Molecular analysis of the Ubiquitous (Uq) transposable element system of Zea mays.
The Uq transposable element of maize is the most widely dispersed among different maize populations and genetic testerstrains. Despite intensive genetic characterization, little is known about its molecular structure. In order to obtain information relevant to this topic, we have cloned and sequenced three ruq receptors. Surprisingly, they are all Ds1-like receptor types of the Ac-Ds transposon family. Based on our molecular data, we present a model to explain the functional differences associated with the differential expression of the Uq and Ac transposon systems.
