Currently, modeling studies tend to significantly underestimate observed space-based glyoxal （CHOCHO） vertical column densities （VCDs）, implying the existence of missing sources of giyoxal. Several recent studies suggest that the emissions of aromatic compounds and molar yields of glyoxal in the chemical mechanisms may both be underestimated, which can affect the simulated glyoxal concentrations. In this study, the influences of these two factors on glyoxal amounts over China were investigated using the RAMS-CMAQ modeling system for January and July 2014. Four sensitivity simulations were performed, and the results were compared to satellite observations. These results demonstrated significant impacts on glyoxal concentrations from these two factors. In case 1, where the emissions of aromatic compounds were increased three-fold, improvements to glyoxal VCDs were seen in high anthropogenic emissions regions. In case 2, where molar yields of glyoxal from isoprene were increased five-fold, the resulted concentrations in July were B-B-fold higher, achieving closer agreement between the modeled and measured glyoxal VCDs. The combined changes from both cases 1 and 2 were applied in case B, and the model succeeded in further reducing the underestimations of glyoxal VCDs. However, the results over most of the regions with pronounced anthropogenic emissions were still underestimated. So the molar yields of giyoxal from anthropogenic precursors were considered in case 4. With these additional mole yield changes （a two-fold increase）, the improved concentrations agreed better with the measurements in regions of the lower reaches of the Yangtze River and Yellow River in January but not in July.

Dear Editor, Plant cell suspension cultures have been used as model systems to circumvent the problems associated with the analyses of a multi-factorial plant that is composed of multiple tissue and cell types exposed to diverse signals. A number of plant suspension cultures have proven to be valuable to study various topics including defense response, secondary metabolite formation, ion transport, gene regulation, and signal duction （Roitsch and Sinha, 2002 and references therein）. However, most cultures reported to date, including the cultures from model species such as Arabidopsis （Christie and Jenkins,

Plastids communicate their developmental and physiological status to the nucleus via retrograde signaling,allowing nuclear gene expression to be adjusted appropriately.Signaling during plastid biogenesis and responses of mature chloroplasts to environmental changes are designated“biogenic”and“operational”controls,respectively.A prominent example of the investigation of biogenic signaling is the screen for gun(genomes uncoupled)mutants.Although the first five gun mutants were identified 30 years ago,the functions of GUN proteins in retrograde signaling remain controversial,and that of GUN1 is hotly disputed.Here,we provide background information and critically discuss recently proposed concepts that address GUN-related signaling and some novel gun mutants.Moreover,considering heme as a candidate in retrograde signaling,we revisit the spatial organization of heme biosynthesis and export from plastids.Although this review focuses on GUN pathways,we also highlight recent progress in the identification and elucidation of chloroplast-derived signals that regulate the acclimation response in green algae and plants.Here,stress-induced accumulation of unfolded/misassembled chloroplast proteins evokes a chloroplast-specific unfolded protein response,which leads to changes in the expression levels of nucleus-encoded chaperones and proteases to restore plastid protein homeostasis.We also address the importance of chloroplast-derived signals for activation of flavonoid biosynthesis leading to production of anthocyanins during stress acclimation through sucrose non-fermenting 1-related protein kinase 1.Finally,a framework for identification and quantification of intercompartmental signaling cascades at the proteomic and metabolomic levels is provided,and we discuss future directions of dissection of organelle-nucleus communication.

Satellite derived NO2 column data have been used to study Chinese national fossil fuel consumption and pollutant emissions.Based on NO 2 retrievals from two satellites (GOME and SCIAMACHY) for 1996-2010,we analyzed the characteristics and evolution of regional pollution related to NO x emissions in China.Satellite observations indicated that the highly polluted regions were expanding.Anthropogenic emission dominated areas have expanded from the east to central and western China,and new highly polluted regions have formed throughout the nation.Bottom-up emission estimates suggested a 133% increase in anthropogenic NOx emissions in East Central China during 1996 to 2010,which was lower than the 184% increase of the NO2 columns measured by the satellites.We found that growth rates of NOx emissions have slowed in Chinese megacities over recent years,in contrast to which,the NOx emissions were soaring in medium-sized cities,indicating that strict controls of NOx emissions from coal-fired facilities are required in China.

In photosynthetic organisms, tetrapyrrole-mediated retrograde signals are proposed to contribute to a bal- anced nuclear gene expression （NGE） in response to metabolic activity in chloroplasts. We followed an experimental short- term approach that allowed the assessment of modified NGE during the first hours of specifically modified enzymatic steps of the Mg branch of tetrapyrrole biosynthesis, when pleiotropic effects of other signals can be avoided. In response to 24-h-induced silencing of CHLH, CHLM, and CHL27 encoding the CHLH subunit of Mg chelatase, the Mg protoporphyrin methyltransferase and Mg protoporphyrin monomethylester cyclase, respectively, deactivated gene expression rapidly led to reduced activity of the corresponding enzymes and altered Mg porphyrin levels. But NGE was not substantially altered. When these three genes were continuously inactivated for up to 4 d, changes of transcript levels of nuclear genes were determined. CHL27 silencing for more than 24h results in necrotic leaf lesions and modulated transcript levels of oxidative stress-responsive and photosynthesis-associated nuclear genes （PhANGs）. The prolonged deactivation of CHLH and CHLM results in slightly elevated transcript levels of PhANGs and tetrapyrrole-associated genes. These time-resolved studies indicate a complex scenario for the contribution of tetrapyrrole biosynthesis on NGE mediated by IO2-induced signaling and feedback-regulated ALA synthesis.

Plants have evolvedmultiple strategies to cope with rapid changes in the environment.During high light(HL)acclimation,the biosynthesis of photoprotective flavonoids,such as anthocyanins,is induced.However,the exact nature of the signal and downstreamfactors forHL induction of flavonoid biosynthesis(FB)is still under debate.Here,we show that carbon fixation in chloroplasts,subsequent export of photosynthates by triose phosphate/phosphate translocator(TPT),and rapid increase in cellular sugar content permit the transcriptional and metabolic activation of anthocyanin biosynthesis during HL acclimation.In combination with genetic and physiological analysis,targeted and whole-transcriptome gene expression studies suggest that reactive oxygen species and phytohormones play only a minor role in rapid HL induction of the anthocyanin branch of FB.In addition to transcripts of FB,sugar-responsive genes showed delayed repression or induction in tpt-2 during HL treatment,and a significant overlapwith transcripts regulated by SNF1-related protein kinase 1(SnRK1)was observed,including a central transcription factor of FB.Analysis of mutants with increased and repressed SnRK1 activity suggests that sugar-induced inactivation of SnRK1 is required for HL-mediated activation of anthocyanin biosynthesis.Our study emphasizes the central role of chloroplasts as sensors for environmental changes as well as the vital function of sugar signaling in plant acclimation.
