(Submitter supplied) Background: The unprecedented rise in atmospheric CO2 concentration and injudicious fertilization or heterogeneous distribution of Mg in the soil warrant further research to understand the synergistic and holistic mechanisms involved in the plant growth regulation. The objective of this work is to understand responses in plants along with interactive effect of elevated CO2 and Mg levels by comparing data on single stress with that of combined stresses. 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) gnp06-01_agriarray - multiplexage : dual-target hybridization microarray experiment - Several factors affect today a more extended use of microarrays for research and as a diagnosis tool. These factors are the experimental cost, the reproducibility of the measurements and the format of the analyses. This project aims at bringing solutions in these three domains by optimizing multiplexed analyses in order to reduce cost and enhance the number of samples treated simultaneously; by proposing new couples flurophores / slide surface in order to increase the signal precision and by developing new applications such as Comparative Genomic Hybridization (GGH) or Promoter Arrays to bring the plant microarray beyond transcriptome analyses. more...

(Submitter supplied) Nitrogen availability in the soil is a major determinant of crop yield. While the application of fertilizer can substantially increase the yield on poor soils, it also causes nitrate pollution of water resources and high costs for farmers. Increasing the nitrogen use efficiency in crop plants is a necessary step to implement low input agricultural systems. We exploited the genetic diversity present in the world-wide Arabidopsis thaliana population to study adaptive growth patterns and changes in gene expression associated with chronic low nitrate stress, with the aim to identify biomarkers associated with good plant performance under low nitrate availability. more...

(Submitter supplied) Illumina HiSeq technology was used to generate mRNA profiles from in vitro Eucalyptus grandis roots interacting with two different Pisolithus microcarpus strains (SI-9 and SI-12) and under two different CO2 concentrations (400 and 650 ppm) . Control roots or ectomycorrhizal root tips were harvested after 1 month and used for RNA extraction. Paired-end (2X150bp) reads were generated and aligned to Eucalyptus grandis transcripts (http://www.phytozome.net/; primarytranscripts only) using CLC Genomics Workbench 6.

The role of BTS in root tissues has been well established. However, its role in shoot tissues has been scarcely studied. Comparative transcriptome analysis with shoot and root tissues revealed that BTS is involved in regulating energy metabolism by modulating expression of mitochondrial and chloroplast genes in shoot tissues. more...

(Submitter supplied) Plant growth response to elevated levels of CO2 in the environment needs to be deeply investigated to understand the impact of rising global carbon dioxide levels. While the response of plants directly exposed to elevated CO2 is relatively well-studied, the trans-generational impact of elevated CO2 exposure in plants returned to ambient conditions is unexplored. In this study, we show that plants develop a trans-generational memory of elevated CO2 exposure in the next generation even after returning the plants to ambient CO2 levels. more...
