EVIDENCE FOR GENE INACTIVATION IN THE VIRUS-INDUCED ABERRANT RATIO PHENOMENON IN MAIZE

[摘要] Reciprocal crosses were made between pairs of plants showing the "aberrant ratio" (AR) effect at the a locus, and simultaneously between these plants and an aa tester. The results suggested that the AR effect in the particular line that was used could be explained by inactivation of a gene other than A , but also required for aleurone color. Segregation ratios in additional crosses largely fit expectations predicted on the basis of this hypothesis.
