata and D. esculenta are the dominant species (Kenyon et al .…”

Characterization and genetic diversity of Dioscorea bacilliform viruses present in a Pacific yam germplasm collection

et al. 2020

Yam is an important food staple in many Pacific Island countries, but its production is limited by several factors including virus infection. The presence of viruses also hinders the exploitation of the crop by restricting the international dissemination of yam germplasm due to quarantine concerns. In this study, a total of 224 yam accessions present in the Pacific germplasm collection at SPC‐CePaCT, Fiji, were tested for the presence of badnaviruses using a combination of rolling circle amplification (RCA) and sequencing. Of these, 35 tested positive for either Dioscorea bacilliform AL virus (DBALV) or Dioscorea bacilliform AL virus 2 (DBALV2). DBALV was only detected in samples from Vanuatu and Tonga, while DBALV2 was restricted to Papua New Guinean samples. Ten complete genome sequences of DBALV and DBALV2 were obtained and pairwise comparison of the partial reverse transcriptase/ribonuclease H (RT/RNase H)‐coding sequence revealed identities ranging from 89% to 100% and 92% to 100%, respectively. The results suggest that DBALV and DBALV2 are the prevalent badnavirus species infecting yams in the Pacific region.

“…Yam production is adversely affected by several constraints including biotic stresses such as pests and diseases, mainly viruses, bacteria and fungi, as well as abiotic stresses like decline in soil fertility [ [7] , [8] , [9] ]. Different species of viruses belonging to the genera Aureusvirus, Badnavirus, Cucumovirus, Macluravirus, Potyvirus, Potexvirus and Tobamovirus have been reported threatening yams production worldwide [ [10] , [11] , [12] , [13] , [14] ].…”
