Metabolic Markers and Metabolite Quantitative Trait Loci (mQTLs) for the Breeding of Crop Quality and Resistance Book in Scopus uri icon

abstract

  • Metabolites are crucial for plant resistance against abiotic and biotic stresses, such as heat, drought, pathogens, and herbivore attacks. At the same time, the chemical composition of plants defines their quality as food or industrial raw material. Therefore, plant phytochemical phenotypes are highly informative for target-directed breeding. Data mining strategies permit the development of predictive models and the identification of plant breeding markers. Metabolite quantitative trait loci (mQTLs) provide a means to elucidate the genetic control of metabolic pathways and therefore help to identify genetic regions associated with plant stress resistance. Integrating mQTL analyses, advanced omics technologies, and high-throughput phenotyping support a comprehensive understanding of plant stress resistance mechanisms and the development of targeted-breeding strategies. Such a multi-dimensional approach holds great promise for accelerating the development of resilient crop varieties that can withstand diverse challenges, ensuring sustainable agriculture and global food security in an ever-changing environment. © 2025 Taylor & Francis Group, LLC.
