Project description:Small RNA sequences from Arabidopsis thaliana Col-0 inflorescence tissues of three biological replicates. The data were analyzed to identify non-templated nucleotides in Arabidopsis small RNAs.
Project description:Plants often face combinatorial stresses in their natural environment. Here arsenic (As) toxicity was combined with hypoxia (Hpx) in the roots of Arabidopsis thaliana as it often occurs in nature. The present work aimed to explore the effects of single and combined hypoxia and As stress applied at realistic stress levels to hydroponically grown A. thaliana. Arsenic as well as hypoxic growth conditions generate a characteristic signaling pattern, a significant part of which is mediated by ROS. The current study utilized the microarray to determine the overlapping signalling pattern and changes in gene expression for the defined stress combinaton compared to individual stresses.
Project description:Investigation of whole genome gene expression level changes in several Arabidopsis thaliana mutants (nrpd1, nrpe1, ros1 dml2 dml3) compared to wild-type Col-0. The mutants analyzed in this study are further described in Le et al. 'DNA demethylases target promoter transposable elements to positively regulate stress responsive genes in Arabidopsis' .
