Yield-boosting stay-green gene identified from 118-year-old experiment in corn

A corn gene identified from a 118-year-old experiment could boost yields of today’s elite hybrids with no added inputs. The gene controls a critical piece of senescence, or seasonal die-back, in corn. When the gene is turned off, field-grown elite hybrids yielded 4.6 bushels more per acre on average than standard plants.
