Reversible nuclear genetic system for male sterility in transgenic plants |
摘要 |
Plant development can be altered by transforming a plant with a genetic construct that includes regulatory elements and DNA sequences capable of acting in a fashion to inhibit pollen formation or function, thus rendering the transformed plant reversibly male-sterile. In particular, the present invention relates to the use of dominant negative genes and an anther-specific promoter. Male sterility is reversed by incorporation into a plant of a second genetic construct which represses the dominant negative gene. The invention also relates to novel DNA sequences which exhibit the ability to serve as anther-specific promoters in plants.
