Scientists
have unveiled
the genome of the soybean, saying it was an achievement that should
deepen understanding of one of the world’s most important crops, help
to boost yields and defend the plant against pests. Eighteen
organisations, most of them American, teamed up in a 15-year endeavour
that yielded a draft of 85 per cent of the soybean’s 1.1 billion base
pairs, the “rungs” in the double-helix ladder of DNA. More than 1,000
genes involved in lipid metabolism have been spotted, says researcher
Gary Stacey of the National Centre for Soybean Biotechnology at the
University of Missouri.
