| comparison of the nucleotide sequences of the 3'-terminal regions of one aphid and two non-aphid transmissible isolates of potato a potyvirus. | the sequences of the 3'-terminal 1145 nucleotides of two non-aphid transmissible (nat) isolates (ali and juliniere) and one aphid transmissible (at) isolate (rouge) of potato virus a (pva) rna were determined. those sequences contained the complete coding region of the coat protein (cp) followed by a 3'-nontranslated region (3'-ntr) of 225 (ali and juliniere) and 227 (rouge) nucleotides. the obtained sequences were compared to those of the 3'-regions of four published pva isolates and a virus de ... | 1996 | 8774682 |
| comparison of the complete sequences of five different isolates of potato virus a (pva), genus potyvirus. | the complete nucleotide (nt) and deduced amino acid (aa) sequences of isolates ali, u, her (from potato, solanum tuberosum) and tammv (from tamarillo, solanum betacea) of potato virus a (pva, genus potyvirus) were determined and compared with the previously reported sequence of pva isolate b11. most parts (proteins) of the polyprotein showed over 95% aa sequence similarity. the cylindrical inclusion (ci) protein and the 6k 1 protein were the most conserved proteins among the five isolates. tammv ... | 1999 | 10664389 |
| mapping of viral genomic regions important in cross-protection between strains of a potyvirus. | cross-protection was tested between potato and tobacco strains of potato virus a, a member of the genus potyvirus (pva), in tobacco plants. cross-protection was effective only at the initiation of infection. the potato strains provided only weak cross-protection against the tobacco strain, whereas the tobacco strain provided strong cross-protection against potato strains. the tamarillo strain (tammv) showed cross-protection phenotypes mostly resembling those of the potato strains. chimera of the ... | 2002 | 12118884 |
| biological, serological, and molecular differences among isolates of potato a potyvirus. | abstract sequences of the coat protein (cp) and 3'-end nontranslated region (3'ntr) of 13 isolates and the helper component proteinase (hc) of nine isolates of potato a potyvirus (pva) were determined and compared with the eight previously determined pva cp and 3'ntr sequences and one hc sequence. cp amino acid (aa), 3'ntr nucleotide, and hc aa sequence identities were 92.9, 93.4, and 94.8%, respectively. sequence data, serological tests, and the necrotic local lesions induced in the leaves of t ... | 1998 | 18944954 |
| 'candidatus liberibacter solanacearum', associated with plants in the family solanaceae. | a liberibacter (isolate nz082226) was detected in a symptomatic tomato plant and subsequently in five other members of the family solanaceae: capsicum, potato, tamarillo, cape gooseberry and chilli. phylogenetic analyses of the 16s rrna gene sequence, the deduced amino acid sequence of the rplj gene and a partial nucleotide sequence of the beta operon indicated that isolate nz082226 represents a novel candidate species of 'candidatus liberibacter', for which the name 'candidatus liberibacter sol ... | 2009 | 19620372 |
| physical and chemical characteristics of golden-yellow and purple-red varieties of tamarillo fruit (solanum betaceum cav.). | golden-yellow and purple-red tamarillos (solanum betaceum cav.) cultivated in ecuador were studied for their physical properties, proximate composition, ph, degrees brix, acidity, sugars, organic acids, minerals, vitamin c and beta-carotene content in the edible part. results were compared with those for spanish fruits. the golden-yellow and purple-red ecuadorian fruits were larger (107 and 188 g) than the respective spanish fruits (43 and 63 g), softer but generally similar in chemical composit ... | 2009 | 19657848 |
| radical scavenging capacity and antimutagenic properties of purified proteins from solanum betaceum fruits and solanum tuberosum tubers. | in this study, antioxidant activities in free-radical-mediated oxidative systems and the genotoxic/antigenotoxic effects of two proteins with molecular mass around 17 kda, purified from solanum betaceum fruits (cyphomine) and solanum tuberosum tubers (solamarine), were investigated. both proteins inhibited uric acid formation with ic(50) values between 55 and 60 µg/ml, and both proteins were able to reduce oxidative damage by scavenging hydroxyl radicals and superoxide anion in a dose-dependent ... | 2011 | 21749141 |
| use of spent osmotic solutions for the production of fructooligosaccharides by aspergillus oryzae n74. | in the food industry, osmotic dehydration can be an important stage to obtain partially dry foodstuffs. however, the remaining spent osmotic solution at the end of the process could become a waste with an important environmental impact due to the large amount of organic compounds that it might contain. since one of the most important osmotic agents used in osmotic dehydration is sucrose, this spent osmotic solution could be used to be biotransformed to produce fructooligosaccharides by a fructos ... | 2014 | 23744119 |
| genome sequence of a virus isolate from tamarillo (solanum betaceum) in colombia: evidence for a new potyvirus. | based on the results of a deep sequencing transcriptome study of tamarillo (solanum betaceum), we report the genome sequence of a virus from this host plant. since this probably represents a new member of the genus potyvirus, the name tamarillo leaf malformation virus (talmv) has been proposed. phylogenetic analysis reveals that talmv is the closest relative of colombian datura virus (cdv), followed by three other potyviruses: tobacco etch virus, potato virus a and tobacco vein mottling virus. t ... | 2015 | 25466572 |
| hplc-pda-ms/ms of anthocyanins and carotenoids from dovyalis and tamarillo fruits. | anthocyanins and carotenoids are natural pigments responsible for the color of vegetables and fruits, and they are also bioactive compounds, both demonstrating important biological, therapeutic, and preventative properties. considering the biodiversity of edible fruits, high performance liquid chromatography coupled to photodiode array and mass spectrometry detectors (hplc-pda-ms) was used to establish the composition of carotenoids and anthocyanins from dovyalis and tamarillo fruits. ten anthoc ... | 2007 | 17927197 |
| genetic diversity of phytophthora infestans in the northern andean region. | phytophthora infestans (mont.) de bary, the causal agent of potato late blight, is responsible for tremendous crop losses worldwide. countries in the northern part of the andes dedicate a large proportion of the highlands to the production of potato, and more recently, solanaceous fruits such as cape gooseberry (physalis peruviana) and tree tomato (solanum betaceum), all of which are hosts of this oomycete. in the andean region, p. infestans populations have been well characterized in ecuador an ... | 2011 | 21303555 |
| characterization of colletotrichum isolates from tamarillo, passiflora, and mango in colombia and identification of a unique species from the genus. | abstract this study was conducted to identify the species of colletotrichum infecting tamarillo, mango, and passiflora in colombia and to assess whether cross-infection between host species is occurring. isolates of colletotrichum spp. from tamarillo (n = 54), passiflora (n = 26), and mango (n = 15) were characterized by various molecular methods and by morphological criteria. morphological characterization grouped the tamarillo isolates as c. acutatum and the passiflora and mango isolates as c. ... | 2003 | 18942980 |
| sequence-, tissue-, and delivery-specific targeting of rna during post-transcriptional gene silencing. | transgenic nicotiana benthamiana plants expressing an untranslatable version of the coat protein (cp) gene from the tamarillo mosaic virus (tamv) were either resistant to tamv infection or recovered from infection. these phenotypes were the result of a post-transcriptional gene silencing (ptgs) mechanism that targeted tamv-cp sequences for degradation. the tamv-cp sequences were degraded when present in the wild-type tamv potyvirus, in transgene mrna, or in chimeric viral vectors based on white ... | 2002 | 12182332 |
| characterization of ntpase, rna-binding and rna-helicase activities of the cytoplasmic inclusion protein of tamarillo mosaic potyvirus. | the 66-kda cytoplasmic inclusion protein of tamarillo mosaic potyvirus was purified to near homogeneity using organic solvent clarification, differential centrifugation and sucrose density gradient centrifugation. atpase and gtpase activities were shown to co-purify with the 66-kda protein. atpase activity was stimulated up to fivefold in the presence of 20 microm poly(a). the km value for atp hydrolysis (18 microm), was minimally affected upon addition of poly(a). in contrast, the vmax value fo ... | 1994 | 7925384 |
