TL;DR: Widespread changes in the expression of genes encoding receptor kinases, transcription factors, components of signalling pathways, proteins involved in post-translational modification and turnover, and proteins involved with the synthesis and sensing of cytokinins, abscisic acid and ethylene revealing large-scale rewiring of the regulatory network is an early response to sugar depletion are revealed.

TL;DR: Hundreds of Arabidopsis genes were found that outperform traditional reference genes in terms of expression stability throughout development and under a range of environmental conditions, and the developed PCR primers or hybridization probes for the novel reference genes will enable better normalization and quantification of transcript levels inArabidopsis in the future.

TL;DR: GD, The Golm Metabolome Database is presented, an open access metabolome database, which provides public access to custom mass spectral libraries, metabolite profiling experiments as well as additional information and tools, e.g. with regard to methods, spectral information or compounds.

TL;DR: It is concluded that control is usually shared between Rubisco (which responds sensitively to CO2) and other components (which respond less sensitively), and that photosynthesis will be stimulated by 25–75% when the CO2 concentration is doubled from 35 to 70 Pa.

TL;DR: It is shown here that miR399 primary transcripts are also strongly induced by low Pi and rapidly repressed after addition of Pi, which placesmiR399 and PHO2 in a branch of the Pi-signaling network downstream of PHR1.
