| molecular analysis of a full-length sequence of a new yam badnavirus from dioscorea sansibarensis. | badnavirus-like particles were observed by isem in viral preparations from yam (dioscorea sansibarensis) leaves from benin. use of the viral preparation as template for pcr amplification with badnavirus-specific primers gave rise to a 579-bp product with most nucleotide identity (70.8%) to dioscorea alata bacilliform virus (dabv, accession numbers x94575-x94582), the only other yam badnavirus sequenced to date. a full-length badnavirus sequence was generated, which consisted of 7261 nucleotides ... | 2007 | 17195956 |
| sequence diversity among badnavirus isolates infecting yam (dioscorea spp.) in ghana, togo, benin and nigeria. | we analysed the sequence diversity in the reverse transcriptase (rt)/ribonuclease h (rnaseh) coding region of 19 badnavirus isolates infecting yam (dioscorea spp.) in ghana, togo, benin, and nigeria. phylogenetic analysis of the deduced amino acid sequences revealed that the isolates are broadly divided into two distinct species, each clustering with dioscorea alata bacilliform virus (dabv) and dioscorea sansibarensis bacilliform virus (dsbv). fourteen isolates had 90-96% amino acid identity wit ... | 2008 | 19030955 |
| draft genome and description of orrella dioscoreae gen. nov. sp. nov., a new species of alcaligenaceae isolated from leaf acumens of dioscorea sansibarensis. | dioscorea sansibarensis is a monocot species of inedible yam native of tropical africa and madagascar. leaves of d. sansibarensis feature prominent acumen glands that are densely colonized by bacteria. we describe here the isolation and characterization of bacteria from leaf glands of d. sansibarensis specimens obtained from various botanical gardens. phylogenetic and phenotypic characterizations indicate that the isolates belong to a novel genus and species of the alcaligenaceae family for whic ... | 2017 | 27913074 |
| feasibility of bioethanol production from tubers of dioscorea sansibarensis and pyrenacantha kaurabassana. | inedible tubers from dioscorea sansibarensis (ds) and pyrenacantha kaurabassana (pk) were found to be suitable feedstock for bioethanol production. important composition parameters for bioethanol production for ds and pk are dry matter (% fresh tubers) ca. 20 and 6, total carbohydrates % dry weight base (db) ca. 68 and 47 and total protein (% db) ca. 16 and 10, respectively. ds and pk were found to contain inulin and galactomannan as principal polysaccharides (% of total carbohydrate) ca. 90 and ... | 2015 | 26298406 |
