Calorespirometry, oxygen isotope analysis and functional-marker-assisted selection ('CalOxy-FMAS') for genotype screening: A novel concept and tool kit for predicting stable plant growth performance and functional marker identification.

We propose a novel concept and tool kit for predictive phenotyping. The proposed technology measures respiration properties as functions of growth conditions to identify genotypes with higher plasticity via homeostasis and adaptive morphophysiology. Combining calorespirometry, oxygen isotope analysis and functional-marker-assisted selection ('CalOxy-FMAS') for genotype screening will enable predicting the genetic potential for stable plant growth performance. Application of this novel tool kit can help identify genotypes with controlled homeostasis in changing environments and optimized growth performance. Simultaneously, it will allow a better balance in breeding for high yields and quality characteristics. Applying 'CalOxy-FMAS' can efficiently narrow the pool of genotypes to be screened for final phenotyping in the field.
