Segregation of Color and Growth-Regulating Genes in Somatic Tissue of Maize

Abstract

A microscopical examination of mature seeds of Zea mays in a number of different lines has shown a surprisingly large number of color and growth mosaics in aleurone and endosperm tissue. Maize endosperm is unusually favorable material in which to study genetic changes in somatic tissue. It is a short-lived, food-storage structure. Changes can occur late in development with no serious injury to the young seedling. Consequently aberrations have not been selected against as severely as in other parts of the organism.
