| nine novel dna components associated with the foorkey disease of large cardamom: evidence of a distinct babuvirus species in nanoviridae. | foorkey disease is a serious constraint to the production of large cardamom (amomum subulatum, family zingiberaceae). the disease is characterized by profuse proliferation of excessive stunted shoots, which makes the clump totally unproductive. the disease has been known in india since 1936 but the complete genome of the virus had not yet been characterized. in a preliminary study, an associated virus tentatively named as cardamom bushy dwarf virus (cbdv) was identified based on the partial sequ ... | 2013 | 24091364 |
| cardamom bushy dwarf virus infection in large cardamom alters plant selection preference, life stages, and fecundity of aphid vector, micromyzus kalimpongensis (hemiptera: aphididae). | cardamom bushy dwarf virus (cbdv) causes foorkey disease of large cardamom (ammomum subulatum roxburgh) in the eastern sub-himalayan mountains. although the aphid micromyzus kalimpongensis basu (hemiptera: aphididae) is known as a vector of cbdv, its behavior in dissemination of cbdv has not been investigated. in the present study, m. kalimpongensis was observed to colonize in higher number on cbdv-infected large cardamom plants compared with the healthy plants in the several plantations in sikk ... | 2016 | 26518036 |
| cryptic diversity and habitat partitioning in an economically important aphid species complex. | cardamom bushy dwarf virus (cbdv) is an aphid-borne nanovirus which infects large cardamom, amomum subulatum (zingiberaceae family), in the himalayan foothills of northeast india, nepal and bhutan. two aphid species have been reported to transmit cbdv, including pentalonia nigronervosa and micromyzus kalimpongensis (also described as pentalonia kalimpongensis). however, p. nigronervosa was recently split into two species which exhibit different host plant affiliations. whilst p. nigronervosa pri ... | 2015 | 25535945 |
| identifying geographic hot spots of reassortment in a multipartite plant virus. | reassortment between different species or strains plays a key role in the evolution of multipartite plant viruses and can have important epidemiological implications. identifying geographic locations where reassortant lineages are most likely to emerge could be a valuable strategy for informing disease management and surveillance efforts. we developed a predictive framework to identify potential geographic hot spots of reassortment based upon spatially explicit analyses of genome constellation d ... | 2014 | 24944570 |
| asymmetric patterns of reassortment and concerted evolution in cardamom bushy dwarf virus. | nanoviruses are single-stranded dna (ssdna) plant viruses which have multipartite genomes consisting of discrete, individually encapsidated components. this multipartite strategy may lead to high rates of reassortment, whereby entire genome components are exchanged among different strains. however, few studies have explored the extent to which reassortment shapes the genetic diversity of nanovirus populations. here we present an extensive analysis of reassortment among 163 cardamom bushy dwarf v ... | 2014 | 24613431 |
