CHD3 proteins are ATP-dependent chromatin remodelers that contribute to repression of developmentally regulated genes in both animal and plant systems. In animals, this repression has been linked to a multiple subunit complex, Mi-2/NuRD, whose constituents include a CHD3 protein, a histone deacetylase, and a methyl-CpG-binding domain protein. In Arabidopsis, PICKLE (PKL) codes for a CHD3 protein that acts during germination to repress expression of seed-associated genes. Repression of seed-assoc ...[more]

Impact of rhamnolipids (RLs), natural defense elicitors, on shoot and root proteomes of Brassica napus by a Tandem Mass tags (TMTs) labeling approach

Project description:The rapeseed crop (Brassica napus) is valued mainly for animal feed, food oil and biofuel production. This plant is particularly susceptible to many pathogens like parasitic plants, fungi or animals attacking aerial or root parts. Conventional plant protection products, used intensively in agriculture, have a negative impact on the environment (air and water quality, biodiversity, etc.) as well as on human health. There is therefore a growing demand for the development of new, more planet-friendly alternative protection methods such as biocontrol compounds. Natural rhamnolipids (RLs) can be used as elicitors of plant defense mechanisms. Indeed, these glycolipids, from bacteria secretome, are biodegradable, non-toxic and they are known for their stimulating and protective effects, in particular on rapeseed against filamentous fungi. Characterizing the organ responsiveness to defense stimulating compounds like RLs is missing. This analysis is crucial in the frame of optimizing the effectiveness of RLs against various diseases. A TMT labeling of the proteins extracted from the shoots and roots of B. napus has been performed and showed a differential pattern of protein abundance between them. These results have allowed identifying several protein families possibly involved in the differential responses observed in shoots and roots of rapeseed upon RLs treatment. In particular, quantitative proteomic analysis highlighted differential accumulation of parietal and cytoplasmic defense or stress proteins in response to treatments with RLs with a clear effect of the type of application (foliar spraying or root absorption). These results must be considered for further use of RLs to fight specific rapeseed pathogens.

Transcription profiling of a transgenic Arabidopsis seedling that expresses a constitutively active form of HsfA1d

Project description:HsfA1d is one of the three master regulators (HsfA1s; HsfA1a, b and d) in the heat stress response of Arabidopsis thaliana. The protein levels of these HsfA1s are steady before and after heat stress, suggesting the existence of post-translational regulation. Through analyses of a deletion series of the HsfA1d protein, we identified a regulatory domain in this protein. The deletion of this domain turned the HsfA1d protein into an active form, and its expression resulted in induction of heat stress-inducible genes at room temperature. This microarray experiment was conducted to identify genes that are regulated by the function of the newly identified regulatory domain of HsfA1d.

Transcription profiling of OsPIL1/DREB1A double-overexpressing Arabidopsis lines.

Project description:To improve both drought stress tolerance and growth of plants, we generated transgenic Arabidopsis plants that overexpress two transcription factors: DREB1A and OsPIL1. It was reported that DREB1A improves drought stress tolerance in various crops but causes dwarfism, and OsPIL1 enhances cell elongation through activation of cell wall synthesis in rice. We performed microarray experiments using a single overexpressor of OsPIL1 and the double overexpressor of DREB1A and OsPIL1 to study the potential interactions of the gene networks regulated by the two transcription factors in the double overexpressor.

Transcriptional profiling of Arabidopsis thaliana hsc70-1/2/3 triple mutant

Project description:HSC70 is the cytosolic isoform of plant HSP70. We have found that HSC70 family proteins bind to the heat shock transcription factor A1s (HsfA1s), which are the master regulators of the heat shock response in plants, and supress their activity. To investigate the role of HSC70s in the regulation of HsfA1s and heat shock responses, we evaluated the effect of triple knock out of HSC70s on the transcriptome under the normal growth condition.
