WebbThe ear of maize, though not easily interpreted, is not difficult to describe. It is a spike upon whose thickened axis (the cob) naked grains (caryopses) are borne in lon-gitudinal or somewhat spiral rows ; eight, ten, twelve or more in number. The number of rows is always even because the spikelets upon which the grains are borne are Webb4 maj 2015 · In this article, we have shown that an amino acid substitution in tga1 is the causal variant that underlies the origin of the naked grains of maize as compared to the covered grains of teosinte.
