Maize bronze 1:dSpm insertion mutations that are not fully suppressed by an active Spm.
The Suppressor-mutator (Spm) family of maize transposable elements consists of autonomous Spm elements and nonautonomous defective Spm (dSpm) elements. One characteristic of this family is that the insertion of dSpm elements into a structural gene often permits some level of structural gene expression in the absence of SpM activity, and this structural gene expression is suppressed in trans by ...
متن کاملCharacterization of an spm-controlled bronze-mutable allele in maize.
The association of a receptor (Rs) of the Spm system with a Bz-1 allele has created a two-element Spm-controlled bz-mutable allele (bz-m13) of maize (Zea mays L.). In the absence of Spm, one copy of bz-m13 (bz/bz/bz-m13 ) conditions full anthocyanin production in the aleurone layer of the seed. In the presence of this Spm, bz-m13 produces a unique, coarsely variegated seed phenotype and has a h...
متن کاملC. elegans unc-105 mutations affect muscle and are suppressed by other mutations that affect muscle.
Certain mutations in the unc-105 II gene of the nematode Caenorhabditis elegans have dominant effects on morphology and behavior: animals become small, severely hypercontracted and paralyzed. These unc-105 mutants revert both spontaneously and with mutagens at high frequencies to a wild-type phenotype. Most of the reversion events are intragenic, apparently because the null (loss-of-function) p...
متن کاملHeterogeneous flavonoid glucosyltransferases in purple derivatives from a controlling element-suppressed bronze mutant in maize.
The Ds(Dissociation)-suppressed bronze mutant bz-m2(DI), which is extremely stable in the absence of the regulatory element Ac (Activator), becomes both somatically and germinally unstable when Ac is present. Instability in the germ line may result in the generation of stable (Ac-nonresponding), colored Bz' derivatives. The characterization of several properties of the Bz-controlled enzyme UDPg...
