Scientists Develop GE Rice that Flower on Demand
April 6, 2017| |
University of Tokyo researchers genetically engineered rice that does not flower until it comes in contact with a specific fungicide. The results are published in Nature Plants.
Takeshi Izawa and colleagues developed non-flowering rice plants by overexpressing a floral repressor gene (Grain number, plant height and heading date 7) to block natural flowering. Then they co-transformed plants with a rice florigen gene (Heading date 3a), which is induced by particular agrochemicals. Plants that undergo a longer time of vegetative growth exhibited improved plant and panicle size as well as other yield-related characteristics.
The results of the study can lead to the development of crops that can grow in different climate types and facilitate breeding for different agronomical characteristics.
