Project description:Iron (Fe) deficiency is a yield-limiting factor for a variety of field crops across the world and generally results from the interaction of limited soil Fe bioavailability and susceptible genotype cultivation. Tomato, a Strategy I, model plant for Fe deficiency, is an important economical crop. Tomato responses in order to improve Fe uptake are based on acidification of rhizosphere, reduction of Fe3+ to Fe2+ and transport of Fe2+ into the cells.
Project description:Phosphate (P) fertilization impacts many rhizosphere processes, driving plant P use efficiency. However, less is known about the induced molecular and physiological root-rhizosphere traits in responses to polyphosphates (PolyP), particularly root transcriptome and belowground functional traits responsible for P acquisition. The present study aims to investigate physiological and transcriptomic belowground mechanisms explaining the enhanced durum wheat P acquisition under PolyP (PolyB and PolyC) supply. Root molecular traits were differentially expressed in response to PolyP, where PolyB induced upregulation of OGDH, MDH, and ENO, PAP21 and downregulation of PFK, and LDH genes. The modulation of gene expression can presumably explain the PolyP-induced changes in rhizosphere (root, rhizosphere soil, soil solution) acidification (pH decreased from 8 to 6.3) and acid phosphatase activities, which were concomitant with enhanced rhizosphere soil P availability and shoot Pi content (145% and 36% compared to OrthoP, respectively) along with changes in morphological and transcriptomic root (particularly, the upregulation of AUX1 and ABA transporter genes) traits. These findings provide novel insights that P acquisition from polyphosphates involves the coordinated regulation of genes governing root-rhizosphere processes and root development, ultimately enhancing wheat P acquisition.

Project description:Transcriptional profiling of M. avium subsp. paratuberculosis inside bovine monocyte-derived macrophages (MDMs; in vitro infection) during phagosome acidification at 30 min post-infection. M. avium subsp. paratuberculosis profiles from bafilomcyin A1 (acidification inhibitor) treated and untreated monocyte-derived macrophages were compared. Two-condition experiment; 3 control (bafilomcyin treated) and 3 test, independently conducted. 1 control, 1 test per microarray.
