Auxin is the main phytohormone controlling root development in plants. Correa-Aragunde et al. grow seedlings of Arabidopsis thaliana treated with auxin with or without thioredoxin

Litter often decomposes faster in its environment of origin (at ‘home’) than in a foreign environment (‘away’), which has become known as the home-field advantage

Reactive oxygen species (ROS) are considered to be detrimental to seed viability. However, recent studies have demonstrated that ROS have key roles in seed germination particularly in the release of seed dormancy and embryogenesis, as well as in protection from pathogens.

Despite their importance in many aspects of plant physiology, information about the function of oxidative and, particularly, of nitrosative signalling in fruit biology is limited. Tanou

Roughly half of the species of bryophytes have separate sexes (dioecious) and half are hermaphroditic (monoecious). This variation has major consequences for the ecology and evolution

Cadmium (Cd) is a non-essential trace element that elicits oxidative stress. Plants respond to Cd toxicity via increasing their Cd-chelating and antioxidative capacities. They

Nascimento et al. expose plants to supplemental UV-B radiation and find that it causes the formation of brown areas on the leaves, which develop into a protective tissue on the adaxial side of the leaf, but only in directly exposed regions

Plants are sessile organisms that have the ability to integrate external cues into metabolic and developmental signals. The cues initiate specific signal cascades that can enhance
