Doctoral thesis on the future of wheat

Lorena Guardia Velarde will defend her doctoral thesis on how plant breeding can improve wheat yields while reducing fertilizer use, focusing on the genetics behind nitrogen efficiency in spring wheat.

Different wavelengths of light can improve plant protection

Plant surfaces are not always a hospitable environment for beneficial bacteria that help protect plants from pests. However, in a new doctoral thesis, Maria Hellström has investigated how different wavelengths of light can support these bacteria, both in lab and greenhouse environments.

New model provides better insights into the lobster stock

The lobster stock in Sweden is at biologically sustainable levels, although there is still some risk of overfishing. This is the conclusion of the latest stock assessment, developed using an improved modeling tool that accounts for more uncertainty factors.

High-yielding rice that greatly reduces methane emissions has been developed at SLU

Rice is a staple food for half the world's population, but its cultivation leads to significant emissions of the greenhouse gas methane. Now, researchers from SLU and colleagues in China have identified two chemical compounds secreted from rice roots that affect the amount of methane emissions. This knowledge made it possible to breed a high-yielding variety of rice that reduces methane emissions by up to 70 per cent.
