Proteomic analysis reveals that auxin homeostasis influences the eighth internode length heterosis in maize (Zea mays)

Abstract Ear height is an important maize morphological trait that influences plant lodging resistance in the field, and is based on the number and length of internodes under the ear. To explore the effect of internodes on ear height, the internodes under the ear were analysed in four commercial hyb...
