How plants react to fungi

Plants are under constant pressure from fungi and other microorganisms. The air is full of fungal spores, which attach themselves to plant leaves and germinate, especially in warm and humid weather. Some fungi remain on the ...

How plants measure their carbon dioxide uptake

When water is scarce, plants can close their pores to prevent losing too much water. This allows them to survive even longer periods of drought, but with the majority of pores closed, carbon dioxide uptake is also limited, ...

News about a plant hormone

Jasmonic acid gives the plant Jasminum grandiflorum its characteristic odor and is used in the cosmetics and perfume industries. Plants wounded by things like chewing herbivores produce jasmonic acid as a defense signal, ...

Why cereal crops are better

Cereal crops are much more drought-tolerant than other plants. Researchers from Würzburg have now found out why that is so. Their insight could help breed crops that are more resistant to drought.

An amino acid controls plants' breath

Plants breathe and "sweat" through stomata, microscopic pores found on leaves, stems and other plant organs. Through the stomata, plants take up carbon dioxide for photosynthesis and breathe out the products of this process, ...

Genome evolution and carbon dioxide dynamics

Using the size of guard cells in fossil plants to predict how much DNA each cell contained (the genome size), researchers have discovered that variations in genome sizes over geological time correlate with atmospheric carbon ...
