(Phys.org)—An international team of researchers has found evidence showing that maize evolved to survive in the U.S. southwest highlands thousands of years ago. In their paper published in the journal Science, the group ...
A new, much more detailed reference genome for maize, or corn, as it is called in the U.S., will be published in Nature today. In its accounting of the sequence of DNA letters in the plant's 10 chromosomes, the new version ...
