Priming for enhanced defense as a strategy to optimize crop resistance and as a possible breeding target - PrimedPlant2 (PrimedPlant2)
Project
Project code: JKI-RS-08-3421
Contract period: 01.02.2020
- 28.01.2023
Purpose of research: Experimental development
The combination of priming-responsive genomes with resistance- or priming-inducing strains, consortia or soil microbiome has great potential. It is the key innovation of our approach, and we are confident that it will lead to novel approaches. In the second phase (PrimedPlant2), we intent to implement the finding from the first phase and transfer them into field conditions. The aim is to prove their applicability for growers on the one hand (direct use of the biologicals) and for the breeding companies, on the other (identified markers and QTLs along with the barley lines). Our principal effort will be a field experiment conducted on two different sites in Germany, in which the chosen set of seven barley accession (7’set) will be tested for their priming effects. This experimental setup requires the expertise of all consortium members: breeding, microbiology, plant physiology, genetics and phytopathology. The information on QTLs identified upon priming for enhanced resistance against P. hordei will be compared to QTL associated with priming for P. teres-resistance, i.e. to assess the information whether the respective QTLs are pathogen specific or universally involved in the priming phenomenon. This information will be extended with transcriptome and metabolome analyzes. An additional effect of the identified microbiota on root growth may have positive effects on the nutrient uptake, also under unfavorable conditions, such as drought stress.
