MetabolomicsAccumulation of the coumarin scopolin under abiotic stress conditions is mediated by the Arabidopsis thaliana THO/TREX complex
Secondary metabolites are involved in the plant stress response. Among these are scopolin and its active form scopoletin, which are coumarin derivatives associated with reactive oxygen species scavenging and pathogen defence. Here we show that in Arabidopsis thaliana, scopolin accumulation can be in...

MetabolomicsExometabolomic profiling of bacterial strains cultivated using Arabidopsis root extract as the sole carbon source
The ability of microorganisms to use root-derived metabolites as growth substrates is a key trait for success in the rhizospheric niche. However, few studies describe which specific metabolites are consumed, or to what degree microbial strains differ in their substrate consumption patterns. Here we ...

TranscriptomicsTranscription profiling of Arabidopsis thaliana root parts in reaction to fungal (Laccaria bicolor) volatiles
Arabidopsis thaliana plants were grown from seeds in Petri dishes on MS medium. 4 days old plants were co-incubated with L. bicolor without physical contact. After 2 days of co-incubation, roots were either harvested whole or separated into the root tip (ca. 1/4 of the whole root) and the lateral ro...

TranscriptomicsTranscriptome Profiling of Roots and leaves Under High Osmotic Stress in Arabidopsis
The functions of miRNAs and their target mRNAs in Arabidopsis development have been widely documented, however, roles of stress responsive miRNAs and their targets are not as well understood. Using small RNA deep sequencing and ATH1 microarrays to profile mRNAs, we identified IAR3 (IAA-Ala Resistant...

TranscriptomicsTranscription profiling of Arabidopsis thaliana wild type Col-0) and Atpdr2 mutant roots.
To determine the pleiotropic effect of the ABC transporter gene (Atpdr2) mutation, we performed the microarray analyses on the root tissues of Arabidopsis thaliana wild type (Col-0) and Atpdr2 mutant.

GenomicsArabidopsis Root Methylation and Root Nucleosome Positioning
DNA methylation and nucleosome densities play a critical role in the regulation of gene expression. While much is known about the mechanisms of transcriptional control that are mediated by these, less is known about the degree to which they are tissue-specific. By comparing DNA methylation, nucleoso...

TranscriptomicsTranscription profiling of Arabidopsis leaves, roots and whole plants grown in high or low phosphate conditions for different lengths of time
The effects of phosphate starvation in Arabidopsis thaliana (L.) plants were compared in plants grown in liquid MS medium transferred in low or high Pi and in plants grown vertically in petri dishes during 10 days. In the transfer experiments, 2 treatments were analysed for evaluating the short-(3, ...

TranscriptomicsRecruitment of GSH into the nucleus during cell proliferation
The essential thiol antioxidant, glutathione (GSH) is recruited into the nucleus of mammalian cells early in cell proliferation, suggesting a key role of the nuclear thiol pool in cell cycle regulation. However, the functions of nuclear GSH (GSHn) and its integration with the cytoplasmic GSH (GSHc) ...

ProteomicsUnraveling epigenetic changes in A. thaliana calli: Impact of HDAC inhibitors
The aim was to characterize epigenetic changes in histone proteins during callus formation from roots and shoots of Arabidopsis thaliana seedlings using mass spectrometry-based approach. Increased level of histone H3.3 variant was found to be the most prominent feature of 20-day-old calli, associate...

TranscriptomicsThe response and recovery of Arabidopsis thaliana transcriptome to phosphate starvation [At35b_MR]
Background: Over application of phosphate fertilizers in modern agriculture contaminates waterways and disrupts natural ecosystems. Nevertheless, this is a common practice among farmers, especially in developing countries as abundant fertilizers are believed to boost crop yields. The study of plant ...
