Transcription profiling of the effect of silicon on wheat plants infected or uninfected with powdery mildew

ABSTRACT: The supply of soluble silicon (Si) to plants has been associated with many benefits that remain poorly explained and often contested. In this work, the effect of Si was studied on wheat plants under both control and pathogen stress (Blumeria graminis f.sp. tritici (Bgt)) conditions by conducting an exhaustive transcriptomic analysis (55,000 genes) aimed at comparing the differential response of plants under four treatments. The response to the supply of Si on control (uninfected) plants was limited to 47 genes providing little evidence of regulation of a specific metabolic process. Plants reacted to inoculation with Bgt by an up-regulation of many genes linked to stress and metabolic processes and a down-regulation of genes linked to photosynthesis.
