(Submitter supplied) Genome-wide transcriptional profiling of Arabidopsis thaliana to a combination of heatwave and drought under ambient and elevated CO2. Goal of this study was elucidate the transcriptional responses to a combination of heat wave and drought, and to see how these responses are modifed under future climate (high) CO2. Climate changes increasingly threaten plant growth and productivity. Such changes are complex and involve multiple environmental factors, including rising CO2 levels and climate extreme events. more...

(Submitter supplied) Plant respiration responses to elevated growth [CO2] are key uncertainties in predicting future crop and ecosystem function. In particular, the effects of elevated growth [CO2] on respiration over leaf development are poorly understood. This study tested the prediction that, due to greater whole-plant photoassimilate availability and growth, elevated [CO2] induces transcriptional reprogramming and a stimulation of nighttime respiration in leaf primordia, expanding leaves, and mature leaves of Arabidopsis thaliana. more...

(Submitter supplied) This study compared the photosynthetic performance and the global gene expression of the winter hardy wheat Triticum aestivum cv Norstar grown under non-acclimated (NA) or cold-acclimated (CA) condition at either ambient CO2 or elevated CO2 (EC). CA Norstar maintained comparable light saturated and CO2 saturated rates of photosynthesis but lower quantum requirements for photosystem II and non photochemical quenching relative to NA plants even at EC. more...

(Submitter supplied) Some aquaporins do not show a pronounced function as water diffusion facilitators but act as small molecule transport facilitators for substances such as urea, glycerol, boron or gases such as CO2 . Transcriptome analysis provided distinguishable, specific profiles for water stress or for conditions of increased or decreased CO2 concentrations We used Affymetrix microarray analysis to elucidate the function of the aquaporin AtPIP1;2 gene

(Submitter supplied) Considering global climate changes, incidences of combined drought and heat stress are likely to increase in the future and will considerably influence plant-pathogen interactions. Until now, little is known about plants exposed to simultaneously occurring abiotic and biotic stresses. To shed some light on molecular plant responses to multiple stress factors, a versatile multi-factorial test system, allowing simultaneous application of heat, drought and virus stress, was developed. more...

(Submitter supplied) We sequenced mRNA from leaves of Arabidopsis under the control (CK), warming (W) and heat (H) treatments using the Illumina HiSeq4000 platform to generate the transcriptome dynamics that may serve as a gene expression profile blueprint for different response patterns under prolonged warming versus rapid-onset heat stress in Arabidopsis.

(Submitter supplied) During low temperature exposure, temperate plant species increase their freezing tolerance in a process termed cold acclimation. During deacclimation in response to warm temperatures cold acclimated plants lose freezing tolerance and resume growth and development. While considerable effort has been directed toward understanding the molecular and metabolic basis of cold acclimation, much less information is available about the regulation of deacclimation. more...

(Submitter supplied) Introduction : By mid-century, global atmospheric carbon dioxide concentration ([CO2]) is predicted to reach 600 u­mol mol-1 with global temperatures rising by 2ºC. Rising [CO2] and temperature will alter the growth and productivity of major food and forage crops across the globe. Although the impact is expected to be greatest in tropical regions, the impact of climate-change has been poorly studied in those regions. more...

(Submitter supplied) Abstract: Drought is the primary cause of global agricultural losses and represents a major threat to worldwide food security. Currently, plant biotechnology stands out as the most promising strategy to increase crop growth in rain-fed conditions. The main mechanisms underlying drought resistance have been uncovered by studies of plant physiology and by engineering crops with drought-resistant genes. more...

(Submitter supplied) Our research describe the influence of aeration conditions in petri dishes for A. thaliana growth. We analyze the difference between plants grown in standard Petri dish (Non-aerated) and modified Petri dish that include aeration (Aerated). To characterize the differences between those conditions the gene expression analysis was performed. We also wanted to analyze the effect of using a micropore filter, so we designed another experiment with Aerated, Non-aerated and Micropore filter conditions.

(Submitter supplied) The photorespiratory pathway, short photorespiration, is an essential process in oxygenic photosynthetic organisms but also reduces the efficiency of photosynthetic carbon assimilation and is hence frequently considered as a wasteful process. By comparing the response of wild-type plants and mutants impaired in photorespiration to a shift in ambient CO2 concentrations, we demonstrate that photorespiration also plays a beneficial role during short-term acclimation to reduced CO2 availability. more...

(Submitter supplied) Carbon fixation plays a central role in determining cellular redox poise, increasingly understood to be a key parameter in cyanobacterial physiology. In the cyanobacterium Prochlorococcus--—the most abundant phototroph in the oligotrophic oceans--—the carbon-concentrating mechanism (CCM) is reduced to the bare essentials. Given the ability of Prochlorococcus populations to grow under a wide range of oxygen concentrations in the ocean, we wondered how carbon and oxygen physiology intersect in this minimal phototroph. more...
