Abstract:
Numerous studies show that plastid DNA is inherited biparentally in alfalfa (Medicago sativa L.). Mitochondrial DNA has been shown to be inherited in a uniparental-maternal fashion in a limited number of sexual crosses. This study investigated the inheritance of mitochondrial DNA in 54 alfalfa progenies from crosses between two cytoplasmic male sterile maternal plants and 54 paternal plants, representing each of the eight basic germplasm groups of M. sativa. Cloned mitochondrial DNA fragments from M. sativa were used as hybridization probes to identify polymorphisms in mitochondrial DNA for Ec

Abstract:
The synthesis of isoflavonoid phytoalexins in legumes is relatively well understood, but far less is known about how these phytotoxic compounds are metabolised by the plant when no longer required. In this project medicarpin, the major isoflavonoid phytoalexin in alfalfa, was prepared in radiolabelled form and fed to cell cultures and seedlings of alfalfa. The metabolism of the radioactive phytoalexin was then studied by characterising the radiolabelled metabolites formed. Uptake of radiolabelled phytoalexin by cells was faster in elicitor-treated cultures than in untreated cultures. However,

Resulting F1 hybrids were triploid (2n = 3x = 24), completely male sterile and had low levels of female fertility. Subsequent populations were obtained by successive backcrossing to unrelated (4x) M. sativa clones. The BC1 plants were pentaploid (2n = 5x = 40) and both male and female fe

Abstract:
The seed germination process during sprout production provides suitable environmental conditions for the growth of pathogenic bacteria, such as Listeria monocytogenes. A potential way to control this bacterial growth is through the use of bacteriophages, which are naturally occurring viruses that specifically attack bacterial targets and have been shown to be effective antimicrobials in some foods. Therefore, the objective of this study was to evaluate the antimicrobial susceptibility of L. monocytogenes to bacteriophage on alfalfa sprouts during seed germination and subsequent refrigerated st

Chez les legumineuses, les flavonoides ont une double fonction de composes antimicrobiens (phytoalexines) et d'inducteurs de la transcription des genes nod des bacteries symbiotiques de type rhizobium. L'expression chez la luzerne des genes chalcone synthase (chs), chalcone reductase (chr), chalcone isomerase (chi) et isoflavone reductase (ifr), impliques dans la biosynthese de la phytoalexine medicarpine, a ete etudiee lors de reactions de defense et de symbiose. Plusieurs adnc codant pour la chr ont ete isoles et leur expression caracterisee comparativement a celle de la chs. L'infection des

Abstract:
Le genre Medicago appartient à la famille des Légumineuses; il comprend plus de 50 espèces largement réparties dans le monde. Une faible part de richesse génétique est exploitée. En effet l’espèce M. Sativa et dans une moindre mesure l’espèce M. Falcata constituent la base génétique de l’espèce cultivée. La sélection classique a donné beaucoup de résultats mais actuellement certains problèmes tels l’amélioration du rendement sont difficiles à résoudre. C’est pourquoi un travail sur l’augmentation de la variabilité génétique au sein de l’espèce cultivée a été entrepris. L’objectif était l’explo

Abstract:
The use of coated seed to establish crops is not a novel practice. Seed coatings have been used on small seeded crops to improve the handling ability by making the seed unit larger and heavier. Producers can therefore calibrate their sowing equipment more efficiently and wind will not cause as much drift at sowing. Seed coating can have an added benefit for leguminous crops if the symbiotic inoculant (Rhizobium) is added to the coating. This saves the producer time and allows peace of mind that inoculation was done by trained professionals. Other than the inoculation, there are some other con
