University
of Birmingham scientists took a plant called Arabidopsis Thaliana which is a
self-fertile plant and made it reject its own pollen by inserting two genes
found in a field poppy called “Papaver rhoeas.” The poppy creates two proteins,
PrpS and PrsS which identifies the plant. When a plants flowers receives its
own pollen, it recognizes it is from itself, the pollen begins its programmed
cell death, and stops itself from germinating. Research shows that when just
these two genes alone were transferred into the Arabidopsis Thaliana, it was
enough for it to become self-incompatible. In the future, scientists hope to be
able to implement this into more crops and breed hybrid plants which give off
better yields and strength. They also plan to make F1 hybrids easier as this
would make it cheaper and easier for plant breeders to create superior plants
and seeds.
This research
in this article is particularly interesting because the poppy plant isn’t even
closely related to the Arabidopsis plant. It also amazes me how plants can not
only reject itself, but can reject close relatives of itself as well. It is
fascinating how two different breeds of plant can use the same genes to make
the plants work in the same way. If this works and can become implemented into
more plants, food quality will soar as well as hopefully be cheaper which can
create a big impact on the world.
