| utilisation by sheep of herbage under tree crops in ghana. | a study conducted into the utilisation by sheep of herbage under a mango/cashew plantation at kade (ghana) showed the native herb, asystasia gangetica to be the most preferred herbage. centrosema pubescens was preferred to pueraria phaseoloides. the physical condition of the herbage affected their preference but the crude protein content did not have any influence. the mean daily digestible dry matter intake of yearling rams (g/kg w0.75) was 34, 31 and 39 for animals on brachiaria lata/pueraria ... | 1978 | 625790 |
| the effects of condensed tannins from desmodium intortum and calliandra calothyrsus on protein and carbohydrate digestion in sheep and goats. | a factorial experiment was conducted to study the effects of condensed tannins (ct) from the tropical legumes desmodium intortum and calliandra calothyrsus on the digestion and utilization of protein and carbohydrate in sheep and goats. ct-free centrosema pubescens was also fed for comparison with the ct legumes, and each legume was included (300 g/kg dm) in a basal diet of pangola grass (digitaria decumbens). pangola grass alone was used as a control diet. there were no significant (p > 0.05) d ... | 1996 | 8942360 |

| two new 'legumoviruses' (genus begomovirus) naturally infecting soybean in nigeria. | two new 'legumoviruses' (genus begomovirus; family geminiviridae) naturally infecting soybean (glycine max l. merr.) in nigeria were molecularly characterized. based on characteristic symptoms in soybean, the two viruses are provisionally designated as soybean mild mottle virus (sbmmv) and soybean chlorotic blotch virus (sbcbv). sbcbv has a bipartite genome, whereas sbmmv has only a dna a component. the dna a component of sbmmv is 2,768 nucleotides (nt) long and the dna a and dna b components of ... | 2010 | 20229118 |
| dual infection by cassava begomoviruses in two leguminous species (fabaceae) in yangambi, northeastern democratic republic of congo. | a study on cassava mosaic begomoviruses was conducted around yangambi (dr congo) by sampling 10 different leguminous species with or without symptoms similar to cassava mosaic disease. dna was isolated to amplify cmbs using primers targeting ac2 and ac4 genes for virus detection by pcr. the results showed a dual infection by acmv and eacmv in two weed species, centrosema pubescens and pueraria javanica, associated with mosaic symptoms. the dna-a genome component of acmv and eacmv from the infest ... | 2010 | 20680361 |
| g1 arrest and caspase-mediated apoptosis in hl-60 cells by dichloromethane extract of centrosema pubescens. | cell division and apoptosis are two crucial components of tumor biology and the importance of increased cell proliferation and reduced cell death have made them valid therapeutic targets. the plant kingdom is a relatively underexploited cache of novel drugs, and crude extracts of plants are known for their synergistic activity. the present study assessed the anti-proliferative activity of the medicinal plant centrosema pubescens benth. centrosema pubescens dichloromethane extract (cpde) inhibite ... | 2010 | 21061467 |
| fate of nitrogen-fixing bacteria in crude oil contaminated wetland ultisol. | the effect of crude oil on the growth of legumes (calopogonium muconoides and centrosema pubescens) and fate of nitrogen-fixing bacteria in wetland ultisol was investigated using standard cultural techniques. the results revealed observable effects of oil on soil physico-chemistry, plant growth and nodulation as well as on densities of heterotrophic, hydrocarbonoclastic and nitrogen fixing bacteria. the effects however varied with different levels (0.5%, 1%, 5%, 10%, 15% and 20%) of pollution. a ... | 2011 | 21755289 |
| genome sequence of bradyrhizobium viridifuturi strain semia 690t, a nitrogen-fixing symbiont of centrosema pubescens. | semia 690(t) is a nitrogen-fixing symbiont of centrosema pubescens, and comprises the recently described species bradyrhizobium viridifuturi. its draft genome indicates that it belongs to the bradyrhizobium elkanii superclade. semia 690(t) carries two copies of the regulatory nodd gene, and the nod and nif operons resemble those of bradyrhizobium diazoefficiens. | 2015 | 26679590 |
| bradyrhizobium viridifuturi sp. nov., encompassing nitrogen-fixing symbionts of legumes used for green manure and environmental services. | symbiotic nitrogen-fixing bacteria, commonly called rhizobia, are agronomically important because they can provide significant amounts of nitrogen to plants and help in recovery of impoverished soils and improvement of degraded environments. in recent years, with advances in molecular techniques, several studies have shown that these bacteria have high levels of genetic diversity, resulting in taxonomic reclassifications and descriptions of new species. however, despite the advances achieved, hi ... | 2015 | 26362781 |
| bioassay-guided isolation of active principles from nigerian medicinal plants identifies new trypanocides with low toxicity and no cross-resistance to diamidines and arsenicals. | leaves from the plant species studied herein are traditionally used in northern nigeria against various protozoan infections. however, none of these herbal preparations have been standardized, nor have their toxicity to mammalian cells been investigated. in search of improved and non-toxic active antiprotozoal principles that are not cross-resistant with current anti-parasitics, we here report the results of the in vitro screening of extracts from seven selected medicinal plant species (centrose ... | 2017 | 28336470 |
| milk production performance of friesian-holstein cows fed diets containing medicago sativa, centrosema pubescens, or groundnut haulms (arachis hypogaea). | to investigate the effect of feeding dairy cows diets containing lucerne hay, centrosema hay, and groundnut haulms (crop residue) on dry matter intake (dmi), milk yield, and milk composition, nine multiparous friesian-holstein cows in their mid-lactation stage were used in a 3 × 3 crossover design replicated three times. dairy cows fed lucerne hay had significantly (p < 0.001) higher dmi than dairy cows fed centrosema hay. dmi for cows fed groundnut haulms and lucerne hay was not significantly d ... | 2013 | 23460085 |
