Journal Club: Genetic detective work suggests a crucial role for Maya in papaya domestication

Posted on March 25, 2015 by Charles Choi

Papaya is a multimillion-dollar crop with a complicated sex life. Now plant geneticist Ray Ming at the University of Illinois at Urbana-Champaign and his colleagues find that hermaphrodite papayas, the version most useful to farmers, most likely arose due to … Continue reading →
