an outbreak of primary photosensitisation in lambs secondary to consumption of biserrula pelecinus (biserrula). | an outbreak of photosensitisation affecting approximately 25% of a flock of 120 meat lambs that was grazing a monoculture of the pasture legume biserrula pelecinus var. casbah (biserrula) was investigated. blood samples were taken from sheep with moderate to severe clinical signs, and from apparently normal animals, for a complete blood count and biochemistry; 5 affected animals were subjected to a full necropsy. histopathological investigation showed lesions consistent with photosensitisation o ... | 2015 | 25939266 |
bioactive fractions from the pasture legume biserrula pelecinus l. have an anti-methanogenic effect against key rumen methanogens. | methanogenic archaea (methanogens) are common inhabitants of the mammalian intestinal tract. in ruminants, they are responsible for producing abundant amounts of methane during digestion of food, but selected bioactive plants and compounds may inhibit this activity. recently, we have identified that, biserrula pelecinus l. (biserrula) is one such plant and the current study investigated the specific anti-methanogenic activity of the plant. bioassay-guided extraction and fractionation, coupled wi ... | 2016 | 27060275 |
complete genome sequence of mesorhizobium opportunistum type strain wsm2075(t.). | mesorhizobium opportunistum strain wsm2075(t) was isolated in western australia in 2000 from root nodules of the pasture legume biserrula pelecinus that had been inoculated with m. ciceri bv. biserrulae wsm1271. wsm2075(t) is an aerobic, motile, gram negative, non-spore-forming rod that has gained the ability to nodulate b. pelecinus but is completely ineffective in n2 fixation with this host. this report reveals that the genome of m. opportunistum strain wsm2075(t) contains a chromosome of size ... | 2013 | 24976886 |
complete genome sequence of mesorhizobium ciceri bv. biserrulae type strain (wsm1271(t)). | mesorhizobium ciceri bv. biserrulae strain wsm1271(t) was isolated from root nodules of the pasture legume biserrula pelecinus growing in the mediterranean basin. previous studies have shown this aerobic, motile, gram negative, non-spore-forming rod preferably nodulates b. pelecinus - a legume with many beneficial agronomic attributes for sustainable agriculture in australia. we describe the genome of mesorhizobium ciceri bv. biserrulae strain wsm1271(t) consisting of a 6,264,489 bp chromosome a ... | 2014 | 25197432 |
complete genome sequence of mesorhizobium australicum type strain (wsm2073(t)). | mesorhizobium australicum strain wsm2073(t) was isolated from root nodules on the pasture legume biserrula pelecinus growing in australia in 2000. this aerobic, motile, gram negative, non-spore-forming rod is poorly effective in n2 fixation on b. pelecinus and has gained the ability to nodulate b. pelecinus following in situ lateral transfer of a symbiosis island from the original inoculant strain for this legume, mesorhizobium ciceri bv. biserrulae wsm1271. we describe that the genome size of m ... | 2013 | 24976896 |
complete genome sequence of mesorhizobium ciceri bv. biserrulae strain wsm1284, an efficient nitrogen-fixing microsymbiont of the pasture legume biserrula pelecinus. | we report the complete genome sequence of mesorhizobium ciceri bv. biserrulae strain wsm1284, a nitrogen-fixing microsymbiont of the pasture legume biserrula pelecinus the genome consists of 6.88 mb distributed between a single chromosome (6.33 mb) and a single plasmid (0.55 mb). | 2016 | 27284134 |
mesorhizobium australicum sp. nov. and mesorhizobium opportunistum sp. nov., isolated from biserrula pelecinus l. in australia. | biserrula pelecinus l. is a pasture legume that was introduced to australia from the mediterranean basin in 1993. although the native rhizobial population could not nodulate b. pelecinus at the time of its introduction, recent research has shown the emergence of a diversity of strains (novel isolates) that are able to do so. three novel isolates, wsm2073t, wsm2074 and wsm2076, had nearly identical 16s rrna gene sequences, and clustered separately with all recognized species of the genus mesorhiz ... | 2009 | 19605705 |
in situ lateral transfer of symbiosis islands results in rapid evolution of diverse competitive strains of mesorhizobia suboptimal in symbiotic nitrogen fixation on the pasture legume biserrula pelecinus l. | the multi-billion dollar asset attributed to symbiotic nitrogen fixation is often threatened by the nodulation of legumes by rhizobia that are ineffective or poorly effective in n(2) fixation. this study investigated the development of rhizobial diversity for the pasture legume biserrula pelecinus l., 6 years after its introduction, and inoculation with mesorhizobium ciceri bv. biserrulae strain wsm1271, to western australia. molecular fingerprinting of 88 nodule isolates indicated seven were di ... | 2007 | 17803775 |
mesorhizobium ciceri biovar biserrulae, a novel biovar nodulating the pasture legume biserrula pelecinus l. | biserrula pelecinus l. is a pasture legume species that forms a highly specific nitrogen-fixing symbiotic interaction with a group of bacteria that belong to mesorhizobium. these mesorhizobia have >98.8 % sequence similarity to mesorhizobium ciceri and mesorhizobium loti for the 16s rrna gene (1440 bp) and >99.3 % sequence similarity to m. ciceri for the dnak gene (300 bp), and strain wsm1271 has 100 % sequence similarity to m. ciceri for gsii (600 bp). strain wsm1271 had 85 % relatedness to m. ... | 2007 | 17473255 |
rapid in situ evolution of nodulating strains for biserrula pelecinus l. through lateral transfer of a symbiosis island from the original mesorhizobial inoculant. | diverse rhizobia able to nodulate biserrula pelecinus evolved following in situ transfer of noda and nifh from an inoculant to soil bacteria. transfer of these chromosomal genes and the presence of an identical integrase gene adjacent to a phe trna gene in both the inoculant and recipients indicate that there was lateral transfer of a symbiosis island. | 2006 | 16936054 |
phylogenetic relationships of three bacterial strains isolated from the pasture legume biserrula pelecinus l. | three bacterial strains (wsm 1283, wsm 1284, wsm 1497) isolated from root nodules of the pasture legume biserrula pelecinus l. growing in morocco, italy and greece, respectively, were studied in order to determine their phylogenetic relationship to the other members of the family rhizobiaceae. a polyphasic approach, which included analyses of morphological and physiological characteristics, plasmid profiles, symbiotic performance and 16s rrna gene sequencing, indicated that these strains belong ... | 2001 | 11760938 |
