چکیده
"The Origin and Behavior of Mutable Loci in Maize," by Barbara McClintock, was published in 1950 in the Proceedings of the National Academy of Sciences [2] of the United States of America. McClintock worked at the Cold Spring Harbor Laboratory [3] in Laurel Hollow, New York, at the time of the publication, and in the article she describes her discovery of transposable elements in the genome [4] of corn (Zea mays [5]). Transposable elements, sometimes called transposons or jumping genes [6], are pieces of the chromosome capable of physically changing positions along the chromosome. "The Origin and Behavior" explains the mechanics of development that occur in maize kernels, which are plant embryos.

The origin of an unstable locus in maize.
I N maize many unst(ab1e gene loci can, upon analysis, be ascribed to specific mutable systems. Often these systems consist of two units: a controlling element, such as Ds or Z, which responds to a regulatory element, Ac or En, respectively (PETERSON 1965). In addition, in cultures known to contain elements of a mutable system, such1 as Ac-Ds (MCCLINTOCK 1950, 1951) or En-Z (PETERSON 1960, 1961...
متن کاملMcClintock's challenge in the 21st century.
In 1950, Barbara McClintock published a Classic PNAS article, "The origin and behavior of mutable loci in maize," which summarized the evidence leading to her discovery of transposition. The article described a number of genome alterations revealed through her studies of the Dissociation locus, the first mobile genetic element she identified. McClintock described the suite of nuclear events, in...

LMOST coincidental with the rediscovery of Mendelism, genes of high sponA taneous mutation rate, often referred to as unstable, labile or mutable genes, were found. Such mutable genes, although not described as such, were identified in association with variegated phenotypes especially noticeable in plants as flower color variegation. R. A.

متن کاملMUTABLE LOCI IN MAIZE t,
Previous reports have stated that a number of unstable loci have recently arisen in the maize cultures. In a particular cell of a plant, a normal “wild-type” locus becomes altered; the normal, dominant expression of this locus changes and gives rise to a recessive expression (or, in several cases, a recessive locus becomes unstable and mutates toward a dominant expression). This expression of t...
