Abstract Detail



Symposium: Speaking of Food: connecting basic and applied science

Doyle, Jeff [1].

The wild side of a major crop: Soybean's perennial cousins from Down Under.

Soybean(Glycine max) is one of the world's major crop plants, and many botanists are aware that it originated in Asia from a native wild annual species, G. soja. Far fewer people know that all other Glycine species are perennials, native to Australia. These species harbor many traits of interest to soybean breeders, among them resistance to major soybean pathogens such as cyst nematode and leaf rust. It may also come as a surprise to learn that new species in the Australian subgenus continue to be described,due both to the collection of new material and to systematic studies of existing samples in germplasm collections. From taxonomy to 'omics research,perennial Glycine are targets of a number of ongoing studies. They also serve as models for studying polyploidy,from the ancestral events that shaped the genome of their common ancestor with soybean, to more recent allopolyploidy that may be associated with the arrival of humans in Australia. In addition, other studies involve detailed sequence characterization of orthologous genomic regions known from soybean to include genes for key resistances as well as physiological and developmental traits related to soybean breeding.
