Copper deficiency in lucerne (Medicago sativa. L.)
In the course of these studies more questions have been posed than answered. It is clear that Lucerne production is being limited by low Cu levels in some areas. The relationships between yield and plant composition were rather different from those predicted from other studies; it is considered …

MOLECULAR ASPECTS OF DIRECT SOMATIC EMBRYOGENESIS IN ALFALFA (MEDICAGO)
… embryogenesis from differentiated leaf cells of Medicago falcata was used for this investigation. A RT-PCR strategy has been used for cloning two A-like cyclin genes termed cycMfl and cycMf2 and a cdc2 cDNA fragment from alfalfa. The full cDNA and genomic sequence of cycMfl was determined by the …

The control of embryogenic competence in Alfalfa (Medicago falcata L.)
Somatic embryogenesis is a process by which somatic cells undergo a developmental sequence similar to that observed in zygotic embryos. This process is not only an important plant propagation technique, but it also provides an essential tool for basic research into plant embryo development and …

CELL DIVISION AND EMBRYOGENIC COMPETENCE IN ALFALFA {Medicago falcata L.)
This investigation exploited a procedure for the production of somatic embryos directly from alfalfa leaf explants. Chopped leaf fragments were incubated in a liquid medium containing 2,4-D. The organisation of the swollen leaf tissue was disrupted and after 15 days the globular clusters of small …

Gene Expression Profiling of the nip Mutant in Medicago truncatula
… isolated a mutant called nip in the model legume Medicago truncatula that is defective in nodule symbiosis. The nip mutant (numerous infections with polyphenolics) becomes infected by Sinorhizobium meliloti but then accumulates polyphenolic defense compounds in the nodule and fails to progress to …

Variabilidad del ecotipo de alfalfa tierra de campos (Medicago sativa l.)
La comarca de Tierra de Campos es una extensa planicie de clima continental y suelos pesados. La principal especie forrajera que se cultiva es la alfalfa, que en secano es habitual que tenga un triple aprovechamiento: heno, pasto y semilla. Esta forma de manejo en este ambiente, a lo largo de los …

Map-based cloning of the NIP gene in model legume Medicago truncatula.
… reduces atmospheric nitrogen to ammonia. Medicago truncatula is the model legume plant that is used to study symbiosis with mycorrhiza and with the bacteria Sinorhizobium meliloti. The focus of this work is the M. truncatula nodulation mutant nip (numerous infections and polyphenolics). …

MtCEP1 peptides regulate lateral organ development in the model legume, Medicago truncatula
… MtCEP1, is studied in the model legume, Medicago truncatula, for its regulation of nitrogen-mediated root development, most particularly, lateral root and nodule formation. The MtCEP1 peptide-encoding gene is upregulated by low nitrogen condition, an environmental cue which strongly …

Regrowth analysis of alfalfa (Medicago sativa, L.) during three seasons in 1966
The rate of alfalfa regrowth during three seasons was associated with different parameters with the objective of finding a most suitable date of cutting in each season. The rate and total dry matter produced was higher during spring and early summer seasons than in late summer. The higher L.A.I. …

Phosphate homeostasis and posttranscriptional gene regulation during arbuscular mycorrhizal symbiosis in Medicago truncatula
Since available phosphate (Pi) resources in soil are limited, symbiotic interactions between plant roots and arbuscular mycorrhizal (AM) fungi are a widespread strategy to improve plant phosphate nutrition. The repression of AM symbiosis by a high plant Pi-status indicates a link between Pi …
