Example Sentences:
(1) All of the Ac insertions affect both pericarp and cob glume pigmentation, providing further evidence that the P-rr allele contains a single gene required for both pericarp and cob glume pigmentation.
(2) flower glume colour, degree of lateral spikelets development, hairy rechis of the ear, were observed in diallel crosses among the varieties Nutans 244, Trumpf, DZ-02389, Hiproly and Brachitic.
(3) The P-rr allele of the maize P gene regulates the synthesis of pigments derived from flavan-4-ol in the pericarp, cob glumes and other floral organs.
(4) Four general conclusions are made: (1) anthers are initiated from small groups of 12 or fewer cells in each of two floral meristematic layers; (2) the early growth of the anther is more like a shoot than a glume or leaf; (3) cell ancestry does not dictate basic structure and (4) the orientation of initial cells predicts the orientation of the four pollen-containing microsporangia, which define the axes of symmetry on the mature anther.
