| identification and molecular characterization of a new potyvirus from panax notoginseng. | a potyvirus causing distortion and mosaic symptoms in the herbal plant sanqi (panax notoginseng) was isolated from yunnan province, china, and the complete nucleotide sequence of one isolate and the partial sequences of two other isolates were determined. the viral rna genome comprised 9,750 nt excluding the 3'-terminal poly(a) tail, with the capacity to encode a single polyprotein of 3,089 amino acids. phylogenetic analysis with other completely sequenced potyviruses revealed that the virus in ... | 2010 | 20446003 |
| oligonucleotide microarray with a minimal number of probes for the detection and identification of thirteen genera of plant viruses. | a major challenge facing agriculture at present is the development of techniques that can screen field samples and other plant materials simultaneously for the presence of many viruses. microarray techniques show promise in this regard, as their high throughput nature can potentially detect a range of viruses using a single test. in this paper we present an array that can detect a wide spectrum of 169 plant virus species from 13 different genera. the array was constructed using an automated prob ... | 2010 | 20304013 |

| chemical assessment of roots of panax notoginseng in china: regional and seasonal variations in its active constituents. | root of panax notoginseng (radix notoginseng, sanqi) is a well-known traditional chinese medicine and is mainly cultivated in wenshan of yunnan, china. the active constituents include saponin, dencichine, flavonoid, and polysaccharide; however, the levels of these components vary in different geographical regions of growth and also show a seasonal variation. by using high-performance liquid chromatography and spectrophotometry, the contents of notoginsenoside r1, ginsenoside r(g1), r(b1), r(d), ... | 2003 | 14705886 |
| [observation of blooming habits of panax notoginseng]. | this paper reported the whole process of blooming habits of panax notoginseng and pollens scattering regularities in wenshan, yunnan province. it can provide reference for the pollenation of hybridization. | 2003 | 14528688 |
