(Submitter supplied) Purpose: plants exposed to multiple simultaneous adverse growth conditions trigger molecular responses that differ from the sum of those to individual stressors. Copper and iron are fundamental elements required for proper photosynthesis, energy production, DNA metabolism and hormone sensing, among all. Therefore, copper and iron deprivation limits plant yield. In natural environments, simultaneous deficiency to copper and iron can occur. more...

(Submitter supplied) Iron (Fe) is an essential plant micronutrient, and its deficiency limits plant growth and development on alkaline soils. Under Fe deficiency, plant responses include upregulation of genes involved in Fe uptake from the soil. However, little is known about shoot responses to Fe deficiency. Using microarrays to probe gene expression in Kas-1 and Tsu-1 ecotypes of Arabidopsis thaliana revealed conserved rosette gene expression responses to Fe deficiency. more...

(Submitter supplied) Iron and copper are important environmental nutrients for plant growth. However, the molecular mechanisms of both iron and copper signaling that integrate the two pathways remain poorly understood. The Arabidopsis thaliana high affinity copper transporter COPT5, is a tonoplast localized permease involved in copper remobilization. Here, a global expression microarray analysis of the copt5 mutant points out the induction of iron deficiency responses, including NATURAL RESISTANCE-ASSOCIATED MACROPHAGE PROTEIN 4 (NRAMP4), a tonoplast-localized iron transporter. more...

(Submitter supplied) Deprivation of mineral nutrients causes significant retardation of plant growth. This slow growth is assumed to be associated with both nutrient specific transcriptional responses and additionally with common transcription patterns. In this study we adjusted the external supply of iron, potassium and sulfur to cause a similar retardation of growth. Global transcriptome analyses were performed to investigate whether the growth limitation by the different nutrient deficiencies triggered specific or similar transcriptional responses. more...

(Submitter supplied) Illumina 100bp single end sequencing was used to profile the transcriptomes of wild type (Columbia) and opt3-2 mutant Arabdiopsis leaves and roots under hydroponic conditions ( 4 weeks old, bolting stage). Sequencing resulted in 381 million uniquely mapping reads accross 36 libraries. Each sample was barcoded and divided into three sequencing lanes, while each genotype/tissue combination is represented by 3 biological replicates consisting of 3-4 individual plants (2 genotypes x 2 tissues x 3 biological replicates x 3 technical replicates = 36 libraries). more...

(Submitter supplied) Plants acclimate to environmental fluctuations by transitory reconfigurations the homeostatic network. Primary studies suggested that transcriptome responses to deal with fluctuations in light intensity and temperature tend to reversibility after stress removal in the model plant Arabidopsis thaliana. To gain more insight into this pattern in the context of acclimation, RNA-Seq analysis were conducted in Arabidopsis thaliana after different abiotic stress treatments consisting in high light (HL), high humidity, drought, heat, cold and combinations among factors or after recovery periods. more...

(Submitter supplied) Magnesium (Mg) is essential for many biological processes in plant cells and its deficiency causes yield reduction in crop systems. Low Mg status reportedly impacts on photosynthesis, sucrose partitioning and biomass allocation. However, earlier responses to Mg deficiency are scarcely described. Generally, symptoms of nutrient deficiency appear in specific ages of leaves. Therefore, we hypothesised that transcriptional responses to Mg deficiency are different depending on the ages of leaves, and performed a global transcriptomic analysis in two types of leaves; source and sink leaves of the model plant species Arabidopsis thaliana to reveal the earlier responses to Mg deficiency. more...
