Project description:bra-inra09-01_bioen - cordycepin - Diversification of the Molecular Mechanisms Involved in the Control of the Energetic Balance in Angiosperms - To evaluate the importance of mRNA stability control in glucose signaling, genome wide RNA transcript levels changes will be evaluated in response to short term treatments with glucose or glucose plus abscisic acid (ABA) under conditions of transcriptional inhibition in Arabidopsis. The underlying mechanisms will be investigated for a selected number of co-regulated genes (transcription factors, kinases). 12 dye-swap - treatment variations

Project description:bra-inra09-01_bioen - bzip9 - Diversification of the Molecular Mechanisms Involved in the Control of the Energetic Balance in Angiosperms - To elucidate the role of selected bZIP transcription factors (AtbZIP3, AtbZIP9, AtbZIP63; the expression of these genes is repressed by glucose and are poorly characterized) involved in glucose-triggered transcriptional cascade, the target genes of these bZIP TF will be identified. The glucose-mediated regulations of these bZIP genes will be investigated by identifying the cis-regulatory sequences and the upstream regulatory factors. The functional conservation of the corresponding bZIP orthologues in sugar cane and rice will be evaluated. 12 dye-swap - genotype comparison

Project description:The role of abscisic acid (ABA) signalling in the ascorbic acid (AA)-dependent control of plant growth and defence was determined using the vtc1 and vtc2 mutants, which have impaired ascorbic acid synthesis, and in the abi4 mutant that is impaired in ABA-signalling. ABA levels were increase in the mutants relative to the wild type (Col0). Like vtc1 the vtc2 mutants have a slow growth relative to Col0. However, the wild type phenotype is restored in the abi4vtc2 double mutant. Similarly, the sugar sensing phenotype of in the abi4 is reversed in the abi4vtc2 double mutant. The vtc1 and vtc2 leaf transcriptomes show up to 70 % homology with abi4. Of the transcripts that are altered in the mutants a relative to Col0, only a small number are reversed in the abi4vtc2 double mutants relative to either abi4 or vtc2. We conclude that AA controls growth via an ABA and abi4-dependent signalling pathway. The vtc and abi4 mutants have enhanced glutathione levels and common redox signalling pathways leading to similar gene expression patterns.
