January 2014, Annotation Release 101

This full annotation run includes the following assembly(ies):

Glycine max, is an annual herb of great economic importance. It belongs to family Fabaceae and tribe Phaseoleae which includes several other important legumes like beans, pigeon pea, black gram, mung bean etc. Cytogenetics showed that G. max is unique among the Phaseoleae. All others have a haploid chromosome number of 11. Current opinion has G. max derived from a diploid Phaseoleae ancestor (n = 11) that underwent an aneuploid loss to n = 10, followed by genome duplication. [(Lacky JA. Am J Bot 1980; 67: 595-602); (Palmer RG, Kilen TC. Qualitative Genetics and Cytogenetics. In: Wilcox JR, editor. Soybeans: Improvement, Production, and Uses. 2nd ed. Madison (WI): American Society of Agronomy, Inc., Crop Science Society of America, Inc., and Soil Science Society of America, Inc.; 1987 p. 135-209)]. Glycine max is believed to have originated in Asia but is now cultivated extensively for food and forage throughout the world. It is a major source of vegetable oil and protein in the world. Each soybean seed contains about 20% oil and about 50% of the remaining meal is protein.

G. max is considered to be a diploidized tetraploid with 2n = 40 chromosomes and a genome size of about 1115 Mb. Several well developed genomic resources are available: a well developed composite genetic map, large number of ESTs and a number of BAC libraries. The soybean genome sequence was deposited in NCBI in 2010 as WGS scaffolds and chromosome pseudomolecules. In 2011 the RefSeq chromosome accessions were prepared by NCBI.

The NCBI Map Viewer provides graphical displays of features on the genome assembly. Map features that can be seen along the sequence include annotated genes and transcripts, Gnomon-predicted gene and transcript models, aligned transcript and genomic sequences, RefSeq scaffolds (the 'Contig' map), the assembly tiling path (the 'Component' map), and more.

The genetic maps are built starting with the interspecific cross G. max x G. soja. Forty-six of 56 G. soja accessions from China and Russia exhibit chromosome interchanges relative to G. max, (Palmer RG, Newhouse KE, Garybosch RA, Delannnay X. J Hered 1987; 78: 243-247). The accession used in the mapping did not exhibit chromosome rearrangement. The map data is graciously provided by SoyBase.
