DESCRIPTION OF THE OFFER
Phosphorus is one of the key macronutrients necessary for the growth of plants and of any living organism. plants preferentially absorb phosphorus in the form of phosphate (Pi), which is a quite immobile and insoluble ion in the soil. This has made Pi availability a major limiting factor in plant growth and productivity. To deal with growth under low Pi soils, plants have evolved an array of adaptive responses aiming to increase the efficiency in Pi acquisition and use. In or laboratory we have been working for the last 20 years in the genetic dissection of the signaling pathway of Pi starvation in plants, and have identified key signaling genes, particularly the PHR1 master transcription factor and the SPX sensor . At present, we are exploring natural variation of Pi starvation responses and are examining the conservation of the signaling pathway over evolutionary distant plant organisms (eg, vascular and non vascular plants). The student will contribute to the study of natural variation based on RNA-seq analysis and/or to the functional analysis of regulatory components in non vascular model plants
