We’re learning a lot more about the workhorse of the world’s flower beds and planter boxes: the Petunia Genome Project is complete, with the help of researchers from Northern Illinois University.

NIU professors Tom Sims and Rick Johns were among the primary researchers in the four year project. Johns says mapping the petunia’s DNA involved 50 researchers from 10 countries.

Science used to be one scientist working in a lab with a few students but now international collaboration is the rule, not the exception.

The Illinois Innovation Index report details research activity at Illinois' universities. The findings were issued this week by several groups, including the Chicagoland Chamber of Commerce and the Illinois Science & Technology Coalition.
