Review of factors determining legumes sod-seeding outcome during pasture renovation in North America
Pasture renovation entails introduction of desirable forage species, usually legumes such as red clover (Trifolium pratense L.), white clover (Trifolium repens L.) or birdsfoot trefoil (Lotus corniculatus L.), into a grass dominated pasture. A commonly used method of pasture renovation consists in drilling seeds into the grass sod (sod-seeding). Introduced legumes benefit the pasture in three w...
________________________________________________________________________________ Abstract The effect of the feeding schedule and the use of additives on the intake and its rate were studied on animals consuming a temperate pasture. Twenty four wethers (47.8 ± 6.4 kg BW), housed in metabolism cages, were fed a fresh pasture (80% Lotus corniculatus) and assigned to four groups. Group AD had forag...
Evolutionary theory suggests that divergent natural selection in heterogeneous environments can result in locally adapted plant genotypes. To understand local adaptation it is important to study the ecological factors responsible for divergent selection. At a continental scale, variation in climate can be important while at a local scale soil properties could also play a role. We designed an ex...
The gln-gamma gene, which specifies the gamma subunit of glutamine synthetase in Phaseolus vulgaris L., has been isolated and the regulatory properties of its promoter region analyzed in transgenic Lotus corniculatus plants. A 2-kilobase fragment from the 5'-flanking region of gln-gamma conferred a strongly nodule-enhanced pattern of expression on the beta-glucuronidase reporter gene. Parallel ...
Ensifer arboris LMG 14919(T) is an aerobic, motile, Gram-negative, non-spore-forming rod that can exist as a soil saprophyte or as a legume microsymbiont of several species of legume trees. LMG 14919(T) was isolated in 1987 from a nodule recovered from the roots of the tree Prosopis chilensis growing in Kosti, Sudan. LMG 14919(T) is highly effective at fixing nitrogen with P. chilensis (Chilean...
The two temperate forage legumes containing condensed tannins (CT) that promote ruminant production are birdsfoot trefoil (Lotus corniculatus L.; BFT) and sainfoin (Onobrychis viciifolia Scop.; SF). Both are well-adapted to the cool-temperate climate and alkaline soils of the Mountain West USA. Condensed tannins comprise a diverse family of bioactive chemicals with multiple beneficial functions...
BACKGROUND Fusarium oxysporum has worldwide distribution and causes severe vascular wilt or root rot in many plants. Strains are classified into formae speciales based on their high degree of host specificity, of which multilocus sequence typing provides a fairly good estimate. AIMS The main aim of this study was to identify the causal agent of an infected potato tuber in Colombia. METHODS ...
