The Legume Information System (LIS; https://legumeinfo.org) houses genetic and genomic data, integrated in various online tools to allow comparative analyses. website database maintain data for more than two dozen species, particularly focusing on crop model species holding other diverse of taxonomic interest. Major analysis features include genome browsers, sequence-search tools, legume-focuse...

Weed management is essential for sustainable crop production in all cropping systems. The use of herbicides causing the problems herbicide resistant weeds and environmental pollution. Plant-released phytotoxins have ability to promote or inhibit germination seedling growth surrounding crops weeds. Therefore, it imperative identify plant species having herbicidal potential as more safe weed appr...

Ensifer (Sinorhizobium) medicae is an effective nitrogen fixing microsymbiont of a diverse range of annual Medicago (medic) species. Strain WSM419 is an aerobic, motile, non-spore forming, Gram-negative rod isolated from a M. murex root nodule collected in Sardinia, Italy in 1981. WSM419 was manufactured commercially in Australia as an inoculant for annual medics during 1985 to 1993 due to its ...

Because flavonoids from legumes induce transcription of nodulation genes in symbiotic rhizobial bacteria, it is reasonable to test whether these compounds alter the development of vesicular-arbuscular mycorrhizal (VAM) fungi that infect those plants. Quercetin-3-O-galactoside, the dominant flavonoid released naturally from alfalfa (Medicago sativa L.) seeds, promoted spore germination of Glomus...

A diversity of forage species and forage ecosystems suited to different management practices exists in the United States. The future of cultivar development in forages includes the new and evolving areas of genomic and transgenic technologies. Genomic research gained momentum with the publication of the complete DNA sequence of the human genome and has since expanded to plant species including ...

Five alfalfa (Medicago sativa L) cultivars from different areas of Iran were evaluated for oxidative markers under salinity conditions. Plants were grown in hydroponic condition by Hoagland nutrient solution containing different amounts of NaCl (control, 50 and 100 mM). Relative growth rate, membrane stability, lipid peroxidation, proline, hydrogen peroxide and relative water contents were dete...

Under nitrogen-limiting conditions Rhizobium meliloti can establish symbiosis with Medicago plants to form nitrogen-fixing root nodules. Nodule organogenesis starts with the dedifferentiation and division of root cortical cells. In these cells the early nodulin gene enod40, which encodes an unusually small peptide (12 or 13 amino acids), is induced from the beginning of this process. Herein we ...
