Abstract: | Summary Poly(A)4 RNA was isolated from maize scutella of different stages of post-germinative development and translated in vitro in a rabbit reticulocyte translation system. Immunoprecipitation of the translation products with CAT-2-specific antibody was used to quantitate the relative levels of translatable CAT-2 mRNA at each stage. The results show a close correlation between the developmental profile of Cat2 gene expression and the profile of CAT-2 mRNA levels. Evidence that the levels of CAT-2 mRNA are regulated by a temporal regulatory gene (Car1) is presented and the possible mechanism(s) of this regulation discussed.This work was supported by Research Grants No. GM22733 and No. GM33817 from the U.S. National Institutes of Health, Public Health Service to J.G.S.
