Plants can be infected by multiple viruses at once. However, the composition of the pathogen community varies, even if individuals belong to the same species and the same population. Ecologists have now shown that these differences are primarily due to genetic variation among the hosts. The loss of genetic diversity could thus render species more vulnerable to infections and extinction.

The biological clock of a popular food crop controls close to three-quarters of its genes, according to a new research. The study can help researchers target genes to improve growth and stress resilience when a plant is moved to a new region or encounters changing climate conditions.

The dynamic change in root growth of plants plays an important role in their adjustment to soil conditions. Depending on the location, nutrients or moisture can be found in higher or lower soil layers. This is why, depending on the situation, a short or a long root is advantageous.

The enzyme Rubisco catalyzes the assimilation of CO2 from the atmosphere into organic matter. This is the central step in photosynthesis that generates sugar molecules for the production of essentially all biomass. Despite its pivotal role, Rubisco works relatively slowly and is easily inhibited by sugar products. By improving the function of Rubisco researchers hope to be able to boost the process of photosynthesis. The goal is to address the growing global demand for food and reduce the current greenhouse gas-induced climate change.
