Long-term use of fallow in dryland wheat (Triticum aestivum L.) systems can increase erosion and decrease soil fertility. One possible solution is to grow a green manure crop during the fallow period. To evaluate the short-term effects of substituting a winter legume green manure for fallow in a 2-vr wheat rotation, a series of experiments were conducted in the Sacramento Valley of California f...

Rhizobial inoculants have been used successfully in world agriculture for about 100 years. About 20 million ha crop and pasture legumes are inoculated in the world each year, although that figure could be increased if high-quality inoculants were available to all farmers. The characteristics of a high-quality inoculant relate to the properties of the carrier, the infective (nodulating) and effe...

Reduced energy intake and weight loss on a legume-enriched diet lead to improvements in biomarkers related to chronic disease Hartman TJ, Zhang Z, Albert PS, et al Topics in Clinical Nutrition 2011; 26(3):208–15. The Legume Inflammation Feeding Experiment (LIFE) was designed to evaluate the effects of a highlegume, high-fiber, low-glycemic index diet on biomarkers of insulin resistance and infl...

Sheep and cattle farmers need pastoral systems that are more productive and environmentally sustainable. The role that high feeding value herb and legume forage species can play in the farms of the future is highlighted. It is shown that species such as chicory (Cichorium intybus), plantain (Plantago lanceolata), red clover (Trifolium pratense) and white clover (T.repens) can provide live weigh...

This study describes an outbreak of ulcerative posthitis that eventually affected 76 of 80 of rams in a flock of Rasa Aragonesa sheep on a legume-rich diet. Lesions were confined to the prepuce and varied from mild hyperaemia to ulcerations. Corynebacterium renale was isolated from the lesions. Treatment of an initial group of 17 was based on a change of diet and topical treatment with Veterin ...

Lectins are a diverse class of proteins distributed extensively in nature. Among these proteins; legume lectins display a variety of interesting features including antimicrobial; insecticidal and antitumor activities. Because lectins recognize and bind to specific glycoconjugates present on the surface of cells and intracellular structures; they can serve as potential target molecules for devel...

Griffonia simplicifolia 11, an N-acetylglucosamine-specific legume lectin, has insecticidal activity when fed to the cowpea weevil, Callosobruchus maculatus (F.). A cDNA clone encoding G. simplicifolia II was isolated from a leaf cDNA library, sequenced, and expressed in a bacterial expression system. The recombinant protein exhibited Kacetylglucosamine-binding and insecticidal activity against...

Legume cover crops are central to an ecological nutrient management approach that can reduce nitrogen (N) losses from agriculture. Diversifying cropping systems with a legume–grass crop mixture could further N by increasing soil assimilation and synchronizing mineralization uptake the following crop. We established four winter treatments (crimson clover, cereal rye, clover–rye mixture, weedy fa...

Legume specificity is encoded in rhizobial genetic elements that may be transferred among species and genera. Dissemination (by lateral transfer) of gene assemblies dictating host range accounts for the existence of the same biological variant (biovar) in distinct microbiological species. Different alternative biovars may exist in a single species expanding their adaptation to different niches ...
