Plant Cell Engineering Lab
Machine-translated · View original
A lab that studies how plants reproduce and creates new plants through genetic modification.
AboutAbout the lab
Understanding the basics leads to applications.
The Plant Cell Engineering Lab studies the mechanisms of sexual reproduction in plants and the development of new plants through genetic modification.
In particular, it investigates how double fertilization in angiosperms is regulated, using microscopy and molecular biology methods.
Work centers on experiments inside the lab, and depending on the research theme it may also include fieldwork.
The lab welcomes people from science faculties as well as from horticulture and agriculture faculties.
Key terms
- Double fertilization
- A mechanism unique to angiosperms in which two sperm cells from pollen fertilize the egg cell and the central cell, one each
- Agrobacterium
- A soil bacterium that naturally transfers its own genes into plants. It is used as a tool for introducing genes into plants
- Cross-incompatibility
- The failure to produce offspring when plants of different kinds are crossed, because fertilization or seed development does not proceed properly
ResearchResearch themes
The lab pursues basic research that clarifies how plants reproduce, and research that develops new plants through genetic modification. It aims to connect knowledge of the basics to applications in plant breeding.
*Illustrative imageCreating New Plants through Genetic Modification
The lab develops methods to regenerate whole plants from plant cells and methods to introduce genes, adapted to each plant species and tissue. Mainly using a bacterium called Agrobacterium, it introduces useful genes into cells to produce genetically modified plants with traits such as disease resistance or altered flower color.
*Illustrative imageUnderstanding How Plants Reproduce
Depending on the combination of plants, crossing may fail and no offspring can be obtained. To lead to techniques that overcome such cross-incompatibility, the lab searches for factors that control the reproductive process in angiosperms and studies how they function.
MembersFaculty
