CONTROL OF MICROSPOROGENESIS BY EXTERNALLY INDUCIBLE PROMOTER SEQUENCES |
| 摘要 |
An inducible promoter is used to regulate expression of a gene which is known to be critical in microsporogenesis, i.e., the production of pollen. The selected gene's control sequences are modified so that it is normally "off" and as a result the plants are male sterile. When it is desired to reproduce the male sterile plants, male fertility is restored by treating the plants with a non-phytotoxic chemical which induces expression of the critical gene.
