Medicago truncatula proteomics
Journal of Proteomics, 2010Legumes (Fabaceae) are unique in their ability to enter into an elaborate symbiosis with nitrogen-fixing rhizobial bacteria. Rhizobia-legume (RL) symbiosis represents one of the most productive nitrogen-fixing systems and effectively renders the host plants to be more or less independent of other nitrogen sources.

Comparative studies on tolerance of Medicago truncatula and Medicago falcata to freezing
Planta, 2011Medicago falcata is a legume species that exhibits great capacity of tolerance to abiotic stresses. To elucidate the mechanism underlying tolerance of M. falcata to freezing, we compared the characteristics of M. falcata in response to cold acclimation and freezing with those of the legume model plant Medicago truncatula. M. falcata seedlings were more

Somatic Hybrization of Medicago Sativa and Medicago Falcata
1983The aim of our work was to study somatic hybridization in the genus Medicago. Indeed we would like to increase variability in cultivated lucerne, M. sativa, by introducing characters of wild species. Since interspecific hybridizations are very difficult because of differences in ploidy levels we think that somatic hybridization is a way to overpass ...

The following chronological account of geological and climatological developments during the Tertiary Period according to Durham (1975), Hsu (1973, 1978) and Hsu et al. (1973, 1977) may provide a general background for understanding what might have influenced Medicago evolution, and may be of use as a reference to other non-geologists, like ourselves.

Electric Field Mediated Fusion of Protoplasts of Medicago sativa L. and Medicago arborea L.
Journal of Plant Physiology, 1988Summary Electroffusion was performed with root and cell suspension protoplasts of Medicago sativa L. and mesophyll protoplasts of Medicago arborea L. In order to obtain the highest yield of binary fusion products, two factorial experiments were carried out to establish the optimal values of protoplast density, AC field strength, number, duration,

Medicago sativa and Medicago murex differ in the nodulation response to soil acidity
Plant and Soil, 2002Nodulation of Medicago sativa by Sinorhizobium meliloti is challenged by acidity, but the ability of M. murex to nodulate in acid soils provided the opportunity to compare the symbiotic development between the two species in an acid sandy soil. Soil acidity had different effects on the nodulation of Medicago spp. In soil of pH 4.3, M.
