(Submitter supplied) Iron (Fe) and phosphorus (P) are essential nutrients for plants growth. Despite their abundance in soils, they are barely available for plants. In order to overcome these nutritional stresses, plants have evolved strategies including physiological, biochemical and morphological adaptations. Biosynthesis and release of low molecular weight compounds from the roots play a crucial role in P and Fe mobilization. more...

(Submitter supplied) Iron deficiency is a yield-limiting factor and a worldwide problem for crop production in many agricultural regions, particularly in aerobic and calcareous soils. Graminaceous species, like maize, improve Fe acquisition through the release of phytosiderophores (PS) into the rhizosphere and the following uptake of Fe(III)-PS complexes through specific transporters. Transcriptional profile obtained by roots 12-d-old maize plants under Fe starvation for 1 week (Fe-deficient; 19-d-old plants) were compared with the transcriptional profile obtained by roots of 12-d-old maize plants grown in a nutrient solution containing 100 μM Fe-EDTA for 1 week (Fe-sufficient; 19-d-old plants).

(Submitter supplied) Purpose: The aim of this study was to identify the specific transcriptomic changes in apple root tissue in response to infection by F. Proliferatum.The characterized transcriptome changes during apple root defense responses to F. Proliferatum inoculation should facilitate the identification of the key molecular components, which may differentiate the resistance and susceptibility among apple rootstock germplasm.

(Submitter supplied) Essential metals such as iron are required for healthy plant growth. Fe is an important cofactor and catalytic element in many biological processes. Fe and other metals can also be toxic when present in excess. Therefore plants have mechanisms of metal homeostasis which involve coordination of metal ion transporters for uptake, translocation and compartmentalisation. The NAS genes are supposed to play an important role in Fe homeostasis. more...

(Submitter supplied) Phosphorus (P) and iron (Fe) deficiency are major limiting factors for plant productivity worldwide. White lupin (Lupinus albus L.) has become a model plant for understanding plant adaptations to P and Fe deficiency, because of its ability to form cluster roots, bottle-brush-like root structures that play an important role in the uptake of P and Fe from soil. However, little is known about the signaling pathways involved in sensing and responding to P and Fe deficiency. more...

(Submitter supplied) In the early stages (30 days) of phosphorus deficiency stress, Epimedium pubescens leaves cope with short-term phosphorus deficiency by increasing the expression of related genes such as carbon metabolism, flavonoid synthesis and hormone signal transduction pathways, producing sufficient energy, scavenging ROS, and adjusting plant morphology. However, with the extension of stress duration to 90 days, the expression of genes related to phosphorus cycling and phosphorus recovery (PHT1-4, PHO1 homolog3, PAP) was upregulated, and transcriptional changes and post-transcriptional regulation (miRNA regulation and protein modification) were enhanced to resist long-term phosphorus deficiency stress. more...

(Submitter supplied) Tomato, a Strategy I model plant for Fe deficiency, is an important economical crop. The transcriptional responses induced by Fe deficiency in tomato roots were previously described (Zamboni et al., 2012). The changes in trascriptome caused by the supply of Fe to plants starved fro 1 week were described in relation to the different nature of chelating agents (Fe-WEHS, Fe-CITRATE and Fe-PS).

(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) 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) Root and leave samples of 4 different apple genotypes were investigated in order to analyse the gene expression after infection with Apple Replant Disease (ARD). All genotypes were cultivated in ARD-infected soil and gamma-irradiated (disinfected) soil in the greenhouse for 7 days. The ARD soil originated from two different orchards representing two different soil compositions. After 7 days root tissue was collected from each plant and used for the subsequent gene expression analysis. more...
