Wheat grain, which contains high levels of starch and protein located in the endosperm, is being developed as a 揵ioreactor?using the new gene transfor-mation technology1]. Some new traits (such as virus and insect resistance) have been successfully introduced into key cereal crops using transgene technology, however, there are only a few reports on the studies of transgene expression in wheat because of technical difficulties…
