“…Aside from insect vector transmission, BSV is also transmitted through seeds [96], but because endogenous BSV sequences occur in the nuclear genome of most cultivars [91], seed transmission is difficult to show. Some of the economically important badaviruses are the Banana streak virus (BSV) [97,98], Cacao swollen shoot virus (CSSV) [99], Canna yellow mottle virus (CaYMV) [100], Dioscorea bacilliform AL virus (DBV) [101,102], Kalanchoe top-spotting virus (KTSV) [103], Piper yellow mottle virus (PYMV) [104], Schefflera ringspot virus (SRV) [105], Sugarcane bacilliform virus (SCBV) [100], and Citrus yellow mosaic virus (CYMV) [106].…”

Mealybug Wilt of Pineapple and Associated Viruses

et al. 2018

Mealybug wilt of pineapple (MWP) is a disease of pineapple that has a long history in Hawaii, but is present throughout the world where pineapples are grown in tropical regions. The disease has an interesting etiology that is poorly understood but involves an association with virus particles, mealybug vectors, and ants which spread the mealybug vectors. Several distinct pineapple mealybug wilt-associated virus (PMWaV) species have been identified thus far with potential further member species yet to be characterized. Pineapple mealybug wilt-associated viruses are member species of the Ampelovirus genus of the Closteroviridae family. Ampeloviruses are split into two subgroups, subgroup I and subgroup II. PMWaV-2 is a subgroup II member, and these have a longer and more complex genome with additional genes on the 3' terminus of the RNA genome compared to subgroup I ampeloviruses. PMWaV-2, along with the presence of mealybug vectors, have been shown to be necessary factors in symptom development in Hawaii. Some of these extra genes in the 3' of PMWaV-2 have recently been shown to function as silencing suppressors, and may play a role in the virulence of PMWaV-2 and symptom development. In other regions of the world, reports of symptomatic plants without PMWaV-2 infection, but with PMWaV-1, -3 or some combination, contradict the requirement of PMWaV-2 for symptom development in MWP. It is possible that further, uncharacterized PMWaVs may be present in symptomatic pineapple plants that test negative for PMWaV-2, explaining the inconsistency in symptom development. More research is necessary to explore the confusing etiology of the MWP disease, and to perhaps shed light upon the symptom development.

“…The yellow mottle disease (also known as stunt disease) of black pepper ( Piper nigrum ) caused by the badnavirus, Piper yellow mottle virus (PYMoV) is reported in Brazil, China, India, Indonesia, Malaysia, Philippines, Sri Lanka, Thailand, and Vietnam [ 45 , 46 , 47 , 48 , 49 ]. The disease is characterized by chlorotic flecks, mild to severe mottles, and brittle, leathery, deformed, and reduced leaf size ( Figure 2 ).…”

“…Thus, soil and plant health play an important role in the symptom expression and the severity of the disease. Lockhart et al [ 45 ] for the first time reported the association of a distinct badnavirus with yellow mottle disease affecting black pepper from Indonesia, Malaysia, Philippines, and Thailand and named it Piper yellow mottle virus (PYMoV) based on bacilliform virus particles, transmission by mealybug, its weak serological relationship with other badnaviruses, and its partial nucleotide sequence of the reverse transcriptase (RT)/RNase H region of the virus. Later association of PYMoV with black pepper was reported in Brazil [ 51 ], Sri Lanka [ 46 ], India [ 47 ], Vietnam, and China [ 48 ].…”

“…PYMoV showed 39% to 56% identity with other badnaviruses and phylogenetic analysis using either the complete genome or conserved region of the RT/RNaseH showed grouping of all PYMoV isolates into a single cluster separated from other badnaviruses. Black pepper is a perennial and propagated by vegetative means; the primary spread of the virus occurs through vegetative means while secondary spread in the field happens through semi-persistent transmission by mealybugs ( Ferrisia virgata and Planococcus citri ) and black pepper lace bug [ 45 , 46 , 47 ]. Methods such as PCR, real-time PCR, loop-mediated isothermal amplification (LAMP), and recombinase polymerase amplification (RPA) are reported for the identification of virus-free mother plants for propagation [ 57 , 58 , 59 , 60 ].…”

Emerging and Re-Emerging Diseases Caused by Badnaviruses

New and emerging plant diseases are caused by different pathogens including viruses that often cause significant crop losses. Badnaviruses are pararetroviruses that contain a single molecule of ds DNA genome of 7 to 9 kb in size and infect a large number of economically important crops such as banana and plantains, black pepper, cacao, citrus, grapevine, pineapple, sugarcane, sweet potato, taro, and yam, causing significant yield losses. Many of the species in the genus have a restricted host range and several of them are known to infect a single crop. Combined infections of different virus species and strains offer conditions that favor the development of new strains via recombination, especially in vegetatively propagated crops. The primary spread of badnaviruses is through vegetative propagating materials while for the secondary spread, they depend on insects such as mealybugs and aphids. Disease emerges as a consequence of the interactions between host and pathogens under favorable environmental conditions. The viral genome of the pararetroviruses is known to be integrated into the chromosome of the host and a few plants with integrants when subjected to different kinds of abiotic stress will give rise to episomal forms of the virus and cause disease. Attempts have been made to develop management strategies for badnaviruses both conventionally and using precision breeding techniques such as genome editing. Until 2016 only 32 badnavirus species infecting different crops were known, but in a span of six years, this number has gone up to 68. The current review highlights the emerging disease problems and management options for badnaviruses infecting economically important crops.

“…Badnaviruses (Family: Caulimoviridae; Genus: Badnavirus) is characterized by their non-enveloped bacilliform DNA viruses with a monoportite genome containing about 7.2 to 9.2 kb of double stranded DNA with three to seven open reading frames [1]. Badnavirus infects numerous crops including sugarcane, citrus, banana, and piper species [2][3][4][5][6]. The infection of Badnavirus leads to a variety of symptoms in plants, ranging from an asymptomatic to stunting in their growth.…”

Badnavirus, a member of the Caulimoviridae family, is known to cause economic losses in various crops, including Piper spp. However, there is no information on Badnavirus infection in Piper spp. and its distribution in Java. The aim of this study was to determine the presence of Badnavirus in Piper spp and its distribution in Java. The research included field observation, sample collection, and virus detection by PCR. A total of 96 samples of Piper spp. were collected from West Java, Central Java and Yogyakarta Province. The degenerate primer Badna FP and RP were successfully used to amplify DNA fragments of 600 bp from leaf samples. Within the Java region, six species of Piper were identified, namely P. betle, P. crocatum, P. retrofractum, P. sarmentosum, P. cubeba, and P. colubrinum. These species were found in both Bogor and Bogor Regency. In Sleman and Magelang, P. betle, P. crocatum, and P. retrofractum were present, while in Yogyakarta only P. betle and P. crocatum were found. Five species of Piper were infected by Badnavirus, except for P. colubrinum, which remained free from infection. This research was proven that Badnavirus has infected members of Piper spp. and has spread throughout the Java Region.
