(Submitter supplied) Arabidopsis wild-type plants (Col-0 accession) were grown on control (+Fe+P) for 7 days on 0.1X MS then transferred to three different medium: control (+Fe+P), iron deficiency (-Fe+P), and iron and phosphate deficiency conditions (-Fe-P). Shoots were collected 39 h, 52 h and 76 h after the transfer. For RNA-seq experiments, three biological replicates were used for each time point (39h, 52h and 76h) and each condition (+Fe+P, -Fe+P and -Fe-P) for a total of 27 samples.

(Submitter supplied) Iron (Fe) is an essential micronutrient for the survival and proliferation of plants. Plants have evolved complex mechanisms to maintain Fe homeostasis in response of Fe deficiency conditions. To explore the mechanisms of Populus tomentosa response to Fe deficiency, we evaluated the physiological, biochemical and transcriptome differences of P. tomentosa between Fe-sufficient and Fe-deficient conditions. more...

(Submitter supplied) Reduced glutathione (GSH) is required for cell cycle initiation and auxin-regulated root meristem development. Transcriptome profiling of the roots and shoots of the root meristemless 1 (rml1) mutant, which has about 3% of the wild type GSH, revealed a divergent auxin and strigolactone response linked to the arrest of the cell cycle.

(Submitter supplied) Iron–sulfur (Fe–S) clusters play an essential role in plants as protein cofactors mediating diverse electron transfer reactions. Because they can react with oxygen to form reactive oxygen species (ROS) and inflict cellular damage, the biogenesis of Fe–S clusters is highly regulated. A recently discovered group of 2Fe–2S proteins, termed NEET proteins, was proposed to coordinate Fe–S, Fe and ROS homeostasis in mammalian cells. more...

(Submitter supplied) Copper and iron are essential micronutrients for most living organisms because they participate as cofactors in biological processes including respiration, photosynthesis and oxidative stress protection. In many eukaryotic organisms, including yeast and mammals, copper and iron homeostases are highly interconnected; however such interdependence is not well established in higher plants. Here we propose that COPT2, a high-affinity copper transport protein, functions under copper and iron deficiencies in Arabidopsis thaliana. more...

(Submitter supplied) • Selected soil-borne rhizobacteria can trigger an induced systemic resistance (ISR) that is effective against a broad spectrum of pathogens. In Arabidopsis thaliana, the root-specific transcription factor MYB72 is required for the onset of ISR, but is also associated with plant survival under conditions of iron deficiency. Here we investigated the role of MYB72 in both processes. • To identify MYB72 target genes, we analyzed the root transcriptomes of wild-type Col-0, mutant myb72, and complemented 35S:FLAG-MYB72/myb72 plants in response to ISR-inducing Pseudomonas fluorescens WCS417. more...

(Submitter supplied) Citrus species are among the most important fruit crops. However, gene regulation and signaling pathways related to etiolation in this crop remain unknown. Using Illumina sequencing technology, modification of global gene expression in two hybrid citrus cultivars—Huangguogan and Shiranuhi, respectively—were investigated. More than 834.16 million clean reads and 125.12 Gb of RNA-seq data were obtained, more than 91.37% reads had a quality score of Q30 (sequencing error rate, 0.1%). more...

(Submitter supplied) Iron-deficiency repsonses in Arabidopsis are controlled by several bHLH transcription factors. FIT, for example has been shown to direct iron-uptake responses. However, the role of shoot and root expressed genes bHLH100 and bHLH101 has not be clarified. We used microarray to study what genes might be miss-regulated in the double mutant bhlh100/bhlh101 background

(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) Higher plants have developed sophisticated mechanisms to efficiently acquire and use micronutrients such as copper and iron. In the present work, we studied effects produced by the presence of a wide copper range in growth media and altered copper transport on iron homeostasis in Oryza sativa plants. The global analysis of gene expression in the rice seedlings grown under copper deficiency versus excess in the medium showed an increased expression of the genes involved in iron homeostasis. more...
