The draft sequence of the M. truncatula genome sequence is described, a close relative of alfalfa (Medicago sativa), a widely cultivated crop with limited genomics tools and complex autotetraploid genetics, which provides significant opportunities to expand al falfa’s genomic toolbox.

Pearson's correlation coefficients were calculated to provide a measure of how gene expression patterns have changed between duplicate pairs, and showed that some duplicates seemed to retain expression patterns between pairs, whereas others showed uncorrelated expression.
Gene Trees and Species Trees: Molecular Systematics as One-Character Taxonomy

A character phylogeny, in this case a gene tree, can be tested best by a parsimony analysis in which other characters are included, and each is an equivalent phylogenetic hypothesis, as is each non-molecular character, leading to the suggestion that direct combination is appropriate.

Comparisons of sequenced regions of the model legume Medicago truncatula with those of the diploid Lotus japonicus and the polyploid Glycine max suggest that comparative mapping may have considerable utility for basic and applied research in the legumes, although its predictive value is likely to be tempered by phylogenetic distance and genome duplication.
The Rest of the Iceberg. Legume Diversity and Evolution in a Phylogenetic Context1
Most readers of a special issue of Plant Physiology on legumes will be familiar with only a handful of species, primarily pea and the various economically important “beans” such as soybean, and the model legumes Medicago truncatula and Lotus japonicus.
DNA Protocols for Plants

The method is used to isolate total genomic DNA (nuclear, chloroplast, and mitochondrial) and is a rapid, inexpensive method that is suitabie for use in conjunction with other protocois, such as isolation of DNA enriched for cpDNA.
Phylogeny, biogeography, and processes of molecular differentiation in Quercus subgenus Quercus (Fagaceae).
The biogeographic hypothesis that all major oak lineages evolved locally at middle latitudes within the general distribution of their fossil ancestors was fully supported and a New World origin for the widespread white oaks of the Northern Hemisphere was suggested.
