Stomatal movements control CO 2 uptake for photosynthesis and water loss through transpiration, and therefore play a key role in plant productivity and water use efficiency. The predicted doubling of global water usage by 2030 mean that stomatal behaviour is central to current efforts to increase photosynthesis and crop yields, particularly under conditions of reduced water …

photosynthesis (Raven et al. 2005). Sunlight has also been found to open stomata and since transpiration, the evaporation of water from the stomata of a plant, increases as a plant’s stomata open, transpiration has been found to be a light dependent reaction as well (Von Caemmerer and Farquhar… Description: New Phytologist is a leading world journal, publishing original research papers on all aspects of the plant sciences. It publishes also a prestigious series of invited reviews, Tansley Reviews, named after Sir Arthur Tansley who founded the journal in 1902.In addition, submitted reviews are published as well as a Forum section containing short articles on current issues in the

Methylation of polysulfides [(NH4)2Sn)] by reaction with CF3SO3CH3 followed by separation of the produced dimethylpolysulfides by liquid chromatography and subsequent highly accurate stable isotope analysis by a continuous-flow isotope ratio mass spectrometer shows that polysulfide anions in an aqueous solution exchange isotopes with the other sulfur species in the system.

New Phytologist offers rapid publication of high quality, original research in plant science. Falling within four sections – Falling within four sections – Physiology & Development, Environment, Interaction and Evolution – articles cover topics that range from intracellular processes New Phytologist is an electronic (online-only) journal owned by the New Phytologist Trust, a not-for-profit organization dedicated to the promotion of plant science, facilitating projects from symposia to free access for our Tansley reviews.

In this issue of New Phytologist, Cramer et al. (pp. 000–000) have built on knowledge that transpiratory mass flow of water through soil is important in moving some nutrients to the root surface and present results consistent with the stimulation of nutrient supply to plant roots by mass flow through the soil as a component of the regulation The physiology of Salix - Volume 98 - J.
