Analysis of a controlling-element mutation at the adh locus of maize.
A Ds-suppressed Adh mutant was isolated by the allyl alcohol pollen selection technique. The mutant produces a reduced level of an altered thermolabile enzyme suggesting that the Ds element is inserted in the Adh structural gene. The mutant protein is enzymatically active and does not differ detectably in size from the progenitor protein. A number of possible explanations for the data are prese...
متن کاملMutations at the shrunken-4 locus in maize that produce three altered phosphorylases.
ITH the recognition of enzyme systems that transfer the glucose moiety wfrom the nucleoside diphosphate sugars to glycogen or starch, some investigators have assumed that all synthesis of starch is mediated by such enzymes, and the role of phosphorylase is purely degradative (LELOIR 1964; WHELAN 1961 ) . On the other hand, BADENHUIZEN (1963) , PORTER (1962) and HASSID (1962) have maintained tha...
متن کاملControlling element-induced alterations in UDPglucose:flavonoid glucosyltransferase, the enzyme specified by the bronze locus in maize.
The bz locus in maize, which directs synthesis of the enzyme UDPglucose:flavonoid glucosyltransferase (UFGT) in the endosperm, is one of many loci at which controlling element-induced phenotypic changes are known. To characterize the nature of such modifications, several bz mutants derived by transposition of the controlling element Ds to the Bz gene were analyzed. Three mutants were found to l...
متن کاملIncreased gene expression by the first intron of maize shrunken-1 locus in grass species.
The first intron of the shrunken-1 (Sh1) locus of maize was incorporated into constructs containing the chloramphenicol acetyltransferase gene (CAT) coupled with the nopaline synthase 3' polyadenylation signal. Transcription was driven with the 35S promoter of the cauliflower mosaic virus (CaMV) or the Sh1 promoter of maize. Transient gene expression was monitored following electroporation into...
متن کاملMutation and paramutation at the R locus in maize.
HE R locus in maize exhibits two different kinds of genetic variability, mutation and paramutation (BRINK 1960). Mutation is a rare event, not predictable in an individual gamete, and produces a limited number of visually distinct mutant phenotypes. In contrast, paramutation is a directed change in the pigmenting ability of an R allele which invariably occurs in certain genotypes, and results i...
