A chromosome 16 deletion conferring a high sucrose phenotype in soybean.

Sucrose in soybean seeds is desirable for many end-uses. Increased sucrose contents were discovered to associate with a chromosome 16 deletion resulting from fast neutron irradiation. Soybean is one of the most economically important crops in the United States.

Identification and characterization of a fast-neutron-induced mutant with elevated seed protein content in soybean.

Protein content of soybean is critical for utility of soybean meal. A fast-neutron-induced deletion on chromosome 12 was found to be associated with increased protein content. Soybean seed composition affects the utility of soybean, and improving seed composition is an essential breeding goal.

Systematic Mutagenesis of Serine Hydroxymethyltransferase Reveals an Essential Role in Nematode Resistance.

is a major genetic locus that contributes to soybean cyst nematode (SCN) resistance in the Peking-type resistance of soybean (), which also requires the gene. By map-based cloning and functional genomic approaches, we previously showed that the gene encodes a predicted cytosolic serine hydroxymethyltransferase (GmSHMT08); however, the novel gain of function of in SCN resistance remains to be characterized. Using a forward genetic screen, we identified an allelic series of mutants that shed new light on the mechanistic aspects of -mediated resistance.
