An ethylene biosynthesis enzyme controls quantitative variation in maize ear length and kernel yield

Considerable genetic variation exists in maize ear size and kernel number. Here the authors show that variation in a gene encoding an ethylene biosynthetic enzyme impacts ear length, flower fertility and kernel yield suggesting an important role for ethylene signaling during inflorescence developmen...
