The En/Spm transposable element has 13 exons. Eleven of the exons contribute to the 2.5-kb transcript (tnpA) that encodes the TNPA protein. The other two large exons contribute to a 6-kb transcript (tnpD) that encodes the TNPD protein. The TNPA protein conditions the genetically determined suppressor function (S) and the TNPD protein along with the TNPA(More)
Components of the Uq and Ac transposable element systems interact. A large sample of Ds-containing and ruq-containing alleles were tested against Uq and Ac. The Uq elements elicit a mutable response from only one of the classes of Ds elements (Ds1) in the Ac family. This response is similar to the response from ruq to Uq. In contrast, Ac elicits mutable(More)
From an original A2 allele (colored aleurone), a mutable allele, a2-m-4 1629, that changes from a2 to A2 is described. Mutability is expressed as a very distinct pattern limited to the last cell division.-The mutability of a2-m-4 1629 is autonomously controlled by an En at the a2 locus. This En, inactive on standard a testers for En, is partially active on(More)
