Tobacco's genetic makeup which includes between 25 and 50 thousand genes. It is being researched now at North Carolina State University (thanks in large part to a grant from Philip Morris). They hope to have it mapped by 2007. Since tobacco is related to peppers, potatoes, and tomatoes (that's the family Solanaceae, if you're keeping score at home), so this is seen as an important foundational effort in mapping the vegetable kingdom. And it is hoped that it will help efforts to breed out some of the harmful effects of tobacco products.
