Although open stomata are necessary for plants to take up CO2 for photosynthesis, this also permits loss of precious water – by transpiration, the so-called necessary evil of photosynthesis. But, surely, nothing worse...
The long-held notion that the sporophyte shoot is homologous with the seta of mosses has been questioned, but no alternative evolutionary model has hitherto been proposed. Ligrone et al. explore the origin of the...
Land plants arose from a common ancestor at least 470 million years ago and presently encompass four major lineages: liverworts, mosses, hornworts and tracheophytes. By integrating paleontological, morphological...
Stomatal aperture is regulated by the stress-induced phyto-hormone abscisic acid (ABA), and by CO2 and Ca2+ concentrations. Hubbard et al. review the topic and propose models to explain the specificity of signalling for...
