| resistant germplasm in gossypium species and related plants to rotylenchulus reniformis. | gossypium hirsutum, g. herbaceum, g. arboreum, g. barbadense, wild gossypium spp., hibiscus spp, and other malvaceae were tested in the greenhouse to identify germplasm resistant to rotylenchulus reniformis (rr). host resistance was based on rr egg production per gram of root compared with known g. hirsutum susceptible 'deltapine 16' as check. g. longicalyx and sida rhombifolia were nonhosts. high levels of resistance were found in g. stocksii, g. somalense, and g. barbadense 'texas 110.' other ... | 1984 | 19295892 |
| Begomoviruses infecting weeds in Cuba: increased host range and a novel virus infecting Sida rhombifolia. | As a result of surveys conducted during the last few years to search for wild reservoirs of begomoviruses in Cuba, we detected a novel bipartite begomovirus, sida yellow mottle virus (SiYMoV), infecting Sida rhombifolia plants. The complete genome sequence was obtained, showing that DNA-A was 2622 nucleotides (nt) in length and that it was most closely related (87.6% nucleotide identity) to DNA-A of an isolate of sida golden mosaic virus (SiGMV) that infects snap beans (Phaseolus vulgaris) in Fl ... | 2011 | 21964921 |
| virus-specific adaptations for the production of a pseudorecombinant virus formed by two distinct bipartite geminiviruses from central america. | most whitefly-transmitted geminiviruses possess bipartite genomes comprising dnas a and b. the production of viable pseudorecombinants by reassortment of infectious cloned components is generally limited to isolates/strains of a particular virus. following exchange of cloned genomic components of sida golden mosaic virus from costa rica (sigmv/co) and sida golden mosaic virus from honduras (sigmv/ho(yv)), the pseudorecombinant viruses were infectious in various plant species. three dna b compone ... | 2000 | 10936098 |
| anti-proliferative activities on hela cancer cell line of thai medicinal plant recipes selected from manosroi ii database. | the thai/lanna medicinal plant recipe database "manosroi ii" contained the medicinal plant recipes of all regions in thailand for the treatment of various diseases including anti-cancer medicinal plant recipes. | 2012 | 22626926 |
| a novel begomovirus isolated from sida contains putative cis- and trans-acting replication specificity determinants that have evolved independently in several geographical lineages. | a novel begomovirus isolated from a sida rhombifolia plant collected in sinaloa, mexico, was characterized. the genomic components of sida mosaic sinaloa virus (simsinv) shared highest sequence identity with dna-a and dna-b components of chino del tomate virus (cdtv), suggesting a vertical evolutionary relationship between these viruses. however, recombination analysis indicated that a short segment of simsinv dna-a encompassing the plus-strand replication origin and the 5´-proximal 43 codons of ... | 2014 | 24737005 |
| weedy hosts and prevalence of potential leafhopper vectors (hemiptera: cicadellidae) of a phytoplasma (16srix group) associated with huanglongbing symptoms in citrus groves. | huanglongbing (hlb) is a severe citrus (citrus spp.) disease associated with the bacteria genus candidatus liberibacter, detected in brazil in 2004. another bacterium was found in association with hlb symptoms and characterized as a phytoplasma belonging to the 16srix group. the objectives of this study were to identify potential leafhopper vectors of the hlb-associated phytoplasma and their host plants. leafhoppers were sampled every other week for 12 mo with sticky yellow cards placed at two h ... | 2012 | 22606800 |
| in vitro antibacterial activity and acute toxicity studies of aqueous-methanol extract of sida rhombifolia linn. (malvaceae). | many bacteria among the enterobacteria family are involved in infectious diseases and diarrhoea. most of these bacteria become resistant to the most commonly used synthetic drugs in cameroon. natural substances seem to be an alternative to this problem. thus the aim of this research was to investigate the in vitro antibacterial activity of the methanol and aqueous-methanol extracts of sida rhombifolia linn (malvaceae) against seven pathogenic bacteria involved in diarrhoea. acute toxicity of the ... | 2010 | 20663208 |
| sida rhombifolia ssp. retusa seed extract inhibits den induced murine hepatic preneoplasia and carbon tetrachloride hepatotoxicity. | sida rhombifolia ssp. retusa is a well established drug in the ayurvedic system of medicine used for antirheumatism and antiasthmatism. inhibitory effects of s. rhombifolia ssp. retusa seed extract on den induced hepatocellular preneoplastic foci and carbon tetrachloride (ccl4) induced hepatotoxicity was investigated in rats. rats received den, 1ppm/g b.w. in drinking water for 6 weeks or ccl(4), 0.7 ml/kg i.p. once a week for 4 weeks and seed extract 50 mg, 100 mg/kg b.w. orally prior, during a ... | 2009 | 20192593 |
| anti-arthritic activity of various extracts of sida rhombifolia aerial parts. | aerial parts of the plant sida rhombifolia linn. (malvaceae) were extracted successively to produce various extracts. these extracts were screened for various parameters of anti-arthritic activity, such as adjuvant-induced arthritis, motor performance, mean distance travelled, and histopathological study. results showed that the polar constituents (ethanol and aqueous extracts) of the plant s. rhombifolia were useful in the treatment of arthritis. | 2009 | 19418351 |
| evaluation of in vitro antioxidant activity of sida rhombifolia (l.) ssp. retusa (l.). | sida rhombifolia (l.) ssp. retusa (l.) is widely used in ayurvedic medicine for the treatment of fever as well as a diuretic. the comparative antioxidant potentials of ethanol extract of roots, stems, leaves, and whole plant were studied. estimation of total polyphenolic content and high-performance thin-layer chromatography profile were determined. further inhibition of oxygen-derived free radicals, viz., assays for free radical scavenging, reducing power, superoxide anion scavenging, nitric ox ... | 2007 | 18158841 |
| nucleotide sequence of a new bipartite geminivirus isolated from the common weed sida rhombifolia in costa rica. | the nucleotide sequence of infectious clones of a geminivirus from costa rica that infects sida rhombifolia was determined. sida golden mosaic virus (sigmv-co) has a bipartite genome (dnas a and b). computer analysis showed that the bipartite genome of sigmv-co resembles that of other whitefly-transmitted geminiviruses. the dna a (2605 nt) and dna b (2587 nt) components have little sequence homology other than within the common region (cr). analysis of dnas a and b showed that sigmv-co is closel ... | 1997 | 9225056 |
