Carbon dioxide concentrations in the atmosphere have gone up by a third since the mid 20th century. Parthenin concentrations in invasive Parthenium hysterophorus have gone up by a half.

Feeding (or not feeding) a fungus: plants may not be so good to their fungal partners after all
Interactions between plants and fungal symbionts are not always balanced affairs.

A long-lasting connection? Links between genome size and stomata size in plants
The variation in genome size between different plant species is enormous, with a variation of 2300-fold in flowering plants alone. Whilst variation in plant genome size is well recorded, it is debatable how much of this...
Night-time transpiration facilitates respiratory carbon dioxide release
Night-time transpiration accounts for a considerable amount of water loss in crop plants, yet its biological function, regulation and response to salt stress are poorly understood. Even et al. present data on barley...

Elevated carbon dioxide: Getting to the root of the problem
How will plants respond to rising carbon dioxide levels in the atmosphere? Botanists at BIFoR, the Birmingham Institute for Forest Research have gone underground to find some of the answers.

Grounds for climate change optimism?
When global warming and greenhouse gases are mentioned (and they are, seemingly endlessly, but does anybody listen? Does anybody do anything about it..?) [Ed. – Steady on, Mr C, the good people in Paris for COP 21 *...

Stomata and atmospheric CO2 in bryophytes
This study strengthens the hypothesis of incremental rather than early acquisition of stomatal regulatory processes through land plant evolution.

A unifying model for isoprene emission (Research in Context)
Morfopoulos et al. hypothesize that NADPH availability for isoprene biosynthesis depends on the balance of electron supply and Calvin cycle demand.
Cryptic contribution to N (and C) cycles
In this global-climate-change-obsessed world we frequently hear the term carbon sink, which is a ‘natural or artificial reservoir that accumulates and stores some carbon-containing chemical compound for an indefinite...
Calcium sensitivity and guard cells (Invited Review)
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...
