A 2-year field study has demonstrated that volatile compounds produced by plants when they are attacked by herbivores act as defenses by attracting predators to the herbivores and increasing the reproduction of the plants.

The use of tissue culture reduces the chemical modification of plant DNA, and this has lasting effects on gene expression in the plants and their descendants.

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.

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.

The ability of Manduca moths to recognize changes in the profile of volatile compounds released by plants being attacked by Manduca caterpillars allows them to lay their eggs on plants that are less likely to be attacked by insects and other predators, and to avoid competing against other caterpillars of the same species for resources.

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

The divergence of gene regulation during evolution in yeast traces phylogenetic distance with prominent changes being associated with changes in lifestyle and a whole genome duplication event.
