Structural and biochemical analysis of a protein called Ecp6, which is produced by a tomato fungus, reveals how the protein prevents plants from launching an immune response to the chitin in fungal cell walls.

Plants implement arithmetic division to optimize use of carbohydrate reserves and thus maintain metabolism and growth at night.

The plant hormone ethylene regulates the expression of multiple genes in the model plant Arabidopsis, including those that respond to other hormones.

The circadian clock in the model plant organism Arabidopsis thaliana is best described as a highly connected network made up of clock-regulated activators and repressors of transcription, rather than two coupled, repressor-based feedback loops.

Sugar levels in leaves act as a signal for plants to switch from their juvenile to their adult form by regulating the expression of two genes.
