Project description:Iodine treatments specifically regulated the expression of several genes in shoot and root tissues, mostly involved in the plant defence response, suggesting the protective role of iodine against both biotic and abiotic stresses.
Project description:Biotic and abiotic stresses limit agricultural yields, and plants are often simultaneously exposed to multiple stresses. Combinations of stresses such as heat and drought or cold and high light intensity, have profound effects on crop performance and yeilds To analyze such responses, we initially compared transcriptome changes in ten Arabidopsis thaliana ecotypes using cold, heat, high light, salt and flagellin treatments as single stress factors or their double combinations.
Project description:We intend to provide a high resolution compendium of changes in gene expression of Arabidopsis root upon exposure to Fe starvation, an important abiotic stress.

Arabidopsis thaliana plants of ecotypes (Col, Ler, C24, Cvi, Kas1, An1, Sha, Kyo2, Eri and Kond) were subjected to the following stress treatments: Salt, Cold, Heat, High Light (HL), Salt+Heat, Salt+HL, Cold+HL, Heat+HL, as well as FLG (Flagellin, flg22 peptide), Cold+FLG, Heat+FLG
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:Genetically engineering Arabidopsis thaliana to express Isoprene Synthase (ISPS) leads to changes in expression of genes assoiated with many growth regulator signaling pathways and signaling networks involved in abiotic and biotic stress responses.
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.
