The Medicago Genome Provides Insight into the Evolution of Rhizobial Symbioses
TLDR
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. Expand
Mining EST databases to resolve evolutionary events in major crop species.
TLDR
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. Expand
Gene Trees and Species Trees: Molecular Systematics as One-Character Taxonomy
TLDR
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. Expand
Estimating genome conservation between crop and model legume species.
TLDR
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. Expand
The Rest of the Iceberg. Legume Diversity and Evolution in a Phylogenetic Context1
TLDR
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. Expand
DNA Protocols for Plants
TLDR
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. Expand
Phylogeny, biogeography, and processes of molecular differentiation in Quercus subgenus Quercus (Fagaceae).
TLDR
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. Expand
