Despite the 15 billion bushels grown in the United States last year alone, we still don’t know much about corn’s stem cells. To collect the samples, they carefully dissected tiny sections of maize and Arabidopsis plant shoots to harvest their stem cells. According to Jackson, the results form an open-source “atlas of gene expression” comprising around 5,000 CLAVATA3 and 1,000 WUSCHEL-expressing cells. “Other people interested in maize or Arabidopsis stem cells don’t have to repeat the experiment. Finally, the experts linked stem cell regulators responsible for maize productivity.
